Doctrine That Unites
Doctrine That Unites It is a modern myth that doctrine divides and love unites. The opposite is true. Real love is built on real truth, and real unity is built on real doctrine.
Paul did not tell the Ephesians to keep unity by ignoring doctrine. He told them to keep the unity of the Spirit through the bond of peace, and then he defined that unity with seven doctrinal statements: one body, one Spirit, one hope, one Lord, one faith, one baptism, one God and Father of all
(Ephesians 4:4-6). Unity is not the absence of doctrine; it is the presence of shared doctrine.
The didaché unites because it centers the church on Christ. When the teaching is about Him — His person, His work, His commands — then personalities fade and preferences bow. Denominational walls are exposed as secondary, because they are. The church is not united by tradition, style, or ethnicity. The church is united by truth. Jesus prayed that His disciples would be one "so that the world may believe that you have sent me" (John
17:21). But that oneness was not generic. It was oneness in the truth:
"Sanctify them by the truth; your word is truth" (John 17:17). Truth is the instrument of unity.
Second John 1:9-10 again is instructive. The one who continues in the teaching "has both the Father and the Son." To have the Father and the Son is to be brought into the fellowship of the Trinity. That is the deepest unity possible. It is a shared life, not a shared slogan. Therefore, the didaché does not create uniformity of expression, but it creates unity of essence. We are one because we share one Lord and one faith. We can differ on many things, but we cannot differ on the person and work of Christ and still be one body.
Romans 16:17 warns us to avoid those who teach contrary to the didaché because they destroy unity. The division is not caused by the one who holds the line; it is caused by the one who crosses it. The shepherd who shuts the gate to wolves is not the divider of the sheep. The wolves are. The call to avoid false teachers is a call to protect unity. A church that tolerates error will soon be fractured by it. Heresy has never produced peace. It produces quarrels, factions, and shipwrecked faith.
True unity is also missional. The church devoted to the apostles' teaching in Acts 2 was also a church of fellowship, breaking bread, and prayer. The
result was "the Lord added to their number daily those who were being saved" (Acts 2:47). Doctrine did not hinder evangelism; it fueled it. When the church knows what it believes, it knows what to say. When the church is united on the gospel, it speaks with one voice to the world. A confused church produces confused converts. A united church demonstrates to the world that the Father sent the Son.
Titus 1:9 connects doctrine to encouragement and refutation. Both are acts of love for the body. To encourage by sound doctrine is to build up the saints in unity. To refute those who oppose it is to protect the saints from division. The elder who does both is a guardian of unity. He is not looking for fights, but he is not afraid of them. He knows that peace without truth is a false peace, and that war for truth is sometimes the only path to lasting peace.
The didaché also unites across generations and cultures. The gospel that saved Peter saves us. The Christ preached in Jerusalem is the Christ preached in every nation. The faith once for all delivered to the saints is not a Western faith or an ancient faith. It is the church's faith. When we keep the teaching, we join the communion of saints across time and space. We stand with Athanasius against Arianism, with Augustine against Pelagianism, with Luther against indulgences, with the martyrs against Caesar. We are not alone. We are part of a long line of those who held the trustworthy word.
If anyone wants to do His will, he will know whether the teaching is from God or I am speaking on My own.
John 7:17
To keep the didaché is finally to know God. That is the treasure. It is not just a system, though it is systematic. It is not just a tradition, though it is handed down. It is the revelation of the Father through the Son by the Spirit.
It is the message that saves, sanctifies, and secures. The church that guards it, devotes itself to it, discerns by it, and declares it will find that it is not a burden to carry. It is a treasure that carries us. It unites us to Christ, and in Him, to one another.
Therefore, let us hold firmly to the trustworthy word as taught. Let us continue in the teaching of Christ, that we may have both the Father and the Son. Let us watch out for what is contrary and keep away from it. Let us test all things and hold fast to what is good. And let us speak this teaching
clearly, as we should, so that the world may know that the Father sent the Son to be the Savior of the world. This is the treasure. This is the didaché .
Keep it.
