Augustine of Hippo

His manhood was much more plainly and readily recognized by strangers, who, indeed, were not wrong in believing him to be man, but they did not understand his being God as well as man. Hence Jeremiah says, "He is man, and who shall know him?" He is a man, for it is made manifest that he is a brother. And who shall know him? For it is concealed that he is a husband [to the church]. This must suffice as a defense of our father Abraham against Faustus's imprudence and ignorance and malice.
