I grew up in a mostly non-practicing Catholic family. I've been to church maybe 10 times in my 37 years of existence, and hated it every single time. My mom and older brother definitely believe, with the brother being a semi-regular at his church. My oldest brother believes in something, but it's a loose, generalized spirituality.
