So Christian women are not allowed to divorce.
1 Corinthians, Chapter 7:10
But unto the married I give charge, [yea] not I, but the Lord, That the wife depart not from her husband
And Christian men are not allowed to divorce.
Mark, Chapter 10:11
And he saith unto them, Whosoever shall put away his wife, and marry another, committeth adultery against her:
Is the following adhered to, by Christians:
The New Testament associates remarriage after divorce and adultery. Marriage is a lifelong covenant between a man and a woman. Divorce does not break the bond, so remarriage is viewed as adultery except in cases where unfaithfulness was the reason for the divorce (Matt. 5:32; Mark 10:11-12). The marriage bond is broken by death (Rom. 7:3; 1 Cor. 7:39).
The Old Testament support pologamy; because the New Testament upheld it also.
"Do not think that I have come to abolish the Law (the Old Testament) or the Prophets; I have not come to abolish them but to fulfill them. I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke or a pen, will by any means disappear from the Law (the Old Testament) until everything is accomplished. (Matthew 5:17-18)"
Now unless if you've got something to show that Christians still follow all the teachings of the New Testament, regarding marriage, then your presentation is false.
