Hilary of Poitiers — as excerpted in the Catena Aurea on John 5:19-20

“(vii. de Tr. c. 17) That the wholesome order of our confession, i. e. that we believe in the Father and the Son, might remain, He shews the nature of His birth; viz. that He derived the power of acting not from an accession of strength supplied for each work, but by His own knowledge in the first instance. And this knowledge He derived not from any particular visible precedents, as if what the Father had done, the Son could do afterwards; but that the Son being born of the Father, and consequently conscious of the Father’s virtue and nature within Him, could do nothing but what He saw the Father do: as he here testifies; God does not see by bodily organs, but by the virtue of His nature.”
