Seest thou that the Son contributeth not less than the Father towards the care of the disciples? The Father purgeth, but He keepeth them in Himself. The abiding in the root is that which maketh the branches to be fruit-bearing. For that which is not purged, if it remain on the root, bears fruit, though perhaps not so much as it ought; but that which remains not, bears none at all. But still the “purging” also hath been shown to belong to the Son, and the “abiding in the root,” to the Father, who also begat the Root. Seest thou how all is common, both the “purging,” and the enjoying the virtue which is from the root?
