We have heard one of those narratives today. For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh. So they are no longer two, but one flesh. Jesus refuses to play any legalistic games. God is for life.
Life is sexual.
Male and female seek to join together because God intended it so. When the two find each other, they become one flesh. It is God s purpose that this should happen, and humans should not seek loopholes with which to avoid the permanency of the marriage relationship. Jesus is against divorce, but this does not give us a legal basis by which to forbid divorce. Sometimes it is necessary.
