Augustine of Hippo
Catena Aurea · Johannesevangelium 14
Philip saith unto him, Lord, shew us the Father, and it sufficeth us. Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father? Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works. Believe me that I am in the Father, and the Father in me: or else believe me for the very works’ sake.
(Tr. lxx. 3. and lxxi. 1) He then addresses all of them, not Philip only: The word that I speak unto you, I speak not of Myself. What is, I speak not of Myself, but, I that speak am not of Myself? He attributes what He does to Him, from whom He Himself, the doer, is.
