I also read the letter to a CES director and was had my faith challenged. Prior to that I was blown away when I read about Brigham young and the violence in the early Utah church. I think that you can come out of these experiences with your faith intact but it will probably be changed. You will probably have to find a new way to believe. I certainly did. I am much less of a literal believer and more independent and thoughtful. I admit that I grieve over the innocent and undoubting faith I used to have. But here I am with what I think is probably a more mature faith and still an active member who gets all of the benefits of full participation in the church even though I see that Mormonism rests on a broken history. I have come to celebrate our brokenness because that can be holy too. We’re all just trying to find god in this messy world. Mormonism is still the path I chose to do so.
