And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.
All Commentaries on Revelation 20:1 Go To Revelation 20
Victorinus of Pettau
AD 303
Those years wherein Satan is bound are in the first advent of Christ, even to the end of the age; and they are called a thousand, according to that mode of speaking, wherein a part is signified by the whole, just as is that passage, the word which He commanded for a thousand generations, although they are not a thousand. Moreover that he says, and he cast him into the abyss, he says this, because the devil, excluded from the hearts of believers, began to take possession of the wicked, in whose hearts, blinded day by day, he is shut up as if in a profound abyss. And he shut him up, says he, and put a seal upon him, that he should not deceive the nations until the thousand years should be finished. He shut the door upon him, it is said, that is, he forbade and restrained his seducing those who belong to Christ. Moreover, he put a seal upon him, because it is hidden who belong to the side of the devil, and who to that of Christ. For we know not of those who seem to stand whether they shall not fall, and of those who are down it is uncertain whether they may rise. Moreover, that he says that he is bound and shut up, that he may not seduce the nations, the nations signify the Church, seeing that of them it itself is formed, and which being seduced, he previously held until, he says, the thousand years should be completed, that is, what is left of the sixth day, to wit, of the sixth age, which subsists for a thousand years; after this he must be loosed for a little season. The little season signifies three years and six months, in which with all his power the devil will avenge himself under Antichrist against the Church. Finally, he says, after that the devil shall be loosed, and will seduce the nations in the whole world, and will entice war against the Church, the number of whose foes shall be as the sand of the sea.
