The only archangels that the Bible specifically names are Gabriel, Michael and Raphael. Various apocryphal writings (books which the Christian Church rejected early on as not being divinely-inspired) and rabbinical literature give proper names to four other archangels, these being Uriel, Raguel, Sariel, and Jeremiel.
The apocryphal books of Enoch and Edras, as well as certain apocryphal gospels, contain many stories about the archangel Uriel. In the Book of Enoch, it is Uriel who warns Noah of the upcoming worldwide flood. Uriel also shows Enoch a vision of the punishment of those angels who rebelled against God. In the writings of Edras, God sends Uriel to answer various questions put to him by the prophet Ezra. In some apocryphal gospel writings, Uriel saves John the Baptist from King Herod's slaughter of the Holy Innocents. The archangel Jeremiel also plays an important part in some of these apocryphal writings. Some Christian traditions, such as Eastern Orthodoxy, recognize Uriel and Jeremiel as saints.
The Catholic Church restricts devotions calling upon the specific names of angels and archangels to those specifically found in the canonical Bible, these being Michael, Raphael and Gabriel. Raphael and Gabriel are the two archangels who receive the most treatment in Scripture. Gabriel is most famous for being the one to announce the birth of Jesus to the Virgin Mary.
