One aspect of the show that has always fascinated me was the way that "Lost" avoided being cast into the shadow of one religion. However, the finale, changed this. Although the stain-glass window in the church was intended to symbolize the multi-religious style of the show, things like "Christian Shepard" and the white light at the end of the show made it very clear that Christianity is in fact the religion of "Lost". This was a major weakness in the sixth season for me. I am curious to see how other people have dealt with what I see as one of the flaws of "Lost".
