- The Spread of Sin
control, it remains an intruder—something He permits, governs, and will one day remove forever.
This is our hope: the God who allowed sin for a time will also defeat it forever. In Christ, the curse is being reversed. And in the new heavens and new earth, there will be no more sin—only righteousness, joy, and the glory of God.
The Spread of Sin Sin Is a Universal Reality When Adam and Eve first sinned, the consequences were devastating
—not only for themselves but for the entire human race. From that moment, all their descendants have shared in guilt, corruption, and the sentence of death. Every person is affected. This truth is not just found in the Bible but is also recognized—even if imperfectly—by people across cultures and religions. Wherever people are serious about morality, they feel the weight of sin. Sacrifices, prayers, philosophies, and religious rituals all reveal a common human awareness: something is wrong with us.
Ancient writers said things like:
"To sin is common to all people."
"No one is born without defects."
"There will be faults as long as there are humans."
But the Bible speaks more clearly and deeply about the matter. After the fall in Genesis 3, Scripture traces the spread of sin throughout the world. Before the flood, God saw that every thought of the human heart was only evil all the time (Genesis 6:5). Even after the flood,
God declared that the human heart remains evil from youth (Genesis 8:21).
God's people have always confessed this. Job asks, "Who can bring a clean thing out of an unclean?" (Job 14:4). Solomon says that no one lives without sin (1 Kings 8:46). The Psalms declare that no one does good—not even one (Psalm 14; 53). The heart is deceitful (Jeremiah
17:9), and no one can stand righteous before God (Psalm 143:2).
The New Testament Confirms This The gospel assumes that all are sinners. When John the Baptist came, he called Israel to repent—not just pagans, but God's covenant people—because their outward obedience could not produce true righteousness. Jesus taught the same. No one enters the kingdom of God without new birth, repentance, and faith (John 3:3, 5). Even when Jesus refers to the "healthy" or the "righteous," it's only in the sense that some think they are well—he shows in other places that all need saving grace.
The apostles preach the same message. Peter and Paul both declare that everyone—Jew and Gentile alike—needs forgiveness and renewal by the Holy Spirit (Acts 2:38; 10:43). Paul's letter to the Romans lays out in detail that the whole world is guilty before God.
No one will be declared righteous by works of the law (Romans 3:19– 20). "All have sinned" (Romans 3:23), and "the whole world lies under the power of the evil one" (1 John 5:19).
Because of this, the word "world" in Scripture often takes on a negative meaning. Although created by God, the world is now opposed to Him (John 1:10; 14:30). It is under the rule of Satan and filled with sinful desires (1 John 2:16–17).
Sin Starts at the Beginning of Life Sin doesn't begin with bad choices in adulthood. Scripture teaches that we are sinful from the very beginning—from conception and birth (Psalm 51:5; Job 14:4; Ephesians 2:3). Jesus said that what is born of the flesh is flesh (John 3:6), meaning that human nature, in its fallen state, cannot produce anything pleasing to God without spiritual rebirth. Paul says that by nature, we are "children of wrath"
(Ephesians 2:3), born into a condition of sin.
Sin is not something outside of us—it's within us. It affects every part of who we are: heart, mind, soul, spirit, conscience, desires, will, and even the body. Our minds are darkened, our hearts are corrupt, and our wills are enslaved. We need cleansing, rebirth, and grace at every level.
Even the godliest people in Scripture—Moses, Job, David, and Paul— confess their sin. Their lives show us that the closer we come to God, the more we recognize our need for mercy. They cried out in prayer and song for forgiveness and renewal.
What About Romans 7?
Some claim that Romans 7 shows that sin only affects the body, not the mind or spirit—that a person can be morally good deep down.
But the church has long understood that in this passage Paul is
describing the experience of a believer. Even after being born again, Christians still battle against sin. The regenerate person delights in God's law but feels torn because of the sinful nature still within.
Paul says he does the very things he hates, not because he approves of sin, but because sin still dwells in his flesh. He calls himself
"wretched," not because he is unregenerate, but because he longs to be free from the war within. He rejoices in God through Jesus Christ and serves the law of God with his mind, even while struggling in the flesh.
