“After that,” says John, “he must be loosed a little season.” If the binding and shutting up of the devil means his being made unable to seduce the Church, must his loosing be the recovery of this ability? By no means. For the Church predestined and elected before the foundation of the world, the Church of which it is said, “The Lord knoweth them that are His,” shall never be seduced by him. And yet there shall be a Church in this world even when the devil shall be loosed, as there has been since the beginning, and shall be always, the places of the dying being filled by new believers. For a little after John says that the devil, being loosed, shall draw the nations whom he has seduced in the whole world to make war against the Church, and that the number of these enemies shall be as the sand of the sea. “And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven and devoured them. And the devil who seduced them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.” This relates to the last judgment, but I have thought fit to mention it now, lest any one might suppose that in that short time during which the devil shall be loose there shall be no Church upon earth, whether because the devil finds no Church, or destroys it by manifold persecutions. The devil, then, is not bound during the whole time which this book embraces,–that is, from the first coming of Christ to the end of the world, when He shall come the second time,–not bound in this sense, that during this interval, which goes by the name of a thousand years, he shall not seduce the Church, for not even when loosed shall he seduce it. For certainly if his being bound means that he is not able or not permitted to seduce the Church, what can the loosing of him mean but his being able or permitted to do so? But God forbid that such should be the case! But the binding of the devil is his being prevented from the exercise of his whole power to seduce men, either by violently forcing or fraudulently deceiving them into taking part with him. If he were during so long a period permitted to assail the weakness of men, very many persons, such as God would not wish to expose to such temptation, would have their faith overthrown, or would be prevented from believing; and that this might not happen, he is bound.
But when the short time comes he shall be loosed. For he shall rage with the whole force of himself and his angels for three years and six months; and those with whom he makes war shall have power to withstand all his violence and stratagems. And if he were never loosed, his malicious power would be
less patent, and less proof would be given of the steadfast fortitude of the holy city: it would, in short, be less manifest what good use the Almighty makes of his great evil. For the Almighty does not absolutely seclude the saints from his temptation, but shelters only their inner man, where faith resides, that by outward temptation they may grow in grace. And He binds him that he may not, in the free and eager exercise of his malice, hinder or destroy the faith of those countless weak persons, already believing or yet to believe, from whom the Church must be increased and completed; and he will in the end loose him, that the city of God may see how mighty an adversary it has conquered, to the great glory of its Redeemer, Helper, Deliverer. And what are we in comparison with those believers and saints who shall then exist, seeing that they shall be tested by the loosing of an enemy with whom we make war at the greatest peril even when he is bound? Although it is also certain that even in this intervening period there have been and are some soldiers of Christ so wise and strong, that if they were to be alive in this mortal condition at the time of his loosing, they would both most wisely guard against, and most patiently endure, all his snares and assaults.
