“And this is one of the most crucial definitions for the whole of Christianity; that the opposite of sin is not virtue but faith.”

“The paradox in Christian truth is invariably due to the fact that it is the truth that exists for God. The standard of measure and the end is superhuman; and there is only one relationship possible: faith.”

“If anyone thinks he has faith and yet is indifferent towards this possession, is neither cold nor hot, he can be certain that he does not have faith. If anyone thinks he is Christian and yet is indifferent towards his being a Christian, then he really is not one at all. What would we think of a man who affirmed that he was in love and also that it was a matter of indifference to him?”

“My melancholy is the most faithful sweetheart I have had.”

“There is something frightful in the fact that the most dangerous thing of all, playing at Christianity, is never included in the list of heresies and schisms.”

“to have faith is precisely to lose one's mind so as to win God.”

“In the deepest sense, the being in a state of sin is the sin, the particular sins are not the continuation of sin, they are expressions of its continuation.”
