Often our Hindu friends claim that there is no difference between Christianity and Hinduism, and try to justify this claim by saying that the concepts of "Trinity" and "Thrimurthis," and "Incarnation" and "Avatar," are the same, or fundamentally similar and only superficially dissimilar. But is this true? Many would even be willing to accept that Jesus is one of the avatars, and some even worship Jesus along with the other gods and goddesses. But is Jesus just another avatar?
The Ten Avatars of Vishnu
Avatar (Sanskrit, "to descend into," or descent) refers to the manifestation of Vishnu — the preserver god who, along with Brahma the creator god and Shiva the destroyer god, constitutes the Hindu Thrimurthis — either in animal, human, or hybrid animal-human forms, to manifest and to establish dharma: to destroy evil and bless the righteous (Sanskrit dusta sikshana and sishta rakshana), or to destroy adharma and establish dharma. This concept is found in the Bhagavad Gita (4:6-8) and in the Puranas. Some texts suggest twenty-two avatars, but generally only ten are recognized, of which nine are in the past and one will be in the future.
The Fish (Matsya) avatar was for saving the ancient man Manu from a devastating flood by towing his boat to safety. The Tortoise (Kurma) descent was for being instrumental in providing nectar for the gods, to make them immortal. The Boar (Varaha) was for killing a demon, Hiranyaksha, and rescuing the earth when it was inundated. The Man-Lion (Narasimha) was for saving a devotee from persecution at the hands of Hiranyakashipu, the demon king and brother of Hiranyaksha, by killing him — he had received a boon from Brahma that neither man nor animal would be able to kill him, hence the hybrid form. The Dwarf (Vamana) was for getting rid of the demon king Mahabali. Parashurama, "Rama with the axe," the angry man, was for saving the Brahmin caste from the tyranny of the Kshatriyas. Rama, the perfect man, was for annihilating the demon king Ravana. Krishna, the divine statesman, was for ensuring that Arjuna would uphold his sacred caste dharma. The next is Buddha, the compassionate man — or, alternatively, Balarama, the brother of Krishna, according to some. Kalki, the man on the white horse, will come in the future, at the end of the Kali Yuga, the end of the age, after which a whole new cycle of cosmic history will begin.
Avatar and Incarnation Compared
When we contrast the concept of avatar with Christ's incarnation, it becomes crystal clear that there are fundamental differences and only superficial similarities between the two. For example, incarnation is real, historical, permanent, and a once-for-all-time act of God, whereas avatars are multiple, not historical, and not permanent. The incarnation was, and is, for the purpose of seeking and saving sinful humanity — by making the sacrifice, the atonement, once and for all, for the sins of all mankind, because all have sinned and fallen short of the glory of God — and the different avatars are for different purposes, as described above, and in the ultimate analysis their purpose is exactly the opposite. Lastly, but most importantly, none of the avatars made any unique and exclusive claims like the ones Jesus Christ made for himself — and those claims, if true, show that Jesus is not just one of many avatars, but the only true God-Man and Savior of the world.
But making claims in itself does not prove anything. So we have to see if there are any objective criteria to evaluate the claims and verify their truth.
Eight Criteria for the True God-Man
There have been some who claimed to be, and some who are claiming to be, the God-incarnate, or God in human form. But how can we know who the real God-incarnate, the real God-Man, is? It is important for us to have some criteria that will help us know who the real God-Man is among the claimants. Seekers after truth and philosophers have struggled with this issue, and have come up with some criteria which I have listed and explained below, drawing substantially on Josh McDowell's treatment of this question, together with my own study over the years (cf. Josh McDowell, The New Evidence that Demands a Verdict [Nashville: Thomas Nelson Publishers, 1999], 285-328). If God became a man, we would expect Him to fulfill eight things in His birth, life, and death.
