I still wonder what's being "celebrated". Do we "celebrate" family members who are bank robbers? murderers? shacked-up? Thrice-married-twice-divorced-never-annulled? abortionists? prostitutes? Why then celebrate sodomites?
We might rightly celebrate those who by the Grace of god repent, and abandon intrinsically disordered lifestyles. Indeed, there's more rejoicing in Heaven over the repentance of one such thant over 99 who have no need of repentance.
