Marriage is an enduring and exclusive partnership between one man and one woman for the mutual exchange of love and for the procreation and education of children.

Between those who have been baptized, a valid marriage is a sacrament. Every valid, sacramental marriage that has been consummated is indissoluble. This is the law of God according to the evidence found in the Old Testament, the Gospels of St. Matthew, St. Mark, and St. Luke, the writings of St. Paul, and Christian tradition.
