John 15:2

(ix. de Trin) The useless and deceitful branches He cuts down for burning.

"Every branch in Me that beareth not fruit the Father taketh away." Here He alludeth to the manner of life, showing that without works it is not possible to be in Him. "And every branch that beareth fruit, He purgeth it." That is, "causeth it to enjoy great care." Yet the root requires care rather than the branches, in being dug about, and cleared, yet about this He saith nothing here, but all about the branches. Showing that He is sufficient to Himself, and that the disciples need much help from the Husbandman, although they be very excellent. Wherefore He saith, "that which beareth fruit, He purgeth it." The one branch, because it is fruitless, cannot even remain in the Vine, but for the other, because it beareth fruit, He rendereth it more fruitful. This, some one might assert, was said with relation also to the persecutions then coming upon them. For the "purgeth it," is "pruneth," which makes the branch bear better. Whence it is shown, that persecutions rather make men stronger.

(Tr. lxxx. 2) He says this as being the Head of the Church, of which we are the members, the Man Christ Jesus; for the vine and the branches are of the same nature. When He says, I am the true vine, He does not mean really a vine; for He is only called so metaphorically, not literally, even as He is called the Lamb, the Sheep, and the like; but He distinguishes Himself from that vine to whom it is said, How art thou turned into the degenerate plant of a strange vine unto me. (Jer. 11:21) For how is that a true vine, which when grapes are expected from it, produces only thorns? (de Verb. Dom. serm. lix) For we cultivate God, and God cultivates us. But our culture of God does not make Him better: our culture is that of adoration, not of ploughing: His culture of us makes us better. His culture consists in extirpating all the seeds of wickedness from our hearts, in opening our heart to the plough, as it were, of His word, in sowing in us the seeds of His commandments, in waiting for the fruits of piety. (Tr. lxxx. 3) And who is there in this world so clean, that he cannot be more and more changed? Here, if we say that we have no sin, we deceive ourselves. (1 John 1:8) He cleanseth then the clean, i. e. the fruitful, that the cleaner they be, the more fruitful they may be. Christ is the vine, in that He saith, My Father is greater than I; but in that He saith, I and My Father are one, He is the husbandman; not like those who carry on an external ministry only; for He giveth increase within. Thus He calls Himself immediately the cleanser of the branches: Now ye are clean through the word, which I have spoken unto you. He performs the part of the husbandman then, as well as of the vine. But why does He not say, ye are clean by reason of the baptism wherewith ye are washed? Because it is the word in the water which cleanseth. Take away the word, and what is the water, but water? Add the word to the element, and you have a sacrament. Whence hath the water such virtue as that by touching the body, it cleanseth the heart, but by the power of the word, not spoken only, but believed? For in the word itself, the passing sound is one thing, the abiding virtue another. This word of faith is of such avail in the Church of God, that by Him who believes, presents, blesses, sprinkles the infant, it cleanseth that infant, though itself is unable to believe.

"I am," He says, "the true vine, and my Father is the husbandman. Every branch in me that beareth not fruit, He taketh away; and every one that beareth fruit, He purgeth it, that it may bring forth more fruit." Are, then, the husbandman and the vine one? Christ is the vine in the same sense as when He said, "The Father is greater than I;" but in that sense wherein He said, "I and my Father are one," He is also the husbandman. And yet not such a one as those, whose whole service is confined to external labor; but such, that He also supplies the increase from within. "For neither is he that planteth anything, neither he that watereth; but God that giveth the increase." But Christ is certainly God, for the Word was God; and so He and the Father are one: and if the Word was made flesh, that which He was not before, He nevertheless still remains what He was. And still more, after saying of the Father, as of the husbandman, that He taketh away the fruitless branches, and pruneth the fruitful, that they may bring forth more fruit, He straightway points to Himself as also the purger of the branches, when He says, "Now ye are clean through the word which I have spoken unto you." Here, you see, He is also the pruner of the branches, a work which belongs to the husbandman, and not to the vine; and more than that, He maketh the branches His workmen. For although they give not the increase, they afford some help; but not of themselves: "For without me," He says, "ye can do nothing." And listen, also, to their own confession: "What, then, is Apollos, and what is Paul but ministers by whom ye believed, even as the Lord gave to every man. I have planted, Apollos watered." And this, too, "as the Lord gave to every man;" and so not of themselves. In that, however, which follows, "but God gave the increase," He works not by them, but by Himself; for work like that exceeds the lowly capacity of man, transcends the lofty powers of angels, and rests solely and entirely in the hands of the Triune Husbandman. "Now ye are clean," that is, clean, and yet still further to be cleansed. For, had they not been clean, they could not have borne fruit; and yet every one that beareth fruit is purged by the husbandman, that he may bring forth more fruit. He bears fruit because he is clean; and to bear more, he is cleansed still further. For who in this life is so clean as not to be in need of still further and further cleansing? seeing that, "if we say that we have no sin, we deceive ourselves, and the truth is not in us; but if we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness;" to cleanse in very deed the clean, that is, the fruitful, that they may be so much the more fruitful, as they have been made the cleaner.
