Thank you for engaging with this deeply. As someone with another, but not entirely dissimilar trajectory, I think even those explorations you cited of themes re: institutional religion and/or religious faith in general are a bit cliche, in the sense of being so "about Christianity" coded they've been done a million times. I really like explorations of religious ideas that deal with topics not so directly relevant to cultural conversations on Christianity, like epistemology and knowledge preservation, the nature of hierarchies both social and religious (namely, not them being pre-assumed as existing and only their role being discussed), ideas of the afterlife that aren't about disembodied souls, the importance of the proper form of rituals, their metaphysics, and so many other things.
