Archangel Raphael is the archangel of the fifth ray of truth, wholeness, healing, science, precipitation, the abundant life, music and mathematics.
The name “Raphael” means “God has healed,” or “the Medicine of God.” One Jewish text says he revealed to Noah the curative power of plants; another tells how he healed a blind man and bound a demon. Catholics revere him as the angel who healed the sick at the pool of Bethesda.
The Book of Enoch tells us that his responsibilities include healing the diseases and wounds of men. A Jewish tradition names him as one of the three archangels who appeared to Abraham on the plains of Mamre. In fact, it is believed that it was Raphael who endowed Sarah, Abraham’s wife, with the strength to conceive when she was past childbearing age. Raphael is also known as the patron of travelers.
In the Book of Tobit, Raphael, disguised as a knowledgeable traveler, accompanies Tobit’s son as his guide on a long journey. At the end of the story, Raphael reveals his true identity and explains that God sent him to test the faith of Tobit and his son. They passed their tests and received great blessings of healing and abundance. The story of a fish figures prominently in the story of Tobit, hence the fish in Raphael's left hand.
