Matthew 5:32 but I say to you that everyone who divorces his wife, except for the reason of unchastity, makes her commit adultery; and whoever marries a divorced woman commits adultery.
Commentary: Jesus said that divorce is not permissible except for unfaithfulness. This does not mean that divorce should automatically occur when a spouse commits adultery. The word translated "unchastity" implies a sexually immoral life-style, not a confessed and repented act of adultery. Those who discover that their partner has been unfaithful should first make every effort to forgive, reconcile, and restore their relationship. We are always to look for reasons to restore the marriage relationship rather than for excuses to leave it.
