20. In the Liturgy, Mary is celebrated as "united to Joseph, the just man, by a bond of marital and virginal love."(³¹) There are really two kinds of love here, both of which together represent the mystery of the Church-virgin and spouse-as symbolized in the marriage of Mary and Joseph. "Virginity or celibacy for the sake of the Kingdom of God not only does not contradict the dignity of marriage but presupposes and confirms it. Marriage and virginity are two ways of expressing and living the one mystery of the Covenant of God with his people."(³²) the Covenant which is a communion of love between God and human beings.

Through his complete self-sacrifice, Joseph expressed his generous love for the Mother of God, and gave her a husband's "gift of self." Even though he decided to draw back so as not to interfere in the plan of God which was coming to pass in Mary, Joseph obeyed the explicit command of the angel and look Mary into his home, while respecting the fact that she belonged exclusively to God.

On the other hand, it was from his marriage to Mary that Joseph derived his singular dignity and his rights in regard to Jesus. "It is certain that the dignity of the Mother of God is so exalted that nothing could be more sublime; yet because Mary was united to Joseph by the bond of marriage, there can be no doubt but that Joseph approached as no other person ever could that eminent dignity whereby the Mother of God towers above all creatures. Since marriage is the highest degree of association and friendship involving by its very nature a communion of goods, it follows that God, by giving Joseph to the Virgin, did not give him to her only as a companion for life, a witness of her virginity and protector of her honor: he also gave Joseph to Mary in order that he might share, through the marriage pact, in her own sublime greatness."(³³)
