Thorough his sacrifice on the cross, Jesus established a new and eternal covenant between God and human beings. This covenant is a covenant of love, in which, Christ the bridegroom, purifies his bride, the Church (the people of God) by sacrificing his own life. Furthermore, He maintains an intimate communion with his people by feeding them with His sacrificial body and blood. Through this communion, his people not only establish a personal relationship with him, but also make him the Lord of their lives. Therefore, at the celebration of His Last Supper when we re-enter his sacrifice on the cross, we are celebrating the wedding feast of the Lamb in which He gives himself completely to us and we by receiving him accept his life as ours. Since, how we love God goes hand in hand with how we love our fellow human beings, the above form of love must also be present in marriage; which is also a covenant of love. Therefore a husband must completely give himself to his wife and the wife must completely accept him as her life. Furthermore, just as God is always faithful to his covenant with us although we betray him and are unfaithful to him by our sins; we too must faithful to our covenant with our spouse even if there is betrayal and unfaithfulness.
