I’ve been studying the literature of the second temple period. Particularly items found at Qumran and other literature that are extant but also verified at Qumran. Now the bible refers to a lot of outside sources. The OT refers to the book of wars ect… the NT specifically Jude takes a quote from Enoch 1. Which was a popular type of literature at the time. I find that Clement quotes from Tobit and Judith which are in the LXX. Now from a sola scriptura point of view how does one take certain scripture, like Jude which quotes from Enoch 1 (which we don’t consider cannon) as an outside source of information? Some of Jesus’ statements seem similar to the apocalyptic literature of the day like when he says “there will be floods in diverse places, wars and rumors of wars”. Now that I understand some of the Essenian belief systems I see a heavy influence on the Gospel of John when he speaks of light and dark a motif that the (heretical?) letter of Barnabas also includes. Also I wonder that John the Baptist audience might not have been Essenes as well. Though both Jesus and John separated themselves from the sectarian influence. Though Christianity in it’s own way kind of mimics certain sectarian statements that the Essenses had. It’s obvious that the earliest fathers took this literature seriously in their writings. So how are Christians who are primarily sola scriptura view scripture relating to non cannon books as being factual? Especially since we now that the book of Enoch was probably written between 400 and 200 BC and is fictional speculation?