This shows just how deep sin runs. If the regenerate person still groans under the burden of sin, how much more the unregenerate?
Apart from grace, we are completely bound to sin—our hearts are at war with God, and we cannot please Him.
In Adam's Fall Although Genesis 3 doesn't explicitly explain the universality of sin, it shows the consequences of Adam's disobedience. After Adam and Eve sinned, they experienced shame, fear, and guilt. They hid from God's presence, and their punishment extended beyond themselves to their descendants. The human story, from that point on, becomes one of sin, sorrow, and death. Later Scripture confirms that humans are born with hearts inclined to evil (Gen. 6:5; 8:21).
But it is the apostle Paul who makes this connection between Adam's sin and the sinfulness of all people fully clear. In 1 Corinthians
15:21–22, he writes that just as death came through one man (Adam), so life comes through one man (Christ). In Romans 5:12–
21, Paul explains that through Adam's sin, both sin and death entered the world and spread to all people—because all sinned.
Here, Paul does not say that each person dies because of their own sin alone. Rather, death reigns even over those who have not sinned like Adam, including infants. Adam's sin introduced sin as a reigning power in the world, and all people come under its rule. This makes
Adam a pattern—a type—of Christ. Just as Adam's act brought condemnation and death to many, so Christ's obedience brings justification and life to many.
Paul's teaching is this:
1. Adam sinned.
2. God pronounced judgment—guilt and death—not just on Adam, but on all humanity.
3. As a result, all people were made sinners and die individually.
Just as believers are united to Christ and receive His righteousness and life, so all humans are united to Adam and inherit his guilt and death. We are condemned in Adam, just as we are justified in Christ.
The Pelagian Objection to Original Sin Some, like Pelagius in the early church, rejected this idea of original sin. He believed that Adam's sin harmed only himself and that people today are born just like Adam before the fall—pure and morally neutral. According to Pelagius, humans sin only by imitation, not by nature. Each person is responsible only for their own choices, and everyone is fully able to live a sinless life by free will alone. Grace, in his view, is helpful but not necessary.
This view has roots not only in Pelagius's teaching but in much ancient philosophy, which often praised human nature as basically
good. Many believed that virtue is already planted in the heart, and evil is something learned from others or chosen later in life.
Even after Pelagianism was officially condemned, versions of it reappeared. The Roman Catholic Church, for example, taught that though Adam lost certain supernatural gifts, human nature remained intact and could still do moral good. Later, this belief resurfaced in humanism, Enlightenment thinking, and theological liberalism.
Thinkers like Rousseau and Ritschl claimed that humans are naturally good, and sin is simply the result of bad influences or social corruption.
But such views ignore the clear and repeated testimony of Scripture and experience. The Bible teaches that we are sinful from birth (Ps.
51:5), that our hearts are corrupt (Jer. 17:9), and that we cannot change ourselves without divine grace. Even children, though immature, show selfishness, pride, disobedience, and deceit from a very early age. The seeds of sin are present long before the will is fully developed.
The Pelagian idea that some people can live without sin has no biblical or experiential basis. Even the godliest believers in Scripture confess their sins and shortcomings. Anyone who claims to be without sin deceives themselves (1 John 1:8). Sin is not something we first learn by imitation; it's something we're born with. It's not just what we do—it's who we are apart from God's grace.
Semi-Pelagianism After the church rejected Pelagianism, which denied original sin, a more moderate view called Semi-Pelagianism emerged. This view
agrees that Adam's fall had effects on his descendants but downplays the seriousness of those effects.
According to Semi-Pelagianism, Adam's sin did not bring guilt to the human race, but rather a kind of moral weakness. Humans were not made sinful, but sick. Our wills are now inclined toward evil, and while we cannot live without sin, we still have the ability to choose good. Once a person chooses what is right, God's grace comes to help complete it.
This view was embraced by the Eastern (Greek) Church and increasingly by the Western Church. The Council of Trent taught that although human freedom was damaged by the fall, it wasn't destroyed. Desire (concupiscence) was seen as a weakness, but not sinful in itself.
Many others throughout church history have held similar views— including some Anabaptists, Zwingli, the Remonstrants, and even modern liberal theologians. They all agree that Adam's sin passed on weakness but not guilt, and that people are only condemned for their own choices. Original sin, they say, might lead to sin, but it isn't truly sin.
