So Christian Science is obviously a weird cultish religion that lets kids die but growing up as one it ruined multiple things about both Catholicism and Protestantism for me because the core theology actually sort of makes sense in a way that those kinda do not, and one of those ways was finding the fact that Catholics claim to be monotheistic but pray to saints extremely fucking odd. I remember when my friend became a hardcore Catholic convert we argued about it a few times lol.
