Joseph is a figure in the Gospels, the husband of Mary, the mother of Jesus and is venerated Saint Joseph in some Christian traditions. Christian tradition places Joseph as Jesus' foster father. Some historians state that Joseph was Jesus' father. Some differing views are due to theological interpretations versus historical views.
The Pauline epistles make no reference to Jesus' father; nor does the Gospel of Mark. The first appearance of Joseph is in the gospels of Matthew and Luke. Each contains a genealogy of Jesus showing ancestry from king David, but through different sons; Matthew follows the major royal line from Solomon, while Luke traces another line back to Nathan, another son of David and Bathsheba. Consequently, all the names between David and Joseph are different. According to Matthew 1:16 "Jacob begat Joseph the husband of Mary", while according to Luke 3:23, Joseph is said to be "[the son] of Heli". Some scholars reconcile the genealogies by viewing the Solomonic lineage in Matthew as Joseph's major royal line, and the Nathanic lineage in Luke to be Mary's minor line.
Joseph is venerated as a saint in the Catholic, Eastern Orthodox, Oriental Orthodox, Anglican, Lutheran and Methodist faiths. In Catholic and other traditions, Joseph is the patron saint of workers and has several feast days. He was also declared to be the patron saint and protector of the Catholic Church by Pope Pius IX in 1870, and is the patron of several countries and regions. With the growth of Mariology, the theological field of Josephology has also grown and since the 1950s centers for studying it have been formed.