Critique of Semi-Pelagianism Here is why this view is deeply flawed:
1. It downplays the seriousness of sin.
The Bible says that sin is lawlessness (1 John 3:4). Every human being is either in a state of obedience to God's law or disobedience. There's no middle ground. If we're born into a state that doesn't fully match God's law, then it is sinful. Calling
this condition a "sickness" or "weakness" is a way of avoiding the truth. Scripture doesn't separate sin from guilt—where there is sin, there is guilt (James 2:10; Gal. 3:10).
2. It leads to contradictions.
If our sin nature leads to death (Rom. 6:23), separation from God, and a life full of other sins, how can it not itself be sin? If the tree is good, why does it bear bad fruit? If the stream is pure, why is the water dirty?
3. It misunderstands the will.
Semi-Pelagianism claims we only become guilty when our will agrees with sinful desires. But this doesn't hold up. Is our will completely unaffected by the sinful nature? If not, then the will itself is corrupted. And if our sinful choices begin when we're too young to understand what we're doing, how can we be guilty only at that moment?
4. It fails to deal with the real issue.
Everyone agrees that sin is universal. Even Semi-Pelagians admit that every human being eventually commits sin. They deny that we inherit guilt, but they cannot explain why all people—not some, but all—do in fact sin and deserve judgment.
Why does God allow every child to be born in such a condition if that condition is not truly sinful? If it leads all to ruin and some to eternal judgment, how is that just?
Semi-Pelagianism ends up using weak language about "free will" to cover over a serious theological and moral problem—and offers no real solution.
Original Sin and Concupiscence
Paul teaches that death came into the world through the sin of one man, Adam, and that this death spread to all people (Rom. 5:12). It took time for the church to fully grasp this truth, but early Christian writers began to see the connection. Irenaeus wrote that in Adam we disobeyed, but in Christ we are made obedient. Tertullian saw sin as rooted in a defect passed down from Adam. Ambrose strongly emphasized that in Adam's fall, all fell.
However, it was Augustine who most clearly built upon Paul's teaching. He often cited Romans 5, 1 Corinthians 15, and Ephesians 2 to show that all people are born in a state of sin and guilt. Augustine also appealed to infant baptism as proof of original sin: why baptize infants unless they need cleansing from sin? Moreover, he pointed out the misery and suffering of human life from birth to death—how could a just and good God subject people to such judgment unless they were guilty from the beginning?
For Augustine, Adam wasn't just an individual—he represented all humanity. All people were "in Adam," just as the Israelites were said to be "in Abraham" when he acted (Heb. 7:10). Adam's sin was passed down to us not just by example, but by inheritance. Though
Augustine didn't settle the question of how this connection works— whether we were physically or legally united with Adam—he insisted that Adam's sin was also our sin. It was both "another's and ours."
We didn't personally commit it, yet in some way we participated in it.
This sinful condition is expressed in what Augustine called concupiscence—a term he used broadly to describe all the disordered desires of our fallen nature. Most often, he focused on sexual desire, especially the involuntary movements of the body, as a visible sign of our loss of control and the presence of shame. This, for him, was a vivid illustration of the inner corruption we all carry.
Because of this, all people are born sinful, helpless to avoid sin, and in need of salvation. Even infants, if they die without baptism, are lost—not because of anything they have done, but because of the guilt inherited through Adam. Baptism removes the guilt, though not the presence of sin, which continues to war within us.
Roman Catholic Development While Roman Catholic theology built on Augustine's ideas, it gradually altered them. The central idea—that Adam's sin brought guilt and punishment to all humanity—remained. But later theologians shifted the emphasis.
They introduced the idea of a supernatural gift that God had added to human nature. When Adam sinned, he lost this gift (often called "original righteousness"), and that loss, not concupiscence itself, was seen as the essence of original sin. The inordinate desires that followed were viewed more as a punishment than as sin itself.
This led to the view that human beings, even after the fall, retained their natural state—but without the extra grace originally given.
