Evangelion is not “Japan’s version” of anything in terms of western religions. It’s one guy who was making a TV show. It’s not Japan’s “national personification.”
If you want to go down the rabbit hole you’ll find a lot of quotes from Anno and others on it.
A lot of it boils down to “we did this because it’s cool and we have no idea what Christianity is” down to Anno going “Yeah I could do this because no one in Japan is really going to care and I don’t really care about the Western world anyway.”

It’s fine to not like it but it’s quite a step to go “this is how Japan thinks.” It’s akin to saying America is personified by the Simpsons every time they go to Japan.
