The Hebrew word for a doctor of medicine is Rophe connected to the same root word as Raphael.
Raphael in ChristianityThe name of the archangel Raphael appears only in the Deuterocanonical Book of Tobit (Tobias). Tobit is considered canonical by Catholics, Orthodox and some Protestants. Raphael first appears disguised in human form as the travelling companion of the younger Tobias, calling himself "Azarias the son of the great Ananias". During the adventurous course of the journey the archangel's protective influence is shown in many ways including the binding of the demon in the desert of upper Egypt. After the return and the healing of the blindness of the elder Tobias, Azarias makes himself known as "the angel Raphael, one of the seven, who stand before the Lord" (Tobit, xii, 15). Compare the unnamed angels in John's Apocalypse viii, 2.
Regarding the healing powers attributed to Raphael, we have little more than his declaration to Tobit (Tobit, 12) that he was sent by the Lord to heal him of his blindness and to deliver Sarah, his daughter-in-law, from the devil (Asmodeus) that was the serial killer of her husbands. Among Catholics, he is considered the patron saint of medical workers and matchmakers, and may be petitioned by them or those needing their services.
As the main character of the Book of Tobit, which is included in the Septuagint but assigned an apocryphal status by Protestant churches, many Protestant groups do not acknowledge Raphael.
Raphael is rarely the patron of Christian churches. Some exceptions are St. Raphael's Cathedral in Dubuque, Iowa –- seat of the Roman Catholic Archdiocese of Dubuque, St. Raphael's Cathedral Parish in Madison, Wisconsin –- seat of the Roman Catholic Diocese of Madison, St. Raphael Parish Church in New Orleans, Louisiana [Roman Catholic Archdiocese of New Orleans], Saint Raphael's Parish Church, Stalybridge, Cheshire in the Roman Catholic Diocese of Shrewsbury, St. Raphael's church (and mission) in San Rafael, California, St. Raphael Catholic Community in Rockville, Maryland and Sankt Raphael in Garbsen, Germany.
He has made only a light impression on Catholic geography: Saint Raphaël, France and Saint Raphaël, Quebec, Canada; San Rafaels in Argentina, Bolivia, Colombia, Chile, Mexico, Peru, the Philippines and in Venezuela as San Rafael de Mohán and San Rafael de Orituco. In the United States, San Rafaels inherited from Mexico survive in California (where besides the city there are San Rafael Mountains), in New Mexico, and in Utah, where the San Rafael River flows seasonally in the San Rafael Desert.
In the New Testament, only the archangels Gabriel and Michael are mentioned by name (Luke, i, 19, 26; Epistle of Jude, 9). John 5:1-4, refers to the pool at Bethesda, where the multitude of the infirm lay awaiting the moving of the water, for "an angel of the Lord descended at certain times into the pond; and the water was moved. And he that went down first into the pond after the motion of the water was made whole of whatsoever infirmity he lay under". Because of the healing role assigned to Raphael, this particular angel is generally associated with the archangel.
Raphael is sometimes shown (usually on medallions) as standing atop a large fish or holding a caught fish at the end of a line. This is a reference to Book of Tobit (Tobias), where he told Tobias to catch a fish, and then uses the galbladder to heal Tobit's eyes, and to drive away Asmodeus by burning the heart and liver.
Raphael in IslamAccording to the Hadith, Israfil (Raphael in Arabic) is the Angel responsible for signalling the coming of Judgment Day by blowing a horn and sending out a "Blast of Truth". Unlike Jibrail(Gabriel) and Mikail(Michael), this archangel was not mentioned by name in the Quran.