Some theologians went so far as to say that people after the fall are essentially the same as Adam before the fall, just without the supernatural benefits. In this view, original sin isn't really a corruption of our nature, but merely the absence of a gift we once had. Concupiscence (or sinful desire) remains, but is no longer seen as truly sinful—just a weakness or tendency.
The Council of Trent adopted this more cautious language. It affirmed that Adam's sin brought guilt and sin into the world, passed down not by imitation but by birth. But it also said that concupiscence remaining after baptism is not sin in itself, only
something that leads to sin. Free will was said to be wounded, not destroyed, and could still produce naturally good actions.
As a result, the doctrine of original sin in Roman Catholic theology became largely negative: a loss of grace, not a positive corruption of nature. This weakened the seriousness of sin. For them, salvation was mainly the restoration of what was lost—grace added back through baptism and the sacraments.
Even among Roman theologians, debates continued: Was Adam's guilt imputed to us because of a physical connection (like a shared nature) or because he was our covenant head? Some said both. But the focus remained on loss, not deep moral corruption.
Editorial Reflection: Why This Matters At the heart of this debate is how we understand human nature, sin, and grace. Is sin merely weakness? Or is it guilt and rebellion before a holy God?
Augustine—and the Reformed tradition that followed him— recognized that sin is not just the absence of something good, but the presence of something twisted. We are not just deprived of righteousness—we are inclined to evil (Rom. 3:10–18). We do not merely need help; we need regeneration (John 3:3), a new heart
(Ezek. 36:26), and a perfect Mediator (Heb. 7:25).
The modern temptation, like the medieval one, is to soften sin in order to make grace seem less offensive. But in doing so, we end up with a shallow view of salvation—and of the Savior. If we are not truly lost, then Christ is not truly necessary. But if sin really does
enslave and condemn us from birth, then Christ becomes not just helpful, but our only hope.
Only when we see how deep the problem goes will we truly rejoice in the depth of God's mercy.
Total Corruption The Protestant Reformation strongly rejected the Roman Catholic tendency to downplay the seriousness of original sin. Roman theology increasingly taught that sin was merely the loss of something good—specifically, the loss of "original righteousness"— but not necessarily the presence of something evil. The Reformers insisted that original sin is not only a loss, but also a deep and total corruption of our entire nature.
Early on, this inner corruption was still referred to as "concupiscence"—a word meaning disordered desire. But unlike
Augustine, who focused on the sex drive, the Reformers applied the term to all the disordered desires in both the higher and lower parts of our being—our minds, wills, and emotions.
Calvin emphasized this vividly: it's not enough to say we've lost original righteousness. Our nature isn't just empty of good—it's full of evil. He wrote that everything in us, from the mind to the flesh, is infected with sin. In his words, "the whole man is of himself nothing but concupiscence." Sin doesn't begin only when the will agrees to temptation—it is present in its first stirrings. Even our involuntary inclinations are sinful.
The Reformers also affirmed that because of this corruption, we are by nature incapable of any true spiritual good, inclined to all
evil, and, on this basis alone, deserving of God's eternal judgment.
Though the Reformers spoke with clarity, some expressions— particularly among the Lutherans—went too far and caused confusion. Some described original sin as part of our very substance or essence, which made it sound like human nature itself was evil in its being. The Reformed, particularly Calvin, rejected this kind of language, insisting that while human nature is deeply corrupted, it is not destroyed or essentially evil.
The Reformed view taught that original sin involves both:
1. The imputation of Adam's sin to all his descendants, making us guilty before God.
2. The corruption of our nature, inherited from Adam, which results in our personal sin and spiritual death.
This understanding was once held widely, but over time, various theologians began to drift from it. Some proposed that Adam's guilt is only imputed to us because we're already born sinful, rather than the other way around. This view gained traction in many places and eventually weakened the Reformed consensus.
Yet the truth of original sin has not disappeared. Even apart from theology, the idea that we are born into a corrupt and broken condition finds support in philosophy, psychology, and science.
The solidarity of the human race, the generational patterns of sin, and the moral struggles of every age testify to a deeply flawed human nature.
Despite modern attempts to soften or deny it, the doctrine of total corruption remains as relevant and urgent as ever. Only when we grasp the depth of our fallen condition can we truly understand the greatness of Christ's redeeming work. His grace does not merely repair a weakness—it raises the dead and makes new creatures out of sinners.
