What about Polygamy in the Bible? Abraham, Isaac?, Jacob not to mention David, Solomon and many others.
I’m not promoting polygamy and would personally abhor it, but If we are going to say that God only endorses monogamy we have to look at biblical history.
The Old Testament, clearly illustrates examples of God condoning polygamy in the past.
You're a Mormon, right? Don't know if you learned that in your church, but it is absolutely wrong.
Because something exists in the Old Testament doesn't make it "condoned by God." David committed murder and adultery; were they condoned by Him?
God didn't approve of divorce because He handed down guidelines on when it was & wasn't permitted. Just as Jesus said, divorce comes from the hardness of man's heart. It has nothing to do with God's original plan, which was one man joined to one woman.
Deuteronomy 17:17 expressly forbids multiple wives for kings. Why would God approve them for anyone else? Also, in the New Testament, marriage partners are always referred to in the singular---"husband" and "wife". Never more than one wife.
