And Enoch walked with God: and he was not; for God took him. Genesis 5:24

By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God. Hebrews 11:5

Let us not give loose reins to our soul, that it should have power to run with sinners and the wicked, lest we become like them. The final stumbling-block (or source of danger) approaches, concerning which it is written, as Enoch says, "For this end the Lord has cut short the times and the days, that His Beloved may hasten; and He will come to the inheritance." And the prophet also speaks thus: "Ten kingdoms shall reign upon the earth, and a little king shall rise up after them, who shall subdue under one three of the kings." In like manner Daniel says concerning the same, "And I beheld the fourth beast, wicked and powerful, and more savage than all the beasts of the earth, and how from it sprang up ten horns, and out of them a little budding horn, and how it subdued under one three of the great horns." Barnabas (A.D. 70-130) ch.4

Let us take (for instance) Enoch, who, being found righteous in obedience, was translated, and death was never known to happen to him. Clement of Rome (A.D. 96) ch.9

Enoch, too, pleasing God, without circumcision, discharged the office of God's legate to the angels although he was a man, and was translated, and is preserved until now as a witness of the just judgment of God, because the angels when they had transgressed fell to the earth for judgment, but the man who pleased [God] was translated for salvation. Irenaeus (A.D. 180) Ante-Nicene Fathers vol.1 pg.481

Enoch had preceded, predicting that "the demons, and the spirits of the angelic apostates, would turn into idolatry all the elements, all the garniture of the universe, all things contained in the heaven, in the sea, in the earth, that they might be consecrated as God, in opposition to God." All things, therefore, does human error worship, except the Founder of all Himself. Tertullian (A.D. 198) Ante-Nicene Fathers vol.3 pg. 62-63

Enoch no doubt was translated, and so was Elijah; nor did they experience death: it was postponed, (and only postponed,) most certainly: they are reserved for the suffering of death, that by their blood they may extinguish Antichrist. Tertullian (A.D. 198) Ante-Nicene Fathers vol.3 pg. 227

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. Noah therefore, no doubt, might have succeeded in the trusteeship of (his) preaching; or, had the case been otherwise, he would not have been silent alike concerning the disposition (of things) made by God, his Preserver, and concerning the particular glory of his own house. Tertullian (A.D. 198) Ante-Nicene Fathers vol.4 pg.15

But since Enoch in the same Scripture has preached likewise concerning the Lord, nothing at all must be rejected by us which pertains to us; and we read that "every Scripture suitable for edification is divinely inspired." By the Jews it may now seem to have been rejected for that (very) reason, just like all the other (portions) nearly which tell of Christ. Nor, of course, is this fact wonderful, that they did not receive some Scriptures which spoke of Him whom even in person, speaking in their presence, they were not to receive. To these considerations is added the fact that Enoch possesses a testimony in the Apostle Jude. Tertullian (A.D. 198) Ante-Nicene Fathers vol.4 pg.16
