Why did the evangelist say that this took place in Bethany? In order to show the boldness of the great preacher, that he preached thus about Christ not in a house, not in a corner, but at the Jordan, amidst a multitude of people. It is necessary, however, to know that in the most accurate manuscripts it reads: in Bethabara. For Bethany is not on the other side of the Jordan, but near Jerusalem.
Jn. 1:29. The next day John sees Jesus coming toward him and says: Behold the Lamb of God, who takes upon Himself the sin of the world.
The Lord often comes to the Forerunner. Why is this? Since the Lord was also baptized by John, as one of many, He often comes to him, no doubt, so that some would not think that He was baptized on equal terms with the rest as one guilty of sins. The Baptist, wishing to correct such an assumption, says: "Behold the Lamb of God, who takes upon Himself the sin of the world." He who is so pure that He takes upon Himself and destroys the sins of others clearly could not have received the baptism of confession (repentance) on equal terms with the rest.
Examine, I ask you, this expression as well: "behold the Lamb of God." This word is addressed to those who desire to see the Lamb of whom Isaiah proclaims (Isa. 53:7–8). "Behold," he says, "that Lamb whom they seek; that Lamb is right here." For naturally, many who had diligently studied the prophetic book of Isaiah were occupied with the question of who that Lamb might be. So John points Him out. He did not say simply "a lamb," but "that Lamb," for there are many lambs, just as there are many christs; but He is that Lamb whose type was set forth by Moses (Exod. 12) and of whom Isaiah proclaims (Isa. 53:7–8).
Christ is called the "Lamb of God" either because God gave Him over to death for us, or because God accepted Christ's death for our salvation. Just as we commonly say "this is the sacrifice of so-and-so," instead of saying "so-and-so offered this sacrifice," so too the Lord is called the Lamb of God because God the Father out of love for us gave Him over to be slain for us.
John did not say "took away" sin, but "takes away," because He takes upon Himself our sins every day, some through baptism, others through repentance. The lambs that were slain in the Old Testament did not perfectly destroy a single sin; but this Lamb takes away the sin of the whole world, that is, destroys and blots it out. Why did John not say "sins," but "sin"? Perhaps because, by saying "sin," he spoke of all sins in general; just as we usually say "man" fell away from God, instead of "all mankind," so he here, by saying "sin," indicated all sins. Or perhaps because the sin of the world consisted in disobedience, since man plunged into passions through disobedience to God, and the Lord blotted out this disobedience by being obedient unto death and healing the opposite with the opposite.
Jn. 1:30. This is He of whom I said: after me comes a Man who has been placed ahead of me, because He was before me.
Above, John says to those who came from the Pharisees: "There stands among you One whom you do not know, but Who takes precedence before me" (Jn. 1:26–27), and now he also points Him out with his finger and declares to those who do not know, saying: "This is the One about whom I testified before the Pharisees, that He takes precedence before me, that is, He surpasses me in dignity and honor." Why? Because He was before me. Listen, Arius. John did not say of Christ "created before me," but "was." Listen also, you sect of the Samosatene. The Lord did not begin His existence from Mary, but was before the Forerunner by His pre-eternal existence. For if the Lord, as you idly babble, received the beginning of His existence from Mary, how could He have been before the Forerunner? And the Forerunner, as everyone knows, came into the world six months before the Lord's birth in the flesh.
He is called "a Man" perhaps because He had reached full maturity, for He was baptized at thirty years of age, or perhaps in the sense that He is the Husband of every soul and the Bridegroom of the Church. For the apostle Paul says: "I betrothed you, to present you to one Husband, namely Christ" (2 Cor. 11:2). So too the Forerunner says: "I am only the friend of the Bridegroom and mediator, but the Husband comes after me; I draw souls to faith in Christ, and He is the Husband who will be united with them."
Jn. 1:31. I did not know Him; but for this reason I came baptizing in water, that He might be made manifest to Israel.
