"Raphael is the protagonist of an entire book of the Bible. The archangel accompanies Tobias, the young son of Tobit and Anna, when Tobit asks Tobias to carry out a delicate mission that will require a long and dangerous journey"

"Raphael (רפאל, Hebrew for "God has healed," "God Heals" ) is the name of an archangel in Judaism, Christianity and Islam, who is said to perform all types of healings. Linked to his name is the Hebrew word for a doctor of medicine: Rophe, which has the same root word as Raphael.
Of the seven archangels in the angelology of post-Exilic Judaism, only Michael (Daniel 12:1) and Gabriel (Luke 1: 19-26) are mentioned by name in the scriptures that came to be accepted as canonical by all Christians. However, Raphael is mentioned by name in the Book of Tobit, which is accepted as canonical by Roman Catholic and Orthodox Christians."

"The seven angels were Raphael, Gabriel, Uriel, Michael, Izidkiel, Hanael, and Kepharel. These were the seven archangels, the princes of the angelic host, the only angels permitted to enter within the radiance of God’s glory (cf. Luke 1:19, where Gabriel describes himself as one that stands in God’s presence). These angels heard the prayers of the saints, brought the requests to God, and then stood ready to execute God’s answer. Raphael served as a guardian angel for Tobit, protecting him from death for burying Jews who had been massacred in Nineveh, and acting as his traveling companion in his journey from Nineveh to Ecbatana. Raphael’s chief function, however, was as a healer of men’s diseases. He cured the blindness of Tobit and expelled the demon from Sarah, the woman who later married Tobit’s son Tobias.
In the Book of Enoch, Raphael and Michael are commissioned to punish the fallen angels, the angels who had married human wives in the time of Noah."

"Raphael was never a human being who lived on Earth. Instead, he has always been a heavenly angel. He was declared a saint in honor of his work helping humanity."
