Saint Raphael is one of the Archangels, and listed as one of the 7 who "stand before the lord"
Hebrew: רְפָאֵל (God has Healed or God Heals)
In the book of Tobi, Saint Raphael travels alongside Tobit's son, Tobiah. He initially refers to himself as "Azarias the son of the great Ananias" and is credited with driving the evil spirit Asmodeus from Sarah and restoring Tobit's visions so that Tobit could see the light of Heaven and receive all good things through his intercession.
Though not explicitly mentioned by name, Saint Raphael is generally recognized as the Archangel mentioned in John 5: 4:
For an angel went down at a certain time into the pool and stirred up the water; then whoever stepped in first, after the stirring of the water, was made well of whatever disease he had.
Saint John of God was visited often by the Archangel in person. Saint John founded the Brothers Hospitallers of Saint John of God, and some facilities are locally called "Raphael Centers". Saint Maria Francesca of the Five Wounds also reported visitations of the Archangel.
The feast day of Saint Raphael was included in the General Roman Calendar for the first time in 1921 for celebration on October 24th. The celebration was joined with the celebrations of Saint Michael and Saint Gabriel in 1969 for September 29th (also known as Michael's Mass). The Coptic Orthodox Church celebrates his feas on Kouji Nabot 3 and Koiak 13.
