6 This is he that came by water and blood, [even] Jesus Christ; not with the water only, but with the water and with the blood
6. "This is he that came." The identity of the man of Nazareth with the eternal Son of God is again emphasized as the central truth of Christian theology, the reception of which is necessary to the attainment of victory over the world and of translation out of darkness into the marvelous light of His kingdom. Then follow the witnesses to this truth which are "the water and the blood." Many are the explanations of these words. The ritualists understand them to signify the sacraments of baptism and of the Lord's Supper. Others see only symbols of purification and redemption. But it seems to the writer that John uses these words as a summary of Christ's earthly life and mission, baptism in the water of Jordan and His sacrificial death by the shedding of His blood for the redemption of the world. The cardinal truths of His gospel are here briefly stated; for at His baptism with water was His baptism with the Holy Spirit attended by the Divine announcement of His Sonship to God in words implying that He is the Son in a sense unique and peculiar. This was a sufficient opening and explanation of the whole of His ministry. His public and tragic death is at once the close and the explanation of His life of self-sacrifice. "The Gnostic teachers, against whom the apostle is writing, admitted that the Christ came 'through' and 'in' water; it was precisely at the baptism, they said, that the Divine Word united Himself with the man Jesus. But they denied that the Divine Person had any share in what was effected 'through' and 'in' blood; for, according to them, the Word departed from Jesus at Gethsemane. John emphatically assures us that there was no such separation. It was the Son of God who was baptized; it was the Son of God who was crucified; and it is faith in this vital truth that produces brotherly love, that overcomes the world, and is eternal life."