Explaining Original Sin: Human Solidarity The doctrine of original sin is one of the most serious and yet most difficult truths in all of theology. It is simple to mention in a sermon, but deeply mysterious when you try to understand it fully. As Pascal once said, this truth is so hard for our minds to grasp, yet without it, we cannot even begin to understand ourselves.
Original sin refers to more than just the first sin ever committed—it is the corruption of our nature, inherited from Adam, which is the root of all the sins we commit. It is "original" not because it was part of our creation, but because it is there from the beginning of our lives, passed down to every human born after Adam.
But how can Adam's sin affect all of us? Why are we all born sinners because of something someone else did long ago? Scripture teaches clearly that sin and death entered the world through one man's disobedience (Romans 5:12; 1 Corinthians 15:22), and we see the evidence of that every day—in our brokenness, in our desires, and in the universal reach of death.
This reality can only make sense if Adam represented all humanity.
The Bible presents Adam not as an isolated individual, but as the head of the entire human family. He was our root—our natural head
—so that when he fell, we all fell in him. His sin was counted as ours because we were united to him as our representative.
This idea of human unity is essential. Unlike angels, who were created individually and judged on their own, humans were created as a race—a family connected by birth. That physical connection is vital to understanding how sin passes from Adam to us. But even more important than physical descent is the covenant God made with Adam. Adam didn't just sin on his own; he sinned as our federal head. Just as Christ obeyed for all who belong to Him, Adam disobeyed as the representative of all who descend from him.
Still, this connection isn't easy to grasp. If we say that Adam's sin is literally our own action—because we were physically in him—we end up with problems. For example, why then aren't we guilty of every sin our ancestors committed? And why was Jesus, who was also born of a woman, not guilty of original sin?
So we must understand that Adam represented us in a covenant arrangement. In this sense, we didn't personally commit Adam's sin, but God counted it as ours because Adam stood in our place. This is similar to how Christ's obedience is counted as ours—not because we performed it ourselves, but because He acted on our behalf.
This idea of representation is deeply rooted in how God has created human society. In many ways, we see people affected by the actions of others—children suffer from their parents' mistakes, citizens bear the consequences of a ruler's choices, and students are shaped by their teachers. This isn't unfair; it's simply how life works. We enjoy blessings passed down to us—education, freedom, culture, faith— without earning them. But we also inherit burdens—conflict, poverty, brokenness—that we didn't choose.
God's Word shows us that this law of solidarity applies in the moral and spiritual realm as well. We are not just isolated individuals—we are bound together. That's why Scripture speaks of God visiting the iniquity of fathers on their children (Exodus 20:5), and why the prophets lament the sins of their nation as if they were their own.
But the story doesn't end there. God's grace allows us to break from the sinful patterns of our forefathers. A new beginning is possible through repentance and faith. In this way, God affirms both our connection to others and our personal responsibility before Him.
Adam and Christ are the two most important representatives in human history. Only they stand at the head of the entire human race.
Adam brought sin and death; Christ brings righteousness and life.
They are not merely examples; they are heads of covenants—Adam of the covenant of works, Christ of the covenant of grace.
Because God's plan was not just for scattered individuals, but for humanity as His image, He ordained that the entire race would stand or fall in one person. We all fell in Adam—and all who trust in Christ are raised in Him. "For God has consigned all to disobedience, that He may have mercy on all" (Romans 11:32).
Sin as Sin's Consequence Because all of humanity is counted guilty in Adam, everyone is also born into a sinful condition. The corruption of our nature—the sin we inherit—is a consequence of the guilt we bear in Adam. In other words, original pollution flows from original guilt. This view goes back to Augustine, and although it was opposed by Pelagians and later Remonstrants, it is firmly rooted in Scripture.
The Bible often describes further sin and spiritual hardness as God's judgment on earlier sin (see Romans 1:24–28; 2 Thessalonians 2:11–
12; and many Old Testament examples). This doesn't mean God causes sin, but that in His justice, He allows sin to deepen its grip on the sinner. Sin has a tragic momentum—those who sin become more entangled in it. One sin leads to another, and each one makes the heart colder, darker, and more resistant to the light.
