Tractates on the Gospel of John

³ Yet because He appeared as it were in the night, in a mortal body, He lighted for Himself a lamp by which He might be seen. That lamp was John, concerning whom you lately heard many things: and the present passage of the evangelist contains the words of John; in the first place, and it is the chief point, his confession that he was not the Christ. But so great was the excellence of John, that men might have believed him to be the Christ: and in this he gave a proof of his humility, that he said he was not when he might have been believed to have been the Christ; therefore, “This is the testimony of John, when the Jews sent priests and Levites to him from Jerusalem to ask him, Who are you?” But they would not have sent unless they had been moved by the excellence of his authority who ventured to baptize. “And he confessed, and denied not.” What did he confess? “And he confessed, I am not the Christ.”

4. “And they asked him, What then? Are you Elias?” For they knew that Elias was to precede Christ. For to no Jew was the name of Christ unknown. They did not think that he was the Christ; but they did not think that Christ would not come at all. When they were hoping that He would come, they were offended at Him when He was present, and stumbled at Him as on a low stone. For He was as yet a small stone, already indeed cut out of the mountain without hands; as says Daniel the prophet, that he saw a stone cut out of the mountain without hands. But what follows? “And that stone,” says he “grew and became a great mountain and filled the whole face of the earth.” Mark then, my beloved brethren, what I say: Christ, before the Jews, was already cut out from the mountain. The prophet wishes that by the mountain should be understood the Jewish kingdom. But the kingdom of the Jews had not filled the whole face of the earth. The stone was cut out from thence, because from thence was the Lord born on His advent among men. And wherefore without hands? Because without the cooperation of man did the Virgin bear Christ. Now then was that stone cut out without hands before the eyes of the Jews; but it was humble. Not without reason; because not yet had that stone increased and filled the whole earth: that He showed in His kingdom, which is the Church, with which He has filled the whole face of the earth. Because then it had not yet increased, they stumbled at Him as at a stone: and that happened in them which is written, “Whosoever shall fall upon that stone shall be broken; but on whomsoever that stone shall fall, it will grind them to powder.” At first they fell upon Him lowly: as the lofty One He shall come upon them; but that He may grind them to powder when He comes in His exaltation, He first broke them in His lowliness. They stumbled at Him, and were broken; they were not ground, but broken: He will come exalted and will grind them. But the Jews were to be pardoned because they stumbled at a stone which had not yet increased. What sort of persons are those who stumble at the mountain itself? Already you know who they are of whom I speak. Those who deny the Church diffused through the whole world, do not stumble at the lowly stone, but at the mountain itself: because this the stone became as it grew. The blind Jews did not see the lowly stone: but how great blindness not to see the mountain!
