I am the true vine, and my Father is the vine dresser.
All Commentaries on John 15:1 Go To John 15
Augustine of Hippo
AD 430
He says this as being the Head of the Church, of which weare 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 you are turned into the degenerate plant of a strange vine to me (Jer 11:21). For how is that a true vine, which when grapes are expected from it, produces only thorns? .
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 plowing: 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 plow, as it were, of His word, in sowing in us the seeds of His commandments, in waiting forthe fruits of piety.
And who is there in this world so clean, that he cannot be more and more changed? Here, if we say that we have nosin, we deceive ourselves. He cleans 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 said, My Father is greater than I; but in that He said, I and My Father are one, He is the husbandman; not like those who carryon an external ministry only; for He gives increase within. Thus He calls Himself immediately the cleanser of the branches: Now you are clean through the word, which I have spoken to you. He performs the part of the husbandman then, as well as of the vine. But why does He not say, you are clean by reason of the baptism wherewith you are washed? Because it is the word in the water which cleans. Take away the word, and what is the water, which but water. Add the word to the element, and you have a sacrament. Whence has the water such virtue as that by touching the body, it cleans 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 cleanses that infant, though itself is unable to believe.
