"The apostle Paul added to the teachings of Jesus what is called the "Pauline privilege." According to this concept, Paul taught that if an unbelieving spouse leaves a believer, the believer is not bound to the marriage relationship, but is free to remarry" (1 Corinthians 7:15). And some people recognize such a thing as a "constructive desertion," which would be when a husband so brutalizes his wife that it is impossible to live with him any longer; or when a wife has so harassed, or brutalized her husband that it becomes impossible for him to stay with her. When that happens, whether or not the person actually moves out, the situation is the equivalent of desertion, and divorce and remarriage are permissible.Except for these reasons, there is no justification given in the Bible for divorce. No grounds exist for divorce on the basis of incompatibility, lack of love, or differing career goals. Frankly, it seems impossible that two born-again Christians who are dedicated to serving Jesus Christ can find any grounds for divorce.
Obviously, when a person who does not have biblical grounds for divorce remarries, he or she is technically committing adultery."
