When the Pope went to Africa back in March, he spoke about how St. Joseph reminds us of the value and meaning of priestly vows. Just a couple excerpts (This comes from the Vatican Information Service):
Speaking to the crowd and to His disciples, Jesus declared: 'You have only one Father'", said the Pope in his homily. "There is but one fatherhood, that of God the Father, the one Creator of the world, 'of all that is seen and unseen'. Yet man, created in the image of God, has been granted a share in this one paternity of God. St. Joseph is a striking case of this. ... He is not the biological father of Jesus, Whose Father is God alone, and yet he lives his fatherhood fully and completely. "To be a father means above all to be at the service of life and growth", he added. "St. Joseph, in this sense, gave proof of great devotion. For the sake of Christ he experienced persecution, exile and the poverty which this entails".
When Mary responded to the angel's call, she was already betrothed to Joseph, the Holy Father observed, adding: "In addressing Mary personally, the Lord already closely associates Joseph to the mystery of the Incarnation. Joseph agreed to be part of the great events which God was beginning to bring about in the womb of his spouse". Taking Mary into his home "he welcomed the mystery that was in Mary and the mystery that was Mary herself. He loved her with great respect, which is the mark of all authentic love. Joseph teaches us that it is possible to love without possessing". Drawing inspiration from Joseph, all men and women can, then, "come to experience healing from their emotional wounds, if only they embrace the plan that God has begun to bring about in those close to Him".
