While the Church of England is considering this, it might take time to explain why it will only marry divorced people in exceptional circumstances and says that the local priest may refuse, on grounds of conscience, to do so at all.
It's hardly surprising that it takes the stance it does on gay marriages when it thinks that way about heterosexual ones.
The Church and Islam think that homosexual sex is against God's law, but the Church is mealy-mouthed about it and does not condemn active homosexuals. It prefers to complain that it should not be made to conduct gay marriage services, something which no proposed law would make it do.
I approve of 'gay marriage' and see no reason why there should be a semantic argument about marriage. Words change their meaning by usage. What other word is there to describe it?
