Music is music. If we could only hear or read those things that are created by Catholics, we would miss a lot of things that are good. If I gave you a remarkable, 2000 year old Indian arrowhead, you wouldn’t refuse it just because the Indian artificer was a pagan. Now, if I was digging up arrowheads as part of a program to promote paganism, you might not want to pay me for it. But if I gave it to you, you’re not supporting paganism, any more than you’re supporting Mormonism if you accept a CD as a gift.
Anyway, that’s how I see it.
