Joseph of Nazareth, also called Joseph the Betrothed and Saint Joseph, was the legal father of Jesus of Nazareth (Matthew 1:16; Luke 3:23) and the husband of Mary. However, according to the bible, he is not the biological father of Jesus. According to Christian tradition Mary conceived of Jesus through divine means and not through human effort. Not much is known of Joseph except that he was "of the House of David" and lived in the town of Nazareth. His date of death is unknown, though he was still living when Jesus was 12 years old. In the Roman Catholic tradition (see Catholicism), he is the patron saint of workers and has several feast days.
Spiritual Significance of Luke 3:23
The spitirtual significance of the comment in Luke 3:23 "as was supposed" (in some translations "so it was thought") (of Joseph's fatherhood) is in the fact that God is letting us know that Jewish society did NOT understand the real paternity of Jesus... that of the Holy Spirit... thus was incapable of understanding His ministry... as was certainly exhibited by the actions and attitudes of the scribes, Pharisees, lawyers, etc. to whom parentage and ancestry had become a cumbersome and burdensome legalism that blighted New Testament Judaism. They completely missed the Messianic note in the lists of both Matthew and Luke... except for a very small minority like Nicodemus and Joseph of Arimathea, eventually...or Simeon or Anna of Luke 2.
