“Catholics worship idols and pray to dead people.”
I guess they don’t know that necromancy is strictly forbidden in the Bible (Deuteronomy). It’s clear that anyone who consults with the dead is detestable to God. Saul’s death was punishment for having a medium try to contact Samuel. (Of course, since it’s in the Bible they ignore it. They elevate the teachings of pedophiles and charlatans over the Bible.)
And they have so many idols! I had to play organ for a funeral in a Catholic Church once. Super creepy.
