Church of England unveils a two-in-one wedding and baptism liturgy today as it seeks to make peace with families "living in sin"
If they can do joint weddings and baptisms, why not same-sex marriages? Otherwise, it's one rule for the heterosexuals and a different rule for LGBT people. According to fundamentalists, the Bible says not to have sex outside marriage (in fact it doesn't say any such thing, though it implies it in several places). Certainly that's been the teaching of the Church of England, alongside its insistence on heterosexual sex only. So if it can countenance this new "hatch-and-match" liturgy, which doesn't fit in with its teaching, why not do same-sex marriages as well? Or change the teaching to something more sensible.
Personally I think Christians should stop worrying about people's sex lives and worry about climate change, war, mass species extinction, etc., which are actually life-threatening.
