It does count. Marriage is ordained of God. Obviously the antis like to look at the period of 50 years of Polygamy in the early LDS church to tell us what we believe, and they ignore the end of it over a hundred years ago, they ignore the admonition that it’s up to the Lord to command to raise up seed unto him and build up his people, they also ignore the sanctity of Marriage that the LDS view. They also ignore that LDS marriages that happen in the temple have the lowest divorce rates in the US. They also ignore that repeated commandments against adultery, fornication, lasciviousness, and sexual perversions in any way. Those are no no’s in the LDS faith, and require serious repentance when people do them.
My argument is that polygamy is never right, not now, not a hundred years ago, not ever.
All those people in the Bible that you mentioned were sinners, men of God but still sinners.
Just because they practiced it doesn't mean they were right in doing so.
Sarah and Abraham is the prime example. She was attempting to ‘help’ God by giving her maid to Abraham. She doubted she could have a child. That was wrong. And Hagar was only property. She belonged to Sarah. Abraham having a child with Hagar was not ordained by God. It was all Sarah's stupid idea.
That is what those poor women in Texas are. Property.
