Saint Raphael is one of seven Archangels who stand before the throne of the Lord. He was sent by God to help Tobit, Tobiah and Sarah. Tobit was blind and Tobiah's betrothed, Sarah, had seven bridegrooms perish on the night of their weddings. Raphael accompanied Tobiah into Media disguised as a man named Azariah. Raphael helped him through his difficulties and taught him how to safely enter marriage with Sarah. Tobiah said that Raphael caused him to have his wife and that he gave joy to Sarah's parents for driving out the evil spirit in her. He also gave Raphael credit for his father's seeing the light of heaven and for receiving all good things through his intercession. Raphael, Michael and Gabriel are the only Archangels mentioned by name in the bible. Raphael's name means God heals. This identity came about because of the biblical story which claims that he healed the earth when it was defiled by the sins of the fallen angels in the apocryphal book of Enoch. Raphael is also identified as the angel who moved the waters of the healing sheep pool.

He is the patron of the blind, of happy meetings, of nurses, of physicians and of travelers. His feast day is celebrated on September 29th.
