The Bible’s answer
The Bible does permit divorce. However, Jesus identified only one acceptable reason to end a marriage, stating: “Whoever divorces his wife, except on the ground of fornication [sex outside of the marriage], and marries another commits adultery.”—Matthew 19:9.
God hates a deceitful, treacherous divorce. He will personally hold accountable those who frivolously leave their mate, especially when they do so with the motive of taking another partner.—Malachi 2:13-16; Mark 10:9.
