Origen

“ But since it is the work of God alone, in conformity with His own Spirit, and along with that of Christ, to take up His abode invisibly in those persons whom He judges worthy of being visited; so, on the other hand, is our object to try, by means of arguments and treatises, to confirm men in their faith, and to earn the name of “workmen needing not to be ashamed, rightly dividing the word of truth.” ”

“ And there is one thing above all which it appears to us we ought to do, if we would discharge faithfully the task enjoined upon us by you, and that is to overturn to the best of our ability the confident assertions of Celsus. ”
