It could be said, if your faith is weak, to avoid any number of books from Vermes, to Harry Potter. If you are well catechized and firm in your faith, and you want to read it, go ahead…If staying away from books that question conventional Christian or even Catholic teachings was a requirement, we would have been cheated out of some great Church theologians, because theology requires an examination of many different viewpoints…Augustine and Aquinas would never have been able to publish some great theological books and treatises if they could not read opposing thought.
