Commentary on 1 John
Andreas of Caesarea
John says this with reference to the close union of the Word with the flesh. Or perhaps he says this with reference to the resurrection, considering the way in which it was made known to the apostles by the action of Thomas. That proved that Christ rose again with the same flesh in which he had been crucified.
What did they proclaim, but that eternal life has appeared to us and that we have become witnesses of it? What you gain from this proclamation is the right to share this experience with us. For the one who is in fellowship with us has fellowship with the Father and with his Son, Jesus Christ, and since you share in the same fellowship, we shall all have joy together, in that we have been united to God.
What is this message? It is that eternal life has appeared to us. For the Father so loved the world that he gave his only-begotten Son, and this is what we proclaim to you—that the Word of God who has come into the world and become a man is both God and light.
John says that if we sin we have no fellowship with God, but if we do the works of light, then we have fellowship with one another.
