A couple of friends lately have brought up the subject of prayer and worship with me, and I rather like one of the answers I've typed out, so I'll share parts of it.
First, context. I was raised casually-Christian. In that I understood I was a Christian, I went to church a handful of times a year with various family members, but I didn't really have any active worshipping or churching happening in my life. I also occasionally went to synagogue or temple with various friends or classmates. I went to school with a lot of Jewish friends, so 7th and 8th grade meant a lot of Bar and Bat Mitzvahs (is there a collective term for that?). I went to a Baptist summer camp, and was baptized at least a couple of times (I'm pretty sure I was baptized as a baby, too?).
As I got older, I learned more about other religions, both real-world and fictional. I took a couple of cultural anthropology courses, which were enthralling for examining religions from without. Sci-fi and fantasy fiction world-building have to include religion as part of those worlds, and often include a lot of thought and discussion about how a particular religious view can influence entire moral structures and behavior mores. If you ask me now about my guiding faith, I'll point you toward IDIC (https://meronym-thoughts.blogspot.com/p/idic-infinite-diversity-in-infinite.html). Yep, that's from Star Trek.
