I was baptized in the Catholic Church when I was one month old. However, my father was a decidedly lapsed Catholic and my mother is a non-churchgoing Methodist. I didn't go to church till I was ten years old. A classmate of mine, whose father was a Church of Christ pastor, invited me to her house, gave me a King James Bible, and invited me to attend her church. When I told Mom about it, she told me, "you were baptized Catholic. If you want to go to church, go to the Catholic Church." I didn't know I had been baptized Catholic until then. But Mom dropped me off at the local Catholic parish just before the 10:45 am Sunday Mass, and went shopping for groceries while I was attending Mass. I was enchanted (this was in the late 1970s in a typical large suburban parish in the Archdiocese of Los Angeles) and insisted on going to CCD classes so I could have my First Holy Communion. After I received my First Holy Communion, my church attendance became sporadic: nobody had told me that deliberately missing Sunday Mass without a good reason is a mortal sin. I was confirmed during my freshman year in college (1985) because I wanted to be confirmed. Again, catechesis was not the greatest.
In 1990, I began attending an Orthodox mission parish and entered the Orthodox Church that year by chrismation. Alas, the jurisdiction was run by a bishop of dubious status who was credibly accused of molesting kids. I switched over to the Serbian Diocese of Western America a few years later, and spent ten years (1993-2003) there. However, lacking Serbian ancestry or a husband of Serbian descent, I didn't feel completely at home among the Serbian-Americans I knew. I was also interested in forms of consecrated life besides rural monasticism. So I reverted to Catholicism, became a Lay Carmelite, and that is where I am today.
As for how this has affected me... I believe fervently in the afterlife, and am a hopeful universalist (I hope everyone ultimately ends up in Heaven). I doubt free will, and have trouble believing God is always good. I am Catholic because Christianity is in the historical background of Western society, and because I feel I must have an organized religion to tether my spirituality. Does this answer the question sufficiently? Thank you.
