Origen

“ He then addresses to us these words: “If, instead of exercising your senses, you look upwards with the soul; if, turning away the eye of the body, you open the eye of the mind, thus and thus only you will be able to see God.” ”

“ This twofold kind of vision in us was familiar to our Saviour, who says, “For judgment I am come into this world, that they which see not, might see, and that they which see might be made blind,” [5] —meaning, by the eyes that see not, the eyes of the mind, which are enlightened by His teaching; and the eyes which see are the eyes of sense, which His words do render blind, in order that the soul may look without distraction upon proper objects. All true Christians therefore have the eye of the mind sharpened, and the eye of sense closed ”

“ We have then to consider what the philosopher wishes us to hear from him. But instead of instructing us as he ought, he abuses us; and while he should have shown his goodwill to those whom he addresses at the outset of his discourse, he stigmatizes as “a cowardly race” men who would rather die than abjure Christianity even by a word, and who are ready to suffer every form of torture, or any kind of death. ”
