Catena Aurea on John 14:12–14: Augustine of Hippo

And that no one might attribute the merit to himself, He shews, that even those greater works were His own doing: And whatsoever ye shall ask in My name, that will I do. Before it was, He shall do, now, I will do: as if He said, Let not this appear impossible to you. He that believeth in Me, will not be greater than I; but I shall do greater works then than now; greater by him that believeth on Me, than now by Myself; which will not be a failing, but a condescension.
