In my study of the book of Jude, the study guide that I was using to help me in this had a notation concerning verses 14-15. The study guide's author had a note on those verses to the effect that Jude 14-15 was, in reality, pretty much a word-for-word quotation from what the study guide's author said was a "pseudepigraphical" book entitled 1 Enoch. I had never heard of this claim before to the effect that, God the Holy Spirit moved upon the Apostle Jude to cite some ancient text when Jude penned his warning concerning the ever increasing number of, apparently, demon-influenced false prophets/teachers that would show up even as early as the first century A. D. Now, I'm not sure that my study guide's author made that claim to cast some doubt in the minds of his readers that, therefore, the canonicity of Jude should be questioned or not. OTOH, I do know that the Apostle Paul made reference and/or cited some pagan Greek poets in his Mars Hill defense in Acts 17, so maybe this reference to "Enoch" is something similar to that. Since I've had zero seminary training experience, I have no idea what pseudepigrapha/pseudepigraphical means. I've heard of the term apocrypha, but apparently 1 Enoch (which would seem to infer that, therefore, there must also be at least a book entitled 2 Enoch, and possibly more "Enoch's.") Could some of my BB friends out there enlighten me as to exactly what is meant by the term pseudepigrapha and/or a pseudepigraphical book? How is, say, 1 Enoch different in genre than, e.g., 1 Macabbees? Are there any currently available books you can recommend that you consider to be a reliable introduction to both of these extra-Biblical writings so that I might be a little better informed about these kinds of writings that are "out there floating around in the dark, murky shadows of the ancient past"?
