I think the point where I get hung up if that we seem to often identify this as singularly the worst of sins, ye even unforgivable if you listen to some, yet in the end sin is sin. Bishops mishandling the truth about parishes they are assigning clergy to, and mishandling the truth about clergy to the parishes they assign them to may be thought of as telling the truth carefully, or it might just be lying. Would you call this sin? Would you see this as a better sin or a worser sin than someone who is Gay and open about it. I don't want to say that it is not sin, as much as anything I don't understand enough about it.
The scripture that does sit most on my heart is the often recited line form the Lord's Prayer:
forgive us our sins, as we forgive those who sin against us.
In terms of the function of the Church, be it mission or ministry, we need to be talking about Jesus a whole lot more, and dare I say it, what happens in someone else's bedroom a whole lot less.
When it comes to the subject of this thread, Gay Conversion Therapy being outlawed in Victoria, I support it. One of the reasons I support it is that it seems to me that much of the practice demeans the humanity of Gay people, and in so doing demeans the humanity of our whole society. Now we probably don't scientifically know absolutely if gayness is Nature or Nurture, or just a choice people make. Your arguments make some sense if it is simply choice, however if in some sense if it is Nature, and having spoken at depth to members of my own family who are now in single gender marriages, which certainly for them seems to be Nature, then surely we should be encouraging them to be the best person they can be.
Sometimes I think 'Don't Ask, Don't Tell' was a whole lot easier for all of us.
