I've got a brother and sister that do missionary work and my family has long been involved in the church. I broke away when I started noticing how the people used the Bible to control others. Took a long hard look at it, and said, Nope. Now when my sister and I get in a discussion, she'll start with, "in the bible it says...." and I cut her off reminding her that I don't believe the Bible is the word of God. It took a while, but I got through to her that it was a bad tactic. I'd counter with Aesop's Fables, Greek mythology, Grimm's Fairy Tales, and so forth.
