St. Joseph was the husband of Mary and the foster-father of Jesus.
We know he was a carpenter, a working man, for the skeptical Nazarenes ask about Jesus, "Is this not the carpenter's son?" (Matthew 13:55). He wasn't rich for when he took Jesus to the Temple to be circumcised and Mary to be purified he offered the sacrifice of two turtledoves or a pair of pigeons, allowed only for those who could not afford a lamb (Luke 2:24).
We know Joseph was man of faith, obedient to whatever God asked of him without knowing the outcome. When the angel came to Joseph in a dream and told him the truth about the child Mary was carrying, Joseph immediately and without question or concern for gossip, took Mary as his wife. When the angel came again to tell him that his family was in danger, he immediately left everything he owned, all his family and friends, and fled to a strange country with his young wife and the baby. He waited in Egypt without question until the angel told him it was safe to go back (Matthew 2:13-23).
We know Joseph respected God. He followed God's commands in handling the situation with Mary and going to Jerusalem to have Jesus circumcised and Mary purified after Jesus' birth. We are told that he took his family to Jerusalem every year for Passover, something that could not have been easy for a working man.
Since Joseph does not appear in Jesus' public life, at his death, or resurrection, many historians believe Joseph probably had died before Jesus entered public ministry.
Joseph is the patron of the dying because, assuming he died before Jesus' public life, he died with Jesus and Mary close to him, the way we all would like to leave this earth.
A symbol of St. Joseph is carpenter tools, which I have attempted to represent in this 12" x 12" quilt block. To download the free pattern: Quilt Block in Honor of St. Joseph
