"...the same yesterday, today, and forever...." (Heb. 13:8)
New Testament v. Old Testament or Christian v. pre-Christian era is a false distinction.
He created Adam. How many wives did He create from that rib in Adam's side?
Speaking of Himself: "And He answered and said to them, "Have you not read that He who made them at the beginning 'made them male and female,' and said, 'For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh' ? So they are no longer two, but one."" (Matt 19: 4-6)
Does the Creator of the Universe say united to his "wife" or "wives"?
God's patience with man's disobedience should not be interpreted by you as His endorsement of sin, or what defines what is His perfect will for man as He created him, designed him, and established the marriage relationship for him.
FReegards!
Religion does not matter in court...
Reynolds v. United States in 1878 defined marriage as one man and one woman.
Beautifully said.
