My wife is Catholic. I'm not, but I attend mass with her. Her parish priest has quoted C.S. Lewis at least once that I can remember, and I think more than once.I'm curious as to what catholics and the orthodox think of CS Lewis. For english speaking protestants he's like a our own Thomas Aquinas. Is he has popular in other denominations?
I've only read the Narnia series as a kid and The Screwtape Letters as an adult. I think it was in the introduction to the latter that he says that the two most common mistakes regarding demons are 1) not believing in them and 2) believing in them and
taking an unhealthy interest in them. That always stuck with me and has helped me avoid making either mistake myself.
