this is a big downgrade for social standards....if two men can marry each other, than there is no reason why daddy and dtr can't marry, why sister and brother can't marry, or why two brothers can't just get married....
there has to be right, wrong......there has to be social tradition....there has to be social norms....
Those things are only valuable, and only have truth, if they are grounded in the one true God and the glory of Jesus Christ. Apart from that they are meaningless and worthless, just worldy ambitions which are of no benefit.
