Paul - first, it is not the altar of Christ - it is God's altar - there is a difference you know.secondly - I don't remember where in the bible it says anything about being fully clothed. In fact - nakedness and innocence are often related.
thirdly - you are descending to personal insults - without even knowning the people whom you are addressing.
This is suppossed to put a good face on Christian mission? Methinks you are shooting yourself in the foot.
