Do you remember a while back when the media in America was asking whether marriage was only between a man and a woman? Even some of the best and brightest in Christianity were duped into answering a question that, even in its formation, limited the Christian definition of marriage.
Marriage being a trinity between God, man and woman is what separates a Christian definition of marriage from every version or perversion of marriage any culture or individual can decide upon.
From a Christian perspective, marriage is not and never has been between a man and a woman. A Christian marriage, as shown in Genesis 1 and 2, is between God, a man and a woman.
When a culture or individuals remove God from marriage, anything can occur. After all, in some cultures, beating one's wife is a normal practice. Regardless of cultural belief, when you or I believe that marriage is just between a man and a woman, the fruit of this secular idea will show up in our marriages.......
Newsflash: Marriage is not just between a man and a woman; it is between God, a man and a woman. He makes the rules, not the humans in the marriage.
