Hello,
Saint John the Baptist is the greatest of the Old Testament Prophets - and he lived on the verge of the dawning of the New Testament. That is what is meant by the verse that calls him the greatest born among women.
I cast my vote for the greatest Saint after the Virgin Mary for Saint Joseph, her most chaste spouse.
In an article written by Father Basil Cole, O.P., he writes:
While Redemptoris Custos reminds us that there is a kind of primacy of the interior life, it clearly indicates that for Joseph he was “in daily contact with the mystery ‘hidden from ages past,’ and which ‘dwelt’ under his roof…” (25a). If each act of Christ’s human actions caused grace for us either by merit or by a certain efficacy, then the floods of graces had to be given to Joseph, not only for his mission as minister to Jesus and Mary, but also for his daily spiritual life in general. Joseph’s fatherly love was also influenced by Jesus’ filial love, which in turn prevailed upon the fatherly affection of Joseph. Each minute spent with Jesus was like receiving a continuous Holy Communion. Thus, Joseph’s contemplative love of divine truth overflowed into his life of selfless love for his wife and son, and reciprocally, his mission-driven life overflowed into this contemplative life.
Because of these factors, Josephologists assert that Saint Joseph deserves not simply dulia or the ordinary respect and reverence due to the saints and angels but proto-dulia because he is probably the highest of the saints and angels, after his wife, by reason of his closeness to Jesus and Mary. In some sense, all holiness of the New Covenant flows from this marriage as the recipient of the Incarnation. In some ways Joseph participates in the dignity of Jesus and Mary, which in turn evoked many graces for his life. Leo XIII wrote in the encyclical letter Quamquam Pluries that Joseph protects and defends “with his heavenly patronage the Church of Christ” (28b). Given the fact that he guided and protected the Holy Family, the logic of things is such that in heaven he would do precisely the same for the mystical body of Christ on earth.
Therefore, the more we love, revere and honor him, the more we dispose ourselves to receiving many graces from his Son through Mary. Just as Jesus and Mary depended upon him, we by praying to Joseph imitate them. His intercession for us increases as we love him, and so he facilitates our growth in the life of the Spirit making it somewhat easier as we surrender to his role here as our patron. Devotion to him does not lessen our love for Mary and Jesus, but rather offers us new possibilities of loving his Son and Mary even more. Redemptoris Custos reminds us that the great mystic, Saint Teresa of Jesus, promoted devotion to Saint Joseph precisely because she wanted to become an authentic contemplative (25a).
