19. In the words of the "annunciation" by night, Joseph not only heard the divine truth concerning his wife's indescribable vocation; he also heard once again the truth about his own vocation. This "just" man, who, in the spirit of the noblest traditions of the Chosen People, loved the Virgin of Nazareth and was bound to her by a husband's love, was once again called by God to this love.

"Joseph did as the angel of the Lord commanded him; he took his wife" into his home (Mt 1:24); what was conceived in Mary was "of the Holy Spirit." From expressions such as these are we not to suppose that his love as a man was also given new birth by the Holy Spirit? Are we not to think that the love of God which has been poured forth into the human heart through the Holy Spirit (cf. Rm 5:5) molds every human love to perfection? This love of God also molds-in a completely unique way-the love of husband and wife, deepening within it everything of human worth and beauty, everything that bespeaks an exclusive gift of self, a covenant between persons, and an authentic communion according to the model of the Blessed Trinity.

"Joseph. . .took his wife; but he knew her not, until she had borne a son" (Mt 1:24-25). These words indicate another kind of closeness in marriage. The deep spiritual closeness arising from marital union and the interpersonal contact between man and woman have their definitive origin in the Spirit, the Giver of Life (cf. Jn 6:63). Joseph, in obedience to the Spirit, found in the Spirit the source of love, the conjugal love which he experienced as a man. And this love proved to be greater than this "just man" could ever have expected within the limits of his human heart.
