1 Corinthians 7:2 "Nevertheless, to avoid fornication let every man have his own wife, and let every woman have her own husband."
Fornication-A single person, never married, having someone's Biblical (covenant) companion.
It seems to be slowly developing in the minds of the people that when a man who has no living wife marries a woman with a husband that that man will be free to divorce this woman and be free to marry another. The man is guilty of fornication and may marry another but the woman is bound to her first companion.
