From the age of 9 until the age of 24, I was deeply involved in a very sectarian Christian church--so much so that they supported me and sent me off in 1998 for a 2 year missionary trip with a huge worldwide Christian missions organization called Operation Mobilization.
I geographically returned to that church in early 2001, having married, and having changed enormously in a lot of ways.
A couple months later, my super awesome wife and I left that church--discontinued all association with it. We did not do so super gracefully.
Here's what I have to say about that: There is no scenario better than the one that happened. I'm *stoked* that we left--one of the best decisions in my whole life. I most certainly would not and could not be doing the amazing delightful work I'm doing now if I were still involved with that church. And we left in the best way we possibly could, as the people we were at that time and place.
