Evangelion is a disgusting anime to consider part of your national personification. Drop it and pick up Ghibli films more please Japan.
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.
The "weird mysticism" is just the reification (pun intended) of the urge to self-harm. i.e. Literally turning into a puddle of emotion, or allowing oneself to be crucified.
It's visceral in a way I've never seen before or since. Going all in on a surface-level understanding paid off in my mind.
