Sorry I intend to cite the original post but sometimes miss.
The Book of Enoch was considered the authentic writings of the Biblical Enoch in Apostolic times. It was considered Bible to many for a few centuries after. In the Latin and Greek worlds it fell into disrepute as neo-platonic philosophical assumptions came to dominate those churches as they do to this day. (ie. spirit = good, ideal, superior material = base, inferior) The Book of Enoch has always been Scripture in Ethiopia. The Jews of Ethiopia claim to be older than the Church there and when there was a mass immigration of Jews into the Church there the Book of Enoch came with them. As far as anyone can tell the Book of ENoch has always been in Ethiopian Bibles.
I know an Iritrean Evangleical Christian who showed me his protestant Bible printed by the UBS which includes Enoch.
In ancient times Enoch is listed as part of the Bible in Armenian Orthodoxy.
