These things I have written to you concerning those who would lead you astray.

 It has to be noted that an intellectual approach to religion is not necessarily ethical at all. If religion is a series of mental problems, if God is the goal at the end of intense mental activity, religion becomes something not very unlike the higher mathematics. It becomes intellectual satisfaction and not moral action; and the plain fact is that many of the great Greek thinkers were not specially good men. Even men so great as Plato and Socrates saw no sin in homosexuality. A man could know God in the intellectual sense but that need not make him a good man.
