Although Jude may have had access
to the Book of Enoch, the more important question is: where did the
author of the Book of Enoch obtain the information concerning what Enoch
said? With respect to biblical inspiration and the plenary truth of Scripture,
Jude would have had access to the same original statement of Enoch as the Book
of Enoch itself obtained. (See above footnote concerning the original
source for the account concerning the “body of Moses”). As it stands, Jude was
inspired by the Holy Spirit to write the words of Enoch from an unknown ancient
source, and the Book of Enoch just happens to overlap with Jude on this
issue, but this does not make the Book of Enoch—considering it contains
many myths and legends itself—as the primary source for Jude, especially since
Jude quotes from Enoch himself, not from a book purporting to contain Enoch’s words.
