Elements of Sectarian Judaism appear to consider 1 Enoch to be sacred. This is partly indicated by the presence of 1 Enoch in Aramaic at Qumran, along with the fact that many Second Temple Period books drew on 1 Enoch's content. Materials found among the Dead Sea Scrolls attest to the influence of Enochic tradition. Loren T. Struckenbruck "The Book of Enoch: Its Reception in Second Temple Jewish and Christian Tradition, Early Christianity 4 (2013); 7-40 (esp. p.11).
At Qumran, the Book of Jubilees, related peshers of Book of Jubilees, Genesis Apocryphon, a pesher on the Story of the Watchers and the Damascus Document directly quote from the Book of Enoch. The term pesher means interpretation. Peshers are essentially commentaries on the texts. Peshers for all books in the Old Testament exist at Qumran. The fact that the Book of the Watchers from 1 Enoch had an official pesher indicates that 1 Enoch was likely considered scripture.
The Enochic tradition is critical to understand the Second Temple notions of the origin of demons being the disembodied spirits of giants. This is evidenced by the early Christian attitudes towards spirits as impure. This is completely absent from Greco-Roman literate up through the second century C.E. Clinton Wahlen, Jesus and the Impurity of Spirits in the Synoptic Gospels (Wissenschaftliche Untersuchungen zum Neuen Testament 2. Reihe 185 (Tubingen: Mohr Siebeck, 2004), 1, 66-67, 170.
This is why relying on the Church Fathers will not give you a full picture and context of the New Testament. You must read the New Testament and Old Testament in the context they were written.