First, have a supernatural entry into human history. Why? Because a child born naturally will be a natural human child, and cannot be looked upon as God in human form. Jesus alone had a unique entrance into human history, through virginal conception. It was foretold by the prophets (Genesis 3:15; Isaiah 7:14) and confirmed by the Gospel accounts (Matthew 1:18-25; Luke 1:26-38; 2:1-7). The virgin birth made possible the uniting of full deity and full humanity in one person, and the person born was God-Man — not just God, nor just a man. This must be the case, because only a true human can suffer and die, and only a true divine person could give that suffering infinite value. Moreover, only an infinite God could bear the full penalty for all the sins of all people; any finite creature would be incapable of bearing that penalty. So when Jesus suffered, it was God the Son who suffered on the cross, in his humanity. Also, only someone who was truly and fully God, and truly and fully human, could be the one mediator between God and man (1 Timothy 2:5).
Second, be sinless. Why? Because the one who comes to save sinners should be free from sin — just as a blind man cannot show the way to another blind man, a sinner cannot save another sinner (Psalm 49:7-9; Hebrews 9:11-28; 10:1-18). The virgin birth made possible Christ's true humanity without his inheriting the corrupt moral nature; the sin nature that could otherwise have been transmitted to Jesus from Mary was prevented by the work of the Holy Spirit (Luke 1:35). Jesus demonstrated sinlessness in his character. His sinlessness is established by the testimony of Jesus himself (John 8:29), of his friends (John 6:69; 1 Peter 2:22; 1 John 3:5; Hebrews 7:26; 2 Corinthians 5:21; Luke 1:35), and even of his enemies (Matthew 27:19, 24, 54; Luke 23:41).
Third, have an acute sense of difference from other men, who are mere men. Why? Because it would be odd for God in human form to forget that He is God, and not just a man, and then suddenly realize that He is God. Jesus demonstrated that sense of difference throughout his life in the world, in his words and deeds (Luke 2:49; John 2:13-17).
Fourth, speak the greatest words ever spoken, or teach the greatest things ever taught by any man. Why? Because the infinite wisdom of God should be reflected in His teachings, and His words should have unparalleled impact. History bears testimony to the fact that Christ's words have impacted mankind more profoundly than the words of any other person in history.
Fifth, have universal and lasting influence. Why? Because it would be odd for the God of the universe to be the god of a tribe or small group of people when He comes into human history to reveal Himself, and for His influence to be limited and temporary. Christ's influence on human history and life is universal, lasting, and unparalleled; he is the focal point of our history, and without him we cannot make sense of our history.
Sixth, satisfy the spiritual hunger of mankind universally. Why? Because if the God of the universe comes into human history to save all mankind, it would be odd for Him not to satisfy the spiritual hunger of mankind universally. Jesus has satisfied, and is satisfying, the spiritual hunger of people from every tongue and nation.
Seventh, demonstrate supernatural powers. Why? Because when the God of the universe, the Creator God, enters into the space-time universe, He should demonstrate His power over His own creation — otherwise we cannot be sure that He is the God-incarnate. Jesus uniquely demonstrated power over nature, disease, and death.
Eighth, exercise power over death. Why? Because death is the ultimate destroyer of meaning in human life, and it is a consequence of sin. So if God comes to deliver us from sin and death, and to give us hope of eternal life, He should demonstrate power over death. Jesus demonstrated his power over death when he called dead people back to life, but more importantly when he himself came back to life, resurrected, on the third day.
If God has come into the world in the form of a man, and if we are to accept the claim of a person to be the God-Man and the Savior of the world, the above eight criteria should be fulfilled in his birth, life, and death. If these eight things are not true of a person who has claimed to be, or who is believed to be, God in human form, he can be looked upon as a man only, and not as God-Man. This is like saying that if a triangle exists, it must have three sides, and the sum of its three angles must be one hundred and eighty degrees. Jesus Christ is the only one who fulfills the above criteria, and hence qualifies to be the God-incarnate.
Incarnation — the infinite, omnipotent, and eternal God the Son becoming man, and joining himself to a human nature forever — will remain for eternity the most profound miracle and the most profound mystery in all the universe (cf. Wayne Grudem, Systematic Theology [Grand Rapids: Zondervan Publishing House, 1994], 531, 563). But God has done this for us, so that we might know Him and enjoy Him forever, and the question of our final, eternal destiny is directly linked to what we do with this truth about Jesus.
