I haven’t been able to research this too much, but I’ve read that most Catholic scholars nowadays don’t consider the book of Tobit to be a strictly historical book, but rather a long parable that reveals a religious truth. If it is a parable, then how do we know that Raphael is really one of the archangels, since he’s not mentioned explicitly in scripture except for the book of Tobit? Have there been any miracles attributed to his intercession that have been approved by the Church?
Well, here’s one answer from a historical POV.
The whole science of angelology developed during the Exile and in post-exilic Judaism, when there was apparently a serious interest in the up-to-then still rather vague idea of the anonymous messengers of God that fleetingly appear in older texts. As a result, certain angels came to take on a more particular significance and developed unique personalities and roles, even names (the 3rd century rabbi Simeon ben Lakish once said that all the specific names for the angels were brought back by the Jews from Babylon). These angels were generally believed to have rank amongst the heavenly host: thus, they are known as ‘arch-angels’.
What’s interesting is, many Jewish sources from this period and afterwards - aside from Tobit, you also have the Dead Sea Scrolls, rabbinic and Kabbalistic tradition, the Book of Enoch, the
Life of Adam and Eve (aka
Apocalypse of Moses), as well as a number of amulets and talismans - give the number of these high-ranking messengers as seven. Most agree on the names of at least three: Michael, Gabriel,
and Raphael. This was one of the things that we Christians have inherited from our Jewish forebears.
There is some confusion about the rest, as many sources do not agree on their names: you have angels like Uriel, Sariel, Raguel, Remiel, Zadkiel, Jophiel, Haniel or Chamuel in Jewish tradition; later Christian sources expand the list of candidates further by giving other names such as Phanuel, Simiel, Zarachiel, Barachiel, Jegudiel/Judiel, etc. (!!) So at least we can safely say that most people already called one of the seven ‘Raphael’ from the earliest days.