Adam's fall illustrates this truth in its most foundational form. His first sin did not leave his nature untouched. It was not a neutral act with no lingering effects. Rather, that sin brought about a radical inward change—shame, fear, guilt, and alienation from God. From that point forward, sin did not simply happen; it flowed out of a corrupted nature.
This reminds us of a deep and sobering reality: our actions shape us.
A single sinful choice can change the direction of our lives. Sins become habits, habits form character, and character becomes a person's path. Sin never leaves us as it found us. In Adam's case, his disobedience not only resulted in guilt but also transformed his nature—and ours—with devastating consequences.
But the sinful act of eating the forbidden fruit was not just a momentary mistake. It flowed from an inner rebellion already stirring in the heart: doubt, pride, and desire. The outward act revealed an inward rupture. The sin did not begin with the hand, but with the heart. Therefore, guilt and corruption are not two separate results—they are two sides of the same spiritual tragedy.
This corruption was not the result of some evil substance added to Adam or some good thing removed. Instead, Adam himself turned away from God, stepped outside the circle of His blessing, and began
using his God-given gifts against the very Giver. The light of fellowship was gone—and darkness entered in.
And so it is with every one of Adam's descendants. We are born in the same guilty and corrupt condition into which Adam fell.
Scripture, experience, and history all confirm this. Human nature is not morally neutral—it is fallen.
Still, we must guard against two mistakes:
1. Some say Adam's sin was only in the outward act— eating the fruit. But Scripture shows that sin was already present in his thoughts and desires. The serpent's temptation worked on the mind and heart before it reached the hand.
2. Others reverse the order—claiming we are corrupted first, and then counted guilty later only if we choose sin ourselves. But this turns guilt into something optional. It would mean sin only becomes real when we personally agree with it. That's not what
Scripture teaches.
Instead, the Reformed view holds that we are guilty in Adam, whether we feel it or not. God has judged humanity in Adam's one trespass. That judgment includes the corruption of nature and the sentence of death. Adam's sin is not just an ancient event—it is ours.
His guilt is imputed to us, and as a result, we are born already separated from God and bent toward evil.
Romans 5:16 teaches that God's one judgment (κρίμα) on Adam's one sin brought condemnation (κατάκριμα) not just to Adam, but to all his descendants. As Adam became guilty, polluted, and subject to death, so too do we all. His fall has shaped us all—from the inside out.
Inherited Sin?
How does Adam's sin become our sin? Scripture teaches that it's not simply by imitation—we aren't just copying Adam's bad example.
Instead, we inherit a sinful condition from him through our natural connection to him and by God's just judgment. Because Adam represented us, his guilt is counted as ours, and we are born already corrupted and spiritually dead.
This is true from the moment of conception. We don't become sinners only after committing our own sins; we are sinners by nature.
The clearest proof is death, which affects not just adults, but also infants and even the unborn. And death, according to Scripture, is
"the wages of sin" (Romans 6:23). It's not a natural part of life—it's a penalty.
While earlier generations often denied this, saying humans are naturally good and only corrupted by society, more recent thinking ironically echoes the biblical view in a different way. Many now say that people are fundamentally driven by instinct—beasts at heart.
Culture, education, and law restrain these animalistic tendencies, but they don't remove them. In this view, vice is inborn; virtue is learned.
Science, especially in the 19th century, began to emphasize heredity —the idea that traits, good and bad, are passed down from parents to children. We see this in families: children resemble their parents not only in appearance, but also in temperament, talents, and even weaknesses. Physical features, mental tendencies, strengths and diseases often run in families. These patterns are so common that they're reflected in sayings like, "Like father, like son."
Yet this isn't the whole picture. As much as children inherit traits, they also differ from their parents. We see constant variation. No two siblings are exactly alike. Traits may skip generations or appear unpredictably. And scientists now recognize that heredity alone can't explain everything. Environment, choices, and mysterious factors all play a role. Theories that tried to reduce humans to mere products of biology—like Lombroso's idea of a "born criminal"—have since been rejected.
Furthermore, while some traits or diseases may be passed down, not every child inherits them. In many cases, new factors—like the mixing of two lineages or healthy decisions—can bring healing and renewal. There is such a thing as regeneration in nature, not just degeneration.
