Jude (brother of Jesus) and Peter (inner circle of Jesus) would hardly have used the Book of Enoch for reference if Jesus had not believed it to be scripture. The gospels tell how Jesus opened the scriptures to them, especially scriptures concerning Himself, so the closest disciples knew which books Jesus regarded as important scriptures. The fact Peter and Jude drew attention to the Book of Enoch reflects the importance Jesus placed on it and sanction He gave it.
