The Book of Enoch is an ancient Jewish religious work, ascribed by tradition to Enoch, the great-grandfather of Noah, which played a crucial role in forming the worldview of the authors of the New Testament.
The Bible, as we hold it today, is esteemed by many religious institutions and especially Conservative Christians to be the inspired, inerrant Word of God. This doctrinal position affirms that the Bible is unlike all other books or collections of works in that it is free of error due to having been given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be perfect, thoroughly furnished unto all good works (2 Tim. 3:16, 17). While no other text can claim this same unique authority, the Book of Enoch is an ancient Jewish religious work, ascribed by tradition to Enoch, the great-grandfather of Noah, which played a crucial role in forming the worldview of the authors of the New Testament, who were not only familiar with it but quoted it in the New Testament, Epistle of Jude, Jude 1:14 15, and is attributed there to “Enoch the Seventh from Adam” (1 En 60:8). The text was also utilized by the community that originally collected and studied the Dead Sea Scrolls. While some churches today include Enoch as part of the biblical canon (for example the Ethiopian Orthodox Tewahedo Church and Eritrean Orthodox Tewahedo Church), other Christian denominations and scholars accept it only as having historical or theological non-canonical interest and frequently use or assigned it as supplemental materials within academic settings to help students and scholars discover or better understand cultural and historical context of the early Christian Church. The Book of Enoch provides commentators valuable insight into what many ancient Jews and early Christians believed when, God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets (Heb. 1:1).
As Dr. Michael S. Heiser in the Introduction to his important book Reversing Hermon so powerfully notes:
The Book of Enoch is therefore intended to be an important supplemental resource for assisting serious researchers and students in the study of the Bible.
