Catena Aurea on John 15:12–16: Augustine of Hippo

But how did He make known to His disciples all things that He had heard from the Father, when He forebore saying many things, because He knew they as yet could not bear them? He made all things known to His disciples, i. e. He knew that He should make them known to them in that fulness of which the Apostle saith, Then we shall know, even as we are known. (1 Cor. 13:12) For as we look for the death of the flesh, and the salvation of the soul; so should we look for that knowledge of all things, which the Only-Begotten heard from the Father.
