I quickly recognize Enoch as being connected to the understanding of the world and history of the people of Jesus time. We see this in the quotation of it, the presence of portions of the text we have today in the dead see scrolls, and even in scripture where the covering of the head of the woman is against the attention of the angels described as going in and taking human women as wives in Genesis (this also in accord with Jubilees).
It provides context, but it can also be hard for us to account for. Particularly as it speaks of treasuries of snow and windows through which wind blows, we are led to ask how much is poetry and imagination and how much is revelation. Certainly it speaks of things we have no basis for understanding. Some say it describes in one place Enoch being shown a black hole, where there is terrible chaos and fire with mountains snared, and columns of fire rising and descending beyond sight, and a terrible void. Or do we imagine we understand what we read?
As we read it should we say we are led astray without it? It doesn't seem so. It seems to echo what we can already discern from scripture. It does tend to magnify and expand what we have read already, but is it all truth particularly where it speaks beyond the other scriptures we have? We are in a poor position to judge, and in such a position we are probably wise to defer to the Septuagint which embodied the scripture that would have been recognized at the time of Jesus, and the books of the new testament which proclaim and clarify the gospel.
It's an interesting book which like Jubilees helps us understand what the people of that time thought and understood. It doesn't appear to take away from Christ and indeed seems to afirm his coming, but I would still read or quote with careful regard to footing, seeing that we judge it in context of the more sure ground of the word already passed to us.
