エノク書
In early Christianity, use of the Book of Enoch as a divinely inspired text was widespread, since the canon had not yet been established definitively in the Church. Church Fathers such as Justin Martyr, Athenagoras of Athens, Irenaeus, Clement of Alexandria, Origen, Tertullian, and Lactantius all speak highly of Enoch and contain many allusions to the Book of Enoch as well as in some instances advocating explicitly for the use of the Book of Enoch as Scripture. Because of the letter of Jude's citation of the Book of Enoch as prophetic text, this encouraged acceptance and usage of the Book of Enoch in early Christian circles. The main themes of Enoch about the Watchers corrupting humanity were commonly mentioned in early literature. This positive treatment of the Book of Enoch was associated with millennialism which was popular in the early Church. When amillennialism began to be common in Christianity, the Book of Enoch, being incompatible with amillennialism, started to be rejected widespread, and with the split of the Oriental Orthodox from the Catholic Church in the 5th century, use of the Book of Enoch was limited primarily to the Oriental Orthodox Church. Eventually, the usage of the Book of Enoch became limited to Ethiopian circles of the Oriental Orthodox Church. Another common element that some Church Fathers, like John of Damascus, spoke of, was that they considered Enoch to be one of the two witnesses mentioned in the Book of Revelation. This view still has many supporters today in Christianity.