So while heredity is real, we are not simply the sum of our ancestry.
We are not trapped. We are persons—created with minds, wills, and the capacity to make choices. We are moral beings, responsible for what we do. While our nature is affected by Adam's fall, we are not robots or animals driven only by instinct. We are accountable before God.
In light of this, we can affirm the reality of inherited sin without falling into despair or fatalism. Scripture teaches that while Adam's guilt and corruption are passed down to all, each person is still a responsible agent. Our sinful state is not something forced on us from the outside, but a reality that emerges from within us from the moment of our existence. "We are by nature children of wrath"
(Ephesians 2:3).
Even the regenerate—those made new by the Spirit—still pass on sinful nature to their children. As Augustine said, "The righteous do
not generate from the source from which they themselves were regenerated, but from that from which they were generated."
Original sin, then, is not simply a biological or psychological condition. It is a moral and spiritual corruption that begins with separation from God. When Adam sinned, God withdrew His fellowship. That same spiritual distance marks the beginning of every human life. God is not the author of our sin, but in His justice, He permits that those born of Adam are born in a state of guilt and pollution.
Thus, every person is both connected to Adam and responsible for his or her own sin. Each person is the true source and author of his or her own original sin.
No Exceptions Original sin is not a random condition but a part of human nature itself. All who share in human nature are touched by it. As one early theologian put it: "In Adam, the person corrupts human nature; in all others, the corrupted nature corrupts the person."
This means that sin isn't something we learn by imitation alone—it's something we inherit. Every human being is born a sinner. Scripture confirms this again and again, and so does our own experience. No people, culture, or religion has ever produced someone who lived entirely without sin.
The only exception is Jesus Christ. He alone was sinless—not because He was simply a good man, but because He is the Son of God, miraculously conceived by the Holy Spirit, the second Adam, the head of a new covenant.
But the Roman Catholic Church teaches that there is another exception: Mary, the mother of Jesus. Over time, Roman
Catholic theology came to teach three privileges about her:
1. She was free from original sin (the immaculate conception), 2. She never committed any actual sin, and 3. She was assumed into heaven without dying.
The doctrine of the immaculate conception, officially declared by Pope Pius IX in 1854, claims that Mary was preserved from original sin from the very first moment of her life, as a special act of God's grace based on Christ's future merits.
But this teaching has no foundation in Scripture. Even Aquinas admitted that the Bible says nothing about Mary being made holy in the womb. So Catholic theologians have reached for many obscure and symbolic texts to support the idea—verses from Genesis, the Psalms, the Song of Songs, and even Revelation—but none of them speak clearly about this. These strained interpretations only serve to mask the lack of solid biblical evidence.
The Bible is very clear: all have sinned, and it never makes an exception for Mary. She herself rejoices in God her Savior (Luke
1:47), which makes no sense if she had no sin to be saved from.
Scripture honors her—not for her sinlessness—but for her unique role as the mother of Jesus. Yet even that role is secondary to those who do the will of God (Matt. 12:50).
The early church fathers, like Irenaeus, Tertullian, and Origen, also never taught that Mary was sinless. On the contrary, they often spoke of her in the same way they did other believers—as someone
who sinned daily and needed grace. Catholic scholars today admit that this was the common view in the early centuries. At most, it was believed that God may have kept Mary from actual sins as a gift of grace—but not that she was preserved from original sin from the beginning.
The turning point came with the medieval theologian Duns Scotus, who argued that since God is able to do it, and since it would be fitting for Mary to be sinless, then it is likely that God did this for her. But this is not exegesis; it is speculation. The doctrine doesn't arise from the teaching of Scripture or the witness of the early church, but from a theological guess based on what seemed fitting or appropriate. In short: Mary must be sinless, because it would be improper if she were not—even if the Bible never says so.
But Scripture is our only final authority. And it testifies with one voice: there is no one righteous, not even one—except
Christ.
Total Depravity Original sin doesn't just affect humanity as a whole—it corrupts each person completely. It reaches every part of who we are: our minds, our hearts, our wills, our consciences, our bodies, and our emotions.
