I am the true vine. Christ, says St. Augustine, speaks of himself, as man, when he compares himself to a vine, his disciples to the branches, and his Father to the husbandman. He himself, as God, is also the husbandman. — Without me, you can do nothing, that shall be meritorious of a reward in heaven. (Witham) — These words are supposed to have been spoken by our Saviour, when on the road, as he was going from the house, where he had supped, to the garden of Olives. It was then about midnight. (Calmet) — Though many other interpreters think they were spoken before Jesus Christ left the house.
It is generally agreed that Christ's discourse in this and the next chapter was at the close of the last supper, the night in which he was betrayed, and it is a continued discourse, not interrupted as that in the foregoing chapter was; and what he chooses to discourse of is very pertinent to the present sad occasion of a farewell sermon. Now that he was about to leave them, I. They would be tempted to leave him, and return to Moses again; and therefore he tells them how necessary it was that they should by faith adhere to him and abide in him. II. They would be tempted to grow strange one to another; and therefore he presses it upon them to love one another, and to keep up that communion when he was gone which had hitherto been their comfort. III. They would be tempted to shrink from their apostleship when they met with hardships; and therefore he prepared them to bear the shock of the world's ill will. There are four words to which his discourse in this chapter may be reduced; 1. Fruit, ver 1-8. 2. Love, ver 9-17. 3. Hatred, ver 18-25. 4. The Comforter, ver 26, 27.
Verses 1-8 Jesus Christ is the Vine, the true Vine. The union of the human and Divine natures, and the fulness of the Spirit that is in him, resemble the root of the vine made fruitful by the moisture from a rich soil. Believers are branches of this Vine. The root is unseen, and our life is hid with Christ; the root bears the tree, diffuses sap to it, and in Christ are all supports and supplies. The branches of the vine are many, yet, meeting in the root, are all but one vine; thus all true Christians, though in place and opinion distant from each other, meet in Christ. Believers, like the branches of the vine, are weak, and unable to stand but as they are borne up. The Father is the Husbandman. Never was any husbandman so wise, so watchful, about his vineyard, as God is about his church, which therefore must prosper. We must be fruitful. From a vine we look for grapes, and from a Christian we look for a Christian temper, disposition, and life. We must honour God, and do good; this is bearing fruit. The unfruitful are taken away. And even fruitful branches need pruning; for the best have notions, passions, and humours, that require to be taken away, which Christ has promised to forward the sanctification of believers, they will be thankful, for them. The word of Christ is spoken to all believers; and there is a cleansing virtue in that word, as it works grace, and works out corruption. And the more fruit we bring forth, the more we abound in what is good, the more our Lord is glorified. In order to fruitfulness, we must abide in Christ, must have union with him by faith. It is the great concern of all Christ's disciples, constantly to keep up dependence upon Christ, and communion with him. True Christians find by experience, that any interruption in the exercise of their faith, causes holy affections to decline, their corruptions to revive, and their comforts to droop. Those who abide not in Christ, though they may flourish for awhile in outward profession, yet come to nothing. The fire is the fittest place for withered branches; they are good for nothing else. Let us seek to live more simply on the fulness of Christ, and to grow more fruitful in every good word and work, so may our joy in Him and in his salvation be full.
We are of nature dry and fit for nothing but the fire: Therefore that we may live and be fruitful, we must first be grafted into Christ, as it were into a vine by the Father’s hand: and then be daily shred with a continual meditation of the word and the cross; otherwise it shall not avail any man at all to have been grafted, unless he cleave fast unto the vine, and so draw juice out of it.
He here shews, that the virtuous themselves stand in need of the help of the husbandman; therefore the Almighty sends them tribulations, and temptations, that they may be cleansed, and rendered firm, like the vine, which, the more it is pruned, the more vigorous are its shoots. (St. Chrysostom, hom. lxxv. in Joan.)
(1.) The doom of the unfruitful (v. 2): They are taken away. [1.] It is here intimated that there are many who pass for branches in Christ who yet do not bear fruit. Were they really united to Christ by faith, they would bear fruit; but being only tied to him by the thread of an outward profession, though they seem to be branches, they will soon be seen to be dry ones. Unfruitful professors are unfaithful professors; professors, and no more. It might be read, Every branch that beareth not fruit in me, and it comes much to one; for those that do not bear fruit in Christ, and in his Spirit and grace, are as if they bore no fruit at all, Hos 10 1. [2.] It is here threatened that they shall be taken away, in justice to them and in kindness to the rest of the branches. From him that has not real union with Christ, and fruit produced thereby, shall be taken away even that which he seemed to have, Luke 8 18. Some think this refers primarily to Judas.
(3.) The benefits which believers have by the doctrine of Christ, the power of which they should labour to exemplify in a fruitful conversation: Now you are clean, v. 3. [1.] Their society was clean, now that Judas was expelled by that word of Christ, What thou doest, do quickly; and till they were got clear of him they were not all clean. The word of Christ is a distinguishing word, and separates between the precious and the vile; it will purify the church of the first-born in the great dividing day. [2.] They were each of them clean, that is, sanctified, by the truth of Christ (ch. 17 17); that faith by which they received the word of Christ purified their hearts, Acts 15 9. The Spirit of grace by the word refined them from the dross of the world and the flesh, and purged out of them the leaven of the scribes and Pharisees, from which, when they saw their inveterate rage and enmity against their Master, they were now pretty well cleansed. Apply it to all believers. The word of Christ is spoken to them; there is a cleansing virtue in that word, as it works grace, and works out corruption. It cleanses as fire cleanses the gold from its dross, and as physic cleanses the body from its disease. We then evidence that we are cleansed by the word when we bring forth fruit unto holiness. Perhaps here is an allusion to the law concerning vineyards in Canaan; the fruit of them was as unclean, and uncircumcised, the first three years after it was planted, and the fourth year it was to be holiness of praise unto the Lord; and then it was clean, Lev 19 23, 24. The disciples had now been three years under Christ's instruction; and now you are clean.
