i put catholicism under vanilla-flavor satanism. there is a video presentation by a satanic priest who said that in order to become their priest, he first had to become a catholic priest. atheists cannot be admitted. i also know a lady bitcoiner who wrote a thesis while in her catholic church  school demonstrating the parallels between catholicism and satanism. 

It seems Catholicism is getting some traction in the past decade and should gain more adepts in the years to come.

Orthodox churches seem to be getting people too. their online peers are quite vocal but their irl presence is not that noticeable.
