The earliest reference to a system of seven archangels as a group appears to be in Enoch I (the Book of Enoch) which is not part of the Jewish Canon but is prevalent in the Judaic tradition, where they are named as Gabriel, Michael, Raphael, Uriel, Raguel, Ramiel and Sariel. While this book today is non-canonical in most Christian Churches, it was explicitly quoted in the New Testament (Letter of Jude 1:14-15) and by many of the early Church Fathers. The Ethiopian Orthodox Church to this day regards it to be canonical.
