1 Enoch 1:9 — the very text Jude cites
Behold, he comes with ten thousand holy ones to execute judgment.
If ‘the faith once delivered’ meant ‘nothing outside the later Protestant table of contents,’ Jude sabotaged himself by quoting a book Protestants do not print. He is fencing the gospel of the Lord who comes to judge — not shrink-wrapping a canon that did not yet exist.
