The Book of Enoch differs from the canonical Bible in several key ways:
1. It is not considered divinely inspired scripture by most Christian and Jewish traditions. Only the Ethiopian Orthodox Church includes it in their biblical canon[1].
2. Much of its content is apocalyptic and esoteric, focusing on topics like fallen angels, cosmic secrets, and end times prophecies that go beyond what is found in canonical scripture[1][3].
3. It was written later than most Old Testament books, likely between 300-100 BC, and was not included in the Hebrew Bible or Septuagint[1].
4. While a small portion is quoted in the New Testament book of Jude, the vast majority of its content is not referenced elsewhere in the Bible[1][3].
5. It contains some ideas that seem to contradict accepted biblical theology, like attributing the origin of evil spirits to the Nephilim[4].
6. Its textual history and transmission is less reliable than canonical books, with far fewer early manuscripts available[3].
7. It did not meet the criteria used by early church leaders to determine canonicity, such as apostolic authorship and widespread acceptance[3].
While some find it interesting for historical context, most Christian traditions do not consider it authoritative scripture on par with the canonical Bible.
