Tertullian

“ Never will I call the emperor God, and that either because it is not in me to be guilty of falsehood; or that I dare not turn him into ridicule; or that not even himself will desire to have that high name applied to him. If he is but a man, it is his interest as man to give God His higher place. Let him think it enough to bear the name of emperor. That, too, is a great name of God’s giving. To call him God, is to rob him of his title. If he is not a man, emperor he cannot be. Even when, amid the honours of a triumph, he sits on that lofty chariot, he is reminded that he is only human. ”

“ A voice at his back keeps whispering in his ear, “Look behind thee; remember thou art but a man.” And it only adds to his exultation, that he shines with a glory so surpassing as to require an admonitory reference to his condition. ”
