Origen

“ But we, the eyes of whose soul have been opened by the Word, and who see the difference between light and darkness, prefer by all means to take our stand “in the light,” and will have nothing to do with darkness at all. The true light, moreover, being endued with life, knows to whom his full splendours are to be manifested, and to whom his light ”

“ And if we must speak at all of “sight being affected and injured,” what other eyes shall we say are in this condition, than his who is involved in ignorance of God, and who is prevented by his passions from seeing the truth? Christians, however, by no means consider that they are blinded by the words of Celsus, or any other who is opposed to the worship of God. ”
