Article is from when the first season aired:https://www.polygon.com/tv/2017/7/29/16062578/netflix-castlevania-religion-corruption-warren-ellis>The leader of the demon army enters the cathedral and devours the Bishop at the altar, but not before forcing the Bishop to confront his own hypocrisy and recognize that he is an arrogant, ignorant and ungodly human being. Castlevania’s message is not ambiguous: Organized religion is an instrument of evil that leads straight to Armageddon.
I don't get what shitlibs mean by "organized religion", even though I see it all the time. Christianity's dogma itself demands that it be organized - there can be no "unorganized" Christianity. I think they mean "you can follow Christianity but don't ever act on it, or enact will to power by giving Christianity state authority", basically just "let us get away with all our polices, and never enact the polices you want".
Also the slut deserved to be burned at the stake for cavorting with demons.
