Saint Joseph was chosen by God to be Jesus's father on earth. God knew that Jesus would need a foster father to raise him and teach him. The Bible tells us that he was a 'just man.' That means he was a good man, honest, fair, and God-loving. After an angel told Mary that she would be the Mother of God, Saint Joseph wondered what to do. An angel appeared to him in a dream and told him not to worry, that the child was the Messiah, conceived by the Holy Spirit. Joseph was to be her husband and protect the child as He grew. Joseph decided to trust the angel and God. He married Mary and took her into his home.
After Jesus was born in Bethlehem, the angel appeared to Joseph again, warning him that the Child was in danger. Joseph obeyed the angel's message again, and took his family to Egypt to escape from Herod's soldiers. After many years, the Holy Family finally returned to their home village of Nazareth.
As the Bible tells us, Saint Joseph was descended from the royal house of David. A village carpenter of Nazareth, he was chosen among all men to be the husband and protector of the Virgin Mother of Jesus Christ. To his loving care was entrusted the childhood and youth of the Redeemer of the world. He reveals to us the perfect model of Christianity through his purity of heart, patience, and fortitude. Poor in worldly possessions, he was rich in grace.
Because Saint Joseph was the representative of our Heavenly Father on earth, because he acted as Christ's father in His life on earth, he is the divinely appointed head of the Holy Family. The Holy Family; of Saint Joseph, The Blessed Mother and the Son of God is the beginning and the model for the great Family of God, His Church here on earth. In this way, Saint Joseph is father to all of us. A model for fathers, Saint Joseph is invoked as a protector of the family. A carpenter by trade, he has been declared the patron saint of all working people, of craftsmen and of the poor. He is the model of a perfect Christian life and the patron of a happy death. His patronage also extends over the Mystical Body of Christ, over the Christian family, the Christian school, and all individuals who in their need appeal to his charity and powerful intercession, especially at the hour of death.
