I "found" this (it wasn't really lost) posted to a covenmate's Facebook page. A sermon on Paganism by a Catholic priest who actually knows what he's talking about, and who speaks plainly and clearly on the subject without getting all emotional about it.
Set aside about twenty-five minutes -- with your lunch, maybe -- and watch and listen. Learn from a Christian if you won't learn from a Pagan.
