“I am the true vine, and my Father is the vinedresser.

John Calvin Reformed @genevareformer

1. I am the true Vine. The general meaning of this comparison is, that we are, by nature, barren and dry, except in so far as we have been engrafted into Christ, and draw from him a power which is new, and which does not proceed from ourselves.

Matthew Henry Presbyterian @wholebiblehenry

Here Christ discourses concerning the fruit, the fruits of the Spirit, which his disciples were to bring forth, under the similitude of a vine. Observe here, I. The doctrine of this similitude; what notion we ought to have of it. 1. That Jesus Christ is the vine, the true vine.

Commenting on John 15:1-8

Albert Barnes Presbyterian @notesbybarnes

Verse 1. I am the true vine. Some have supposed that this discourse was delivered in the room where the Lord's Supper was instituted, and that, as they had made use of wine, Jesus took occasion from that to say that he was the true vine, and to intimate that his blood was the real wine that was to give strength to the soul.
