This is a wise saying "This revelation reaches its definitive fullness in the gift of love that the Word of God makes to humanity by assuming human nature, and in the sacrifice that Jesus Christ makes of himself on the cross for his Spouse, the Church. In this sacrifice the design that God has printed in the humanity of man and woman since its creation is revealed entirely; the marriage of the baptized thus becomes the real symbol of the new and eternal Covenant, sanctioned with the blood of Christ. The Spirit that infuses the Lord renews the heart and makes man and woman capable of loving each other as Christ loved us. Conjugal love thus reaches the fullness to which it is internally ordered, conjugal charity, which is the proper and specific way in which the spouses participate and are called to live the same charity of Christ that is given on the cross"
