I was never raised into a religion. My family was supposedly christian but they really dont care. Nobody in my family went to church, we just said we were christians.
This was more or less my situation. We were technically Presbyterian though I think my parents were highly uncomfortable with the idea of predestination. When I was young, we went to church every Christmas and Easter, then eventually only on Christmas, and finally not at all, partially due to the objections of my brother and I (and later my sister), who all decried church as boring.
I remember overhearing a conversation between my parents at the time that they were worried, not that we were faithless, but that we weren't growing up the same they did. My mother was particularly worried about this. There was no apparent attempts thereafter to make our family more religious, however, so I can only assume that my parents decided that growing up the same way they did was not important.
Shortly after my brother and I turned 15, however, my parents suddenly found renewed interest in religion, but this time not in Presbyterianism. They brought us (more like dragged, almost literally in my brother's case) to a meeting of the local chapter of the Unitarian Universalist Association. While I had come to associate church with lengthy, boring sermons accompanied by excessive pomp and ceremony, I enjoyed congregation for the first time. I also found UU far more in tune with my own beliefs than I had come to see Christianity; while Christianity has many great core concepts, they are too often ignored and obscured, and UU does not demand prostration before a god. My entire family converted and thereafter attended congregation semi-regularly, as was typical among our fellow UUs. (Meetings are generally on Sunday but sometimes fall on Saturday, and no one attends every meeting.)
My extended family has extremely varied religious beliefs. On my mother's side, my uncle is part of the Missouri Synod of the Lutheran church. (Those are the crazy Lutherans; he's a religious fanatic.) My eldest aunt is Catholic, my second-eldest aunt is Baptist, and my youngest aunt is atheist. My mother is UU. All five were raised Presbyterian, so you can see that predestination is not popular in the modern world. On my father's side, my elder aunt was Presbyterian, my younger aunt was Quaker, and my uncle is Buddhist. My father is UU; all but his eldest sister converted away from Presbyterianism as well.
