How long before straight marriage is outlawed?
I am sure they are already trying to figure out how to do that.
It seems that the Catholic church is considering getting out of the civil marriage business. Relevant radio, First Things, and a few other sources I stumbled on have had articles and shows dedicated to saying “Hey, we can leave State marriage along, and focus on the religious sacrament”.
I expect quite a few non Catholic denominations to follow suit. In other words, the Church is getting out of the marriage business just like it got out of the hospital, adoption, and aid business.
