Augustine of Hippo
Catena Aurea · Johannesevangelium 8
Then said they unto him, Where is thy Father? Jesus answered, Ye neither know me, nor my Father: if ye had known me, ye should have known my Father also. These words spake Jesus in the treasury, as he taught in the temple: and no man laid hands on him; for his hour was not yet come.
(Tract. xxxvii. 2.) As if He said, Ye ask where is Thy Father? As if ye knew Me already, and I were nothing else but what ye see. But ye know Me not, and therefore I tell you nothing of My Father. Ye think Me indeed a mere man, and therefore among men look for My Father. But, forasmuch as I am different altogether, according to My seen and unseen natures, and speak of My Father in the hidden sense according to My hidden nature; it is plain that ye must first know Me, and then ye will know My Father; If ye had known Me, ye would have known My Father also.
