Origen Against Celsus Book I

But since Celsus has declared it to be a saying of many Christians, that "the wisdom of this life is a bad thing, but that foolishness is good," we have to answer that he slanders the Gospel, not giving the words as they actually occur in the writings of Paul, where they run as follow: "If any one among you seemeth to be wise in this world, let him become a fool, that he may become wise. For the wisdom of this world is foolishness with God."[32]
