"Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill" (Matthew 5/17)Insofar as Mosaic laws were subsequently overturned, St Paul did that as he tried to make the Christian religion more palatable to the Romans, but even he reiterated the prohibitions on homosexuality. That some people who think of themselves as Christian are in step with the rest of us on LGBTQ issues of equality and human rights is encouraging and welcome, but to claim such views are compatible with Christianity is false.
I think the Anglican Church will have to make a decision sooner or later on this issue. They must either admit that scripture is largely outdated and no longer a reliable guide to morality or take a stand and make the inevitable split with secular society.
Some may see this as a problem; I see an opportunity in the making.
