By 'Divine Command' homosexuality is a Sin. And the penalty for homosexuality will be eternal torment in fire. It is blatantly obvious that the 'Word of God' commands all Christians to believe this. But many don't as they choose instead to simply pick and choose what they will and will not believe. The fundamentalists will continue to press their case, but I believe to no avail with 'Contemporary Christians'.
In my view, the more aggressively fundamentalists take their stand, on this and other issues, the more losses will happen more quickly in US Churches, both protestant and catholic. Being a secularist, of course that is fine by me. The trend appears it will continue in the US, away from dogmatic Religion and toward secularist/humanist, the same way it has in Europe, but the US has a lot of catching up to do to get down to the low percentages in Western European countries that identify themselves as religious - now well below 50% in some countries.
