Short Answer: Non-spiritual INFJ but open to being convinced otherwise at this moment in time.
Long Answer: See below
I started out as Ukrainian Orthodox. After my parents divorced, my religious upbringing was that of whomever my mother was dating. I have tried Christian Science, Catholicism, Baptism, Methodist, and a few others. At my dad's house his wife was Lutheran. So whenever I lived there, which was sporadic, I was Lutheran. My dad always went with her to church but I don't think I believe that he ever really invested in spirituality or faith.
As I went off to college I learned about Buddhism, Hinduism, Taoism, Wicca, Islam, and other religions. I am a fan of learning. I think at that point I became agnostic.
After that I became more rooted in science. I am starting to reexamine though, I did really like the philosophies of Buddhism. I currently live in Arizona and in my area there are a lot of Mormons which is interesting, but not for me. So I am just very open to ideas but rooted in a belief that a formal organized religion is not necessarily for me.
I had an almost identical experience with religion- in as far as my parents were Episcopalian, but when they split my dad was an atheist, my mom got into Foursquare, as a child I went to extreme Baptist Bible camps, my dad got into Nazarene. So at my mom's church we danced and sang long songs and talked in tongues. At my grandparents Bible Camp I was scared to hell, and at my dad's church everyone was super super conservative.
For the most part now, I am much more into spirituality. I think what I fundamentally don't like about religion is how double-sided it is. By sheltering people from the world, they create a naivety that upon entering the real world leaves people defenseless and very vulnerable. By pretending to be holier than thou, insecurities are fostered, and I don't know why I have this horribly sneaking suspicion, but I don't think people are "born" bad. I think that religion is one of the biggest evils of the world, because religion tends to always hold back people from being as great as they could truly be. If I lived with the label of "sinner" my whole life, I think I would be carrying a huge burden.
I was a very devout Christian as a child, and tried very hard to convert some of my friends, and listened to Christian radio before school. A few experiences turned me off- particularly my experience at Bible Camp- the first year it was about working on your relationship on God, and the next year it was all about Hell, and each cabin was supposed to be "born again" but I just didn't feel it. Then I became an atheist, but my parents still forced me to go to Church, and then I just hated it more and more.
Now, I am "spiritual" in the sense that I hate religion, love science, but also believe that we have a soul and do reincarnate. I am a huge fan of gnosticism, Philip K. Dick and Jung, as well as some aspects of Discordianism and Robert Anton Wilson. I believe that there is hidden wisdom, and am typically skeptical of en-masse anything. I like the idea that we are on Earth to grow and improve ourselves, and any dogma that wants us to stay ignorant or believe in faith is total bull.
