I have a relative who was recently divorced, & is wondering if he has biblical grounds to remarry. Both he & his ex-wife are professing Christians. Here's his side of the story: While married, he committed adultery. He confessed it to his wife who decided not to leave him. About a year later, they separated due to marital problems. While separated, the wife committed adultery. He tried to reconcile the marriage, but she refused. She contended that she had biblical grounds for divorce due to his initial unfaithfulness. Do either of them have biblical grounds to remarry? If a spouse commits adultery, how long can the other spouse cling to Mt. 19:9 as grounds for divorce & remarriage? What if they both commit adultery, as in this case?
