Despite its unknown origins, Christians once accepted the words of this Book of Enoch as authentic scripture, especially the part about the fallen angels and their prophesied judgment. In fact, many of the key concepts used by Jesus Christ himself seem directly connected to terms and ideas in the Book of Enoch. Thus, it is hard to avoid the conclusion that Jesus had not only studied the book, but also respected it highly enough to adopt and elaborate on its specific descriptions of the coming kingdom and its theme of inevitable judgment descending upon "the wicked" - the term most often used in the Old Testament to describe the Watchers.
