30 Wherefore that heretic, (inasmuch as our discourse is of those who wish to be called Christians,) I ask you, what reason he alleges to me? What is there whereby for him to call me back from believing, as if from rashness? If he bid me believe nothing; I believe not that this very true religion has any existence in human affairs; and what I believe not to exist, I seek not. But He, as I suppose, will show it to me seeking it: for so it it written, “He that seeks shall find.” Therefore I should not come unto him, who forbids me to believe, unless I believed something. Is there any greater madness, than that I should displease him by faith alone, which is founded on no knowledge, which faith alone led me to him?
