For the Bible Tells Me So

From the web site:

Through the experiences of five very normal, very Christian, very American families -- including those of former House Majority Leader Richard Gephardt and Episcopal Bishop Gene Robinson -- we discover how insightful people of faith handle the realization of having a gay child. Informed by such respected voices as Bishop Desmond Tutu, Harvard's Peter Gomes, Orthodox Rabbi Steve Greenberg and Reverend Jimmy Creech, FOR THE BIBLE TELLS ME SO offers healing, clarity and understanding to anyone caught in the crosshairs of scripture and sexual identity.

I can't recommend this excellent film enough. Would make a great Xmas gift for the religious folks on your list who still have a hangup about Christianity and gayness.

A couple of study guides are available here for group discussion, too.
