John 1:36

The Prophets and Apostles then all preached Him absent; the Prophets before His coming according to the flesh, the Apostles after He was taken up; John alone proclaimed Him present. Wherefore he calls himself the "friend of the Bridegroom," since he alone was present at the marriage, he it was that did and accomplished all, he made a beginning of the work. And "looking upon Jesus walking, he saith, Behold the Lamb of God." Not by voice alone, but with his eyes also he bore witness to, and expressed his admiration of, Christ, rejoicing and glorying. Nor does he for awhile address any word of exhortation to his followers, but only shows wonder and astonishment at Him who was present, and declares to all the Gift which He came to give, and the manner of purification. For "the Lamb" declares both these things. And he said not, "Who shall take," or "Who hath taken"; but, "Who taketh away the sins of the world"; because this He ever doth. He took them not then only when He suffered, but from that time even to the present doth He take them away, not being repeatedly crucified, (for He offered One Sacrifice for sins,) but by that One continually purging them.

As then The Word shows us His pre-eminence, and The Son His superiority in comparison with others, so "The Lamb, The Christ, that Prophet, the True Light, the Good Shepherd," and whatever other names are applied to Him with the addition of the article, mark a great difference. For there were many "Lambs," and "Prophets," and "Christs," and "sons," but from all these John separates Him by a wide interval. And this he secured not by the article only, but by the addition of "Only-Begotten"; for He had nothing in common with the creation.

(Hom. 1) The Lamb therefore he calls Him; for that He was about to give us freely His fleece, that we might make of it a wedding garment; i. e. would leave us an example of life, by which we should be warmed into love. (Hom. in Vigil. S. And.) The walking of Jesus has a reference to the economy of the Incarnation, by means of which He has condescended to come to us, and give us a pattern of life.

Looking he saith, as if signifying by his looks his love and admiration for Christ.

"Again," saith the Evangelist, "John stood, and saith, Behold, the Lamb of God." Christ utters no word, His messenger saith all. So it is with a bridegroom. He saith not for a while anything to the bride, but is there in silence, while some show him to the bride, and others give her into his hands; she merely appears, and he departs not having taken her himself, but when he has received her from another who gives her to him. And when he has received her thus given, he so disposes her, that she no more remembers those who betrothed her. So it was with Christ. He came to join to Himself the Church; He said nothing, but merely came. It was His friend, John, who put into His the bride's right hand, when by his discourses he gave into His hand the souls of men. He having received them, afterwards so disposed them, that they departed no more to John who had committed them to Him. And here we may remark, not this only, but something besides. As at a marriage the maiden goes not to the bridegroom, but he hastens to her, though he be a king's son, and though he be about to espouse some poor and abject person, or even a servant, so it was here. Man's nature did not go up, but contemptible and poor as it was, He came to it, and when the marriage had taken place, He suffered it no longer to tarry here, but having taken it to Himself, transported it to the house of His Father.
