My atypical example:
My parents weren't religious. My father was irreligious in general. My mother was and remains, minimally religious. My mother, not my father, took me to church a very few times, as a child. It introduced me to the concept of religion (beyond what I gleaned from the general culture and Biblical themed movies). We never read the Bible at home, though we had several. I only read two books of the Bible as a child, Genesis and Revelations, especially Genesis. I had communion in church one time as child, but that time I experienced a numinous feeling afterward (something Carl Jung sought, but didn't receive). As a teen I had a general curiosity about religion, not limited to Christianity, but covering many religions. Also as a teen, I had been brought into the Gnostic religion called Freemasonry by my grandparents. So as I entered adulthood, I only had a limited experience with religion, and it was mostly self-directed, out of curiosity. I had never been made to do anything, but I had been introduced to it by adults, who lived examples of adult behavior. Subsequent influence started when I got married ... as an adult, and under the stimulus but not compulsion of my wife, my self-direction increased exponentially, and continues post-divorce into senior-hood.
Christianity remains of interest, but I see myself as marginally Jewish, and am interested in all religions, as part of my general interest in all anthropology and psychology.
