Genesis 5:29

I am aware that the Scripture of Enoch, which has assigned this order (of action) to angels, is not received by some, because it is not admitted into the Jewish canon either. I suppose they did not think that, having been published before the deluge, it could have safely survived that world-wide calamity, the abolisher of all things. If that is the reason (for rejecting it), let them recall to their memory that Noah, the survivor of the deluge, was the great-grandson of Enoch himself; and he, of course, had heard and remembered, from domestic renown and hereditary tradition, concerning his own great-grandfather’s “grace in the sight of God,” and concerning all his preachings; since Enoch had given no other charge to Methuselah than that he should hand on the knowledge of them to his posterity. …

And this is the cause why the fig-tree may be said not to have obtained the kingdom over trees, which, in a spiritual sense, mean men; and the fig-tree the command, because man desired, even after the fall, again to be subject to the dominion of virtue, and not to be deprived of the immortality of the paradise of pleasure. But, having transgressed, he was rejected and cast far away, as one who could no longer be governed by immortality, nor was capable of receiving it. And the first message to him after the transgression was preached by Noah, to which, if he had applied his mind, he might have been saved from sin; for in it he promised both happiness and rest from evils, if he gave heed to it with all his might, just as the vine promises to yield wine to those who cultivate it with care and labour. …

Serenus : You have propounded two not unimportant questions, to which I will reply, to the best of my ability, in the order in which you have raised them. We cannot possibly believe that spiritual existences can have carnal intercourse with women. But if this could ever have literally happened how is it that it does not now also sometimes take place, and that we do not see some in the same way born of women by the agency of demons without intercourse with men? especially when it is clear that they delight in the pollution of lust, which they would certainly prefer to bring about through their own agency rather than through that of men, if they could possibly manage it, as Ecclesiastes declares: “What is it that hath been? The same that is. And what is it that hath been done? The same that is done. …

The soul of just men perceive in the Son a Medicine of life; and so it felt desires that He might come in its own days, and then would it taste His sweetness. Enoch was longing for Him, and since on earth the Son he saw not, he was justified by great faith, and mounted up in Heaven to see Him. Who is there that will spurn at grace, when the Gift that they of old gained not by much labour, freely comes to men now? For Him Lamech also looked who might come and lovingly give Him quiet from his labour and the toiling of his hands, and from the earth the Just One had cursed. Lamech then beheld his son, Noah, him, in whom were figured types relating to the Son. In the stead of the Lord afar off, the type at hand afforded quiet. Yea Noah also longed to see Him, the taste of whose assisting graces he had tasted. …
