It was mentioned here and at Victor Reppert's Christian philosopher's blogsite that former Christian Gareth McCaughan had left the fold and had composed an intelligent and calmly worded testimony about having done so. (Gareth and Vic used to discuss Vic's philosophical arguments in a British usenet group back when Gareth was still a Christian.) I recently heard from Gareth that a friend of his, Paul Wright, left the fold before he did and that Wright had composed a testimony of similar intellectual equipose that can be read here.