Since the Forerunner was a relative of the Lord (for the angel says to the Virgin: "Behold, Elizabeth your 'kinswoman' has conceived" (Luke 1:36)), lest anyone think that the Forerunner was favoring the Lord and giving such lofty testimony about Him because of his kinship with Him, he often says: "I did not know Him," and thereby removes the suspicion.
"But for this reason I came baptizing in water, that He might be made manifest to Israel," that is, so that all might come to faith in Him and He might be made manifest to the people, for this reason I baptize; for when I baptize, the people flock together, and when the people gather, then I also proclaim to them about Christ in my preaching, and He Himself, being in plain sight, is present before them. For if people had not come for baptism, how would John have made the Lord manifest to them? He would not have gone from house to house, leading Christ by the hand and pointing Him out to everyone. Therefore he also says: "I came for this reason to baptize in water, that He might be made manifest by me to the people who come for baptism."
From this we also learn that the miracles attributed to Christ in His childhood are false and were composed by those who wished to mock the mystery. For if they were true, how could they not have known the Lord who performed them? At the very least, it is unnatural that such a Wonderworker would not have been spoken of everywhere. But this is not so, no. For before His baptism, the Lord neither performed miracles nor enjoyed renown.
Jn. 1:32. And John bore witness, saying: I saw the Spirit descending from heaven like a dove, and remaining upon Him.
Jn. 1:33. I did not know Him; but He who sent me to baptize in water said to me: "Upon whom you see the Spirit descending and remaining upon Him, that is He who baptizes with the Holy Spirit."
"But He who sent me to baptize in water said to me: 'Upon whom you see the Spirit descending and remaining on Him, He is the one who baptizes with the Holy Spirit.'" John, deflecting, as I said, suspicion from his own testimony about Christ, traces this testimony back to God the Father. "I," he says, "did not even know Him, but the Father revealed Him to me at the baptism."
"But," someone may ask, "if John did not know Him, how does the evangelist Matthew (Matt. 3:14) say that he tried to prevent Him and said, 'I need to be baptized by You'?" To this one may answer that the words "did not know Him" should be understood to mean that long beforehand and before the baptism, John did not know Him, but then, at the time of the baptism, he recognized Him. Or one may answer differently: although John knew about Jesus, that He was the Christ, that He would baptize with the Holy Spirit he learned only then, when he saw the Spirit descending upon Him.
So, by the words "I did not know Him," John gives us to understand that although he did not know that He would baptize with the Holy Spirit, he did know that He was superior to many. That is why, knowing surely that He was greater than all, John, according to the evangelist Matthew, tried to prevent Him. But when the Spirit descended, he came to know Him even more clearly and proclaimed Him to the rest.
And the Spirit appeared to all those present, and not to John only. "Why then," someone will say, "did they not believe?" Because their foolish heart was darkened so that, even seeing Him working miracles, they did not believe. Some, however, say that not all saw the Spirit, but only the most devout. For although the Spirit descended in a sensible form, it was fitting for Him to appear not to all, but to the worthy, since the prophets too, for example Daniel and Ezekiel, although they saw many things in sensible form, yet no one else saw those things.
Jn. 1:34. And I saw and bore witness that this is the Son of God.
Where then did John testify about Jesus that He is the Son of God? This is nowhere written. He calls Him the Lamb, but nowhere the Son of God. From this it is natural to suppose that very much else was also left unrecorded by the apostles, for not everything was written down.
Jn. 1:35. On the next day John was standing again, and two of his disciples.
On account of the fickleness of his listeners, John is compelled to repeat the same things, so that at least by continuous testimony he might accomplish something. And he was not deceived in this; but he brought two disciples to Christ.
Being a true groomsman, he did everything to bring human nature to her bridegroom. For this reason Christ, as the bridegroom, is silent, and the mediator proclaims everything. And the Lord, as the bridegroom, comes to the people. At weddings it is customary for the bride not to come to the bridegroom, but the bridegroom to the bride, even if he be a king's son. So too the Lord, desiring to betroth our nature to Himself, came down to her on earth Himself, and when the marriage was accomplished, He took her with Him when He ascended to the house of His Father.
Jn. 1:36. And, having seen Jesus walking, he said: behold the Lamb of God.
