292. Christian marriage, as a reflection of the union between Christ and his Church, is fully realized in the union between a man and a woman who give themselves to each other in a free, faithful and exclusive love, who belong to each other until death and are open to the transmission of life, and are consecrated by the sacrament, which grants them the grace to become a domestic church and a leaven of new life for society. Some forms of union radically contradict this ideal, while others realize it in at least a partial and analogous way. The Synod Fathers stated that the Church does not disregard the constructive elements in those situations which do not yet or no longer correspond to her teaching on marriage.314