Scripture says that from youth, our hearts are inclined toward evil (Gen. 6:5; Ps. 51:5). We can't renew ourselves, understand God's truth, or obey His law in our natural condition (1 Cor. 2:14; Rom.
8:7; Eph. 2:1). Jesus said we must be born again to see the kingdom of God (John 3:3). Salvation is entirely a work of God's grace—from beginning to end.
Augustine, and later the Reformers, understood this well. Because Adam's sin ruined human nature, nothing truly good can come from us apart from grace. A bad tree cannot produce good fruit. We sin not just by choice but by nature. We are no longer able not to sin.
Even what appears virtuous in us is often rooted in pride, selfishness, or love of human approval rather than love for God.
This is a hard teaching, and it's often misunderstood. But when rightly explained, it matches what we see in ourselves and the world.
1. Not That All Sins Are Always Committed The Bible doesn't say that every person commits every possible sin at all times. Rather, it teaches that the root of our nature is turned away from God. We're not neutral. We are either oriented toward God or away from Him. There is no middle ground. A person who breaks one commandment is guilty of breaking them all (James 2:10). A truly good person would keep all of God's commands, not just some.
We are, at the core, either in rebellion or in submission. Scripture declares we are in rebellion.
2. Not That We Are No Longer Human Sin is not something physical or part of our essence. We are still human after the fall. We still have reason, conscience, and will. We can do things that are outwardly good and admirable. Augustine called the virtues of unbelievers "splendid vices," because even noble actions, if not done in faith and for God's glory, fall short of true righteousness. Calvin himself often pointed to the honorable deeds of unbelievers as things Christians should imitate.
So when we speak of total depravity, we don't mean that people are as bad as they could possibly be. God restrains evil in many ways— through conscience, society, laws, and even common grace. People may love their families, seek justice, or show compassion. But the heart behind those actions is still corrupted. The source—the spring
—is unclean, and thus even the clearest water is tinged with sin.
3. A Will That Cannot Want Good Total depravity doesn't mean we are forced to sin against our will.
Rather, our wills are free, but they are free in the wrong direction.
We now freely want what is evil and resist what is good. We sin willingly, not by external compulsion. The will still functions, but its compass is broken.
Some theologians, like Jonathan Edwards, distinguished between "natural" and "moral" inability. He said we have the natural faculties to obey God but lack the moral ability—the love, desire, and inclination to do so. While this is helpful, it can cause confusion. The Reformed tradition generally preferred the term natural inability, because our inability to love God is not just a moral problem—it's part of our fallen condition. It comes from within and marks all who are born in Adam.
4. God's Law as the True Standard What does "good" really mean? In everyday life, we call many things
"good": a generous neighbor, a loving parent, a kind stranger. But God's law is the true and perfect standard. And that law demands more than outward actions—it demands pure motives, done in faith, and for God's glory (Rom. 14:23; 1 Cor. 10:31).
By this standard, who can stand? Even our best works fall short. We do not naturally love God with all our heart, soul, and strength. So when Scripture says, "There is no one who does good, not even one"
(Ps. 14:3), it is not exaggerating. It is speaking from God's perspective.
Some, like Rome or parts of Lutheranism, have tried to divide the human person—saying we are unable to do good in spiritual things, but able in natural things. But Scripture doesn't support that division. Our whole nature is meant to glorify God, in everything we do. If we are not doing that, then our "good" works are still tainted with sin.
Even the World Knows the Problem If someone doesn't believe the Bible's diagnosis, they need only listen to what the great thinkers of history have said. Philosophers and moralists throughout the ages have testified to the darkness within humanity. Pascal, Hobbes, Kant, and others all concluded that people are selfish, deceitful, and prone to evil.
They observed what Scripture had already revealed: beneath the surface of civility is a sinful heart, restrained only by laws, fear, and societal norms. Remove those restraints, and human corruption spills out. History confirms it. So do our own hearts.
Yet while the world sees this problem, it has no solution. Its diagnosis is severe, but its medicine is weak or cruel. Philosophy may describe the fall, but it cannot offer redemption.
Only God, in Christ, condemns sin while offering grace. When He tells us the truth about ourselves, it is not to shame or cast us off, but
