Tractates on the Gospel of John

^16. My brethren, this question if solved today would oppress you, I do not doubt, for already have I spoken many words. But know that the question is of such a character that alone it is able to extinguish the party of Donatus. I have said thus much, my beloved, in order to gain your attention, as is my wont; and also in order that you may pray for us, that the Lord may grant to us to speak what is suitable, and that you may be found worthy to receive what is suitable. In the meantime, be pleased to defer the question for today. But in the meantime, I say this briefly, until I give a fuller solution: Inquire peacefully, without quarreling, without contention, without altercations, without enmities; both seek by yourselves, and inquire of others, and say, “This question our bishop proposed to us today, and he will resolve it at a future time, if the Lord will.” But whether it be resolved or not, reckon that I have propounded what appears to me of importance; for it does seem of considerable importance. John says, “I have need to be baptized by You,” as if he knew Christ. For if he did not know Him by whom he wished to be baptized, he spoke rashly when he said, “I have need to be baptized by You.” Therefore he knew Him. If he knew Him, what is the meaning of the saying, “I knew Him not: but He that sent me to baptize with water, the same said unto me, Upon whom you shall see the Spirit descending, and abiding upon Him, as a dove, the same is He which baptizes with the Holy Ghost”? What shall we say? That we do not know when the dove came? Lest perchance they take refuge in this, let the other evangelists be read, who have spoken of this matter more plainly, and we find most evidently that the dove then descended when the Lord came up out of the water. Upon Him baptized the heavens opened, and He saw the Spirit descending. If it was when He was already baptized that John knew Him, how says he to Him, coming to baptism, “I have need to be baptized by You”? Ponder this in the meantime with yourselves, confer upon it, treat of it, one with another. The Lord our God grant that before you hear it from me, the explanation may be revealed to some of you first. Nevertheless, brethren, know this, that by means of the solution of this question, the allegation of the party of Donatus, if they have any sense of shame, will be silenced, and their mouths will be shut regarding the grace of baptism, a matter about which they raise mists to confuse the uninstructed, and spread nets for flying birds.
