Origen

“ Nay, if the Jew perceive the meaning of the prophetic Scriptures, he will be able to show that it is for no light reason that God employs threatenings and revilings, when He says, “Woe unto you,” and “I tell you beforehand.” And how should God employ such expressions for the conversion of men, which Celsus thinks that even a prudent man would not have recourse to? But Christians, who know only one God—the same who spoke in the prophets and in the Lord (Jesus) —can prove the reasonableness of those threatenings and revilings, as Celsus considers and entitles them. ”

“ And is it not a ridiculous assertion regarding Jesus, to say that He was unable to persuade men, when you compare the state of matters not only among the Jews, who have many such instances recorded in the prophecies, but also among the Greeks, among whom all of those who have attained great reputation for their wisdom have been unable to persuade those who conspired against them, or to induce their judges or accusers to cease from evil, and to endeavour to attain to virtue by the way of philosophy? ”

“ Unless, indeed, you would have God, or one who partakes of the divine nature, when conversing with men, to have regard to His own nature alone, and to what is worthy of Himself, but to have no regard to what is fitting to be brought before men who are under the dispensation and leading of His word, and with each one of whom He is to converse agreeably to his individual character. ”
