Hilary of Poitiers
Catena Aurea · Johannesevangelium 5
Then answered Jesus and said unto them, Verily, verily, I say unto you, The Son can do nothing of himself, but what he seeth the Father do: for what things soever he doeth, these also doeth the Son likewise. For the Father loveth the Son, and sheweth him all things that himself doeth: and he will shew him greater works than these, that ye may marvel.
(vii. de Trin. c. 19) Nor did the heavenly discourse lack the caution, to guard against our inferring from these words any difference in the nature of the Son and the Father. For He says that the works of the Father were shewn to Him, not that strength was supplied Him for the doing of them, in order to teach that this shewing is substantially nothing else than His birth; for that simultaneously with the Son Himself is born the Son’s knowledge of the works the Father will do through Him.
