Origen

“ That we are not refuted, however, on the subject of our great Saviour, although the accuser may appear to refute us, will be manifest to those who peruse in a spirit of truth-loving investigation all that is predicted and recorded of Him. And, in the next place, since he considers that he makes a concession in saying of the Saviour, “Let him appear to be really an angel,” we reply that we do not accept of such a concession from Celsus; but we look to the work of Him who came to visit the whole human race in His word and teaching, as each one of His adherents was capable of receiving Him. ”

“ And he thinks he can meet either of these dilemmas at great length, although there is not a single real Christian who asserts that Christ was the only being that visited the human race. For, as Celsus says, “If they should say the only one,” there are others who appeared to different individuals. ”
