When a man and woman marry each other in the Church, they are not joined sacramentally until the marriage is consummated, that is, until they partake of sexual intercourse. Most people think of the Sacrament of Holy Matrimony as only being administered once. I believe they are mistaken. The sacrament is enacted every time a married couple makes love. A husband’s seed is given to his wife, in whom it might "take root" and grow into another human being, another member of the domestic church.
Christ is the bridegroom of the Church. The marriage was not consummated until Christ died on the cross for our sins. Some people think that this sacrifice was manifested only once. I believe they are mistaken. The sacrifice is enacted every time a member of the Church receives the Sacrament of the Holy Eucharist. God’s seed, grace, is given to members of the Church, in whom it might take root and grow into faith, a faith that enables us to go and make new disciples, new members of the Universal Church.
