Hebrews 2:1 Therefore we must give the more earnest heed to the things we have heard, lest we drift away.
The writer arrests our attention with the adverb, therefore. Because of these things, he says, give the more earnest heed to what we have been taught. The typical date given for Hebrews having been written seems to hover around 68 A.D., two years before the destruction of the temple at the hands of the Roman general Titus. Angels, while playing a large role in the Old Testament, could become an inappropriate object of fascination, as is demonstrated in the Book of Enoch, an Apocryphal text, typically excluded from Protestant Bibles. More than this, however, one must consider the advent of Gnostic teaching and its emphasis on angels, including ones Gnostics term aeons.
