I don't think it's weird at all, even though I am not a Christian. I have spoken about religion in my therapy, even though my T is not of the same faith. I have been harmed by religious people and in religious contexts and needed a safe place to talk about that. I have also studied a little Buddhism and have found incorporating these ideas into my therapy useful. I'm not very clear on the line between spirituality and religion, but my T's have welcomed discussion of all these things as obviously they are a part of who we are as humans. I'm sure that issues don't arise for everyone as they have for me, but I think considering yourself in relationship to faith and spirtuality is a worthwhile inquiry in therapy.
