We all know Saint Joseph as the foster father of Jesus. But there are a lot interesting parallels between Saint Joseph, and someone you may not be as familiar with—Joseph the Patriarch of the Old Testament. Let’s dive a little deeper into some similarities between Saint Joseph and his Old Testament ancestor of the same name.
Foster Father? True…but False
It’s true that St. Joseph is technically the foster father of Jesus. Even the Litany to St. Joseph refers to him as “Foster father of the son of God.” But while that title is technically correct, it’s also a bit inaccurate because it diminishes, or denies Joseph’s rightful role and authority in the life of Jesus, and it denies Jesus of his hereditary lineage as the son of David—something that is essential to his nature as the Messiah. Here’s why.Our Lord’s natural, biological mother is Mary, but he has no natural (biological) father. Hence St. Joseph becomes Jesus’ foster father because he has no biological connection to Jesus. But in truth, Joseph is never referred to in scripture as the “foster father” of Jesus. He is, instead, referred to as Jesus’ father by Gospel writers who knew very well that St. Joseph had no biological connection to Jesus. Here’s one example, when Mary and Joseph find Jesus in the temple after searching for him for three days:” Joseph is never referred to in scripture as the foster father of Jesus”
“When Jesus’ parents found him, they were astonished. His mother said to him, ‘Son, why have you done this to us? Your father and I have been anxiously searching for you.” Here scripture says, “Jesus’ parents…” not “His mother and stepfather.” Mary doesn’t say, “Joseph and I have been anxiously searching for you,” but calls him “your father.” [Article Continues Below]So why is Joseph called Jesus’ father rather than stepfather or foster father? Jesus’ biological mother is Mary. St. Joseph, being lawfully married to Jesus’ mother (meaning by divine law, not merely human law),becomes the lawful father of Jesus. He is Jesus’ father in every way except biology. St. Joseph has a father’s authority over Jesus, a father’s responsibility to Jesus, and by Jewish law and tradition, Jesus derives his hereditary lineage from his father—not his mother—which is why, as Joseph’s son, Jesus is the son of David (Joseph is of the lineage of David.). It was always known by the Jews that the messiah would be of King David’s line—the “son of David”. If Joseph, who is descended from David, is not the lawful husband of Mary, he can’t be the lawful father of Jesus, and Jesus could not be the “son of David” who inherits the throne of King David. This is why while St. Joseph is technically the “foster father of the Son of God”, he is lawfully Jesus’early father, and is referred to accordingly in the Gospel.s
