It's interesting to read everyone's experiences. I'll keep this brief even though I can tend to be long-winded.
Raised in a loose Protestant Christian family. Began questioning my religion and God when I was a young teen. I think my first encounter with Buddhism was through reading Kerouac. A girlfriend later bought Steve Hagen's introduction to Buddhism for me which I poured over several times. Also invested in Goddard's Bible and subsequently became stumped by the deep philosophy of the Surangama Sutra. Went off to college to study English and Asian Religions. Became friends with a professor who taught Buddhism - specfically Tibetan Buddhism. Around this time, my practice failed. I got too caught up in college life to make time for anything moral. Drifted into an on-again-off-again atheism/agnosticism. Sometimes I tried returning to Christianity. Began studying early Christianity in an attempt to refute it. Eventually discovered that I needed something to feel the void I was starting to notice inside of me, so I tried incorporating God into my life through various means and religions. Once I began to realize the truth of aging and death, I converted to Catholicism. My faith in it waxed and waned, though I was a better Catholic than I had been at anything else. My Catholicism was largely a social tool, though. While a Catholic, I got interested in things like Centering Prayer (which is essentially meditation) and the works of Thomas Merton which greatly reflected a Zen mindset. I never really forgot my early reading, and Buddhism had largely formed the backbone of my existentialist philosophy even if I failed to practice it. Over time, with more reading, I lost my faith in the Church, in the dogmas, and the Creed. I then considered God. God angered me because of his inconsistencies. Of course, while I now have not entirely ruled out the idea of a Supreme Being, I am positive nothing can be known about it, especially not through private or public revelation. I am also positive this Supreme Being lies at the center of the matrix of impermanence. I suppose I imagine a Trimurti-esque Being more than a Loving Father. In essence, I've left God behind in search of a different salvation, recognizing that the Supreme Being heeds no prayers, recognizes no victims, regards no accidents. I've returned the Dharma because it remains fundamentally true through winter, summer, heaven, hell, light and darkness.
