Ask @bradyhardin:

Hey! I have known for a while that the historical Jesus didn't exist. Yet, I find myself still valuing scriptures as sacred texts because of their original text/context being rooted in other sacred works. Am I delusional to still read scriptures from an esoteric point of view?

Delusional? Hell no.
My biggest influence for understanding this is Joseph Campbell, who wrote on the Hero's Journey. He showed how religious have many values in common and what that says about humanity. I'm all for viewing from wide points of view, and it sounds like that's what you're doing!
