Augustine of Hippo — as excerpted in the Catena Aurea on John 12:44-50

“(i. de Trin. c. xii. [26.]) I judge him not; the word that I have spoken shall judge him: for I have not spoken of Myself. The word which the Son speaks judges, because the Son did not speak of Himself: for I have nut spoken of Myself: i. e. I was not born of Myself.”
