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, Apocryphal and Pseudepigraphal literature such as contained in the Book of Enoch, provides material that often precedes or follows the chronology of biblical texts, which frequently are used or assigned as supplemental works within academic settings to help students and scholars discover or better understand cultural and historical context within the Word of God. Whether or not the information contained in the apocryphal literature is entirely precise—as is the canon of Scripture—these ancient texts provide 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).

The first part of the Book of Enoch describes the fall of the Watchers, the angels who fathered the Nephilim. The remainder of the book describes Enoch's visits to heaven in the form of travels, visions and dreams, and his revelations.
