"There is a sense in which it is true to say that you can prove anything you like from the Bible. That is how heresies have arisen. The heretics were never dishonest men; they were mistaken men. They should not be thought as men who were deliberately setting out to go wrong and to teach something that is wrong; they have been some of the most sincere men that the Church has ever known. What was the matter with them?
Their trouble was this; they evolved a theory and they were rather pleased with it; then they went back with this theory to the Bible and they seemed to find it everywhere".
