What changed your mind, if you don't mind my asking?
A combination of a few things. One, being a big fan of history, and eventually you get to a point reading history if you have empathy for the people you're reading about that a lot of times they're smart rational people working in the frameworks they have, and just because they don't heckin love science that doesn't make them dumb. A lot of history is humanity being very irrational as well, but I digress. Secondly it would be my natural inclination towards things that cannot be explained by science or the material world. I've always liked the quote from Hamlet "There are more things on Heaven and Earth, than are dreamt of in your philosophies, Horatio". As a kid I grew up listening to things like Coast To Coast AM, and that gave me an inclination to the supernatural, and a fascination with all things occult and esoteric. I would spend nights reading the fringiest of fringe shit on Hermetics, Theosophy, Rosicrucianism etc. without even considering picking up the Bible. Not out of a sense of pride or anything like that but just lack of interest. Third because I have a bad habit because of my upbringing of constantly being self-critical and what I like to call "self auditing" my own beliefs. When I got into meditation in my early 20s I discovered that I could take my brain out of my head in a metaphorical sense and examine how I thought about things looking for inconsistencies and things I believed purely out of emotion. This partly also comes from being raised/being a low self-esteem kid growing up but I've PL'd enough as it is.
So because of all those things, it lead to gain an interest in the Bible critically once I learned what was in it. The historicity of various books, letters, and how they each have a story and the richness of the stories because they're all 2000-years-old+ means you can get really deep into something like Mark, even though it's the shortest of the Gospels. Looking at the Bible critically and the teachings of Jesus eventually lead me to finding it the most rational and simultaneously emotionally satisfying life philosophy. I've always believed that true evil exists in the world too. But the good news is, that means true good has to exist as well, and that true good comes from somewhere. You can probably imagine my bad habit of constantly "self auditing" can lead to being agnostic on pretty much everything. So Christ's teachings give me a foundation of principals to rely on that were already there, I just didn't know how to describe them intellectually.
So that leads me to where I am now, which I like to autistically call nondenominational Christian mysticism. I've enjoyed learning about all the different aspects of the Church, from Protestantism which I'm more familiar with, Catholicism and Orthodoxy. and I think there's wisdom in all of them.
