Catena Aurea on John 8:19–20: Augustine of Hippo

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.
