Polygamy was allowed in the Old Testament. It wasn't God's plan for man and woman though, yet it was allowed. There are sects that believe polygamy is still allowed. Do you think this is something that the United States will someday legalize?
IMO....
1. The secular state has nothing to do with marriage and should stay out of it. Marriage is a ANCIENT and UNIVERSAL institution (much older than the USA or any state thereof!), I believe created by God but in any case, not by the Supreme Court of California or the USA.
2. The USA has recently stripped the institution of any meaning. Since "marriage" now is WHATEVER the current US Supreme Court TELLS YOU it means (Not God.... not soceity..... not history..... not humanity), then it has no objective meaning. I see no reason why the USA cannot (and perhaps will not) declare "marriage" to be any group where there is anything. Thus, a little old lady and her Pekingese is "marriage." The group of high school cheerleaders is "marriage." Two rabbits is "marriage." Why not? "Marriage" has no meaning, only what the current Supreme Court of the United States of America itself CURRENTLY says - it self trumping all history, humanity, God. I see NOTHING to keep the USA from saying polygamy is "marriage". Nothing that should keep it from permitting boys from marrying their mom (and dad, too)..... Nothing from keeping a woman from marrying her 15 cats. After all, "marriage" only is whatever The Supreme Court of The United States of America itself currently says. Nothing more, nothing other.
Yes, I think in a few decades the US Supreme Court will consider ANY combination of people (and probably mammals) to be "marriage" Forget history.... forget God.... forget religion..... forget the church.... forget families.... all that matters is the absolute power of The Supreme Court of The United States of America to redefine anything to anything it currently likes. Reasonably, I think it has no basis to not permit polygamy - and any other combination, invention.
But, the good news IMO is that the Supreme Court, for all it's obsession over the power of itself, cannot so easily destroy what God has created and what at least 10,000 years of UNIVERSAL human experience has embraced. Sure..... old ladies and all their cats MAY choose to call their relationship "marriage" and the USA may agree..... but I suspect MOST people in the world won't. Modern secular government's war on religion - now aimed at THE most basic of all human institutions - will have only a very limited success, IMO. I hope. Marriage/family is older, bigger than the USA... I suspect it will even outlast it?
