His address to monks, rendered from Coptic, exhorting them to perseverance, and encouraging them against the wiles of Satan.
27 'The Lord therefore, as God, stayed the mouths of the demons: and it is fitting that we, taught by the saints, should do like them and imitate their courage. For they when they saw these things used to say: “When the sinner rose against me, I was dumb and humble, and kept silence from good words.” And again: “But I was as a deaf man and heard not, and as a dumb man who opens not his mouth, and I became as a man who hears not.” So let us neither hear them as being strangers to us, nor give heed to them even though they arouse us to prayer and speak concerning fasting. But let us rather apply ourselves to our resolve of discipline, and let us not be deceived by them who do all things in deceit, even though they threaten death. For they are weak and can do nought but threaten.
28. 'Already in passing I have spoken on these things, and now I must not shrink from speaking on them at greater length, for to put you in remembrance will be a source of safety. Since the Lord visited earth, the enemy is fallen and his powers weakened. Wherefore although he could do nothing, still like a tyrant, he did not bear his fall quietly, but threatened, though his threats were words only. And let each one of you consider this, and he will be able to despise the demons. Now if they were hampered with such bodies as we are, it would be possible for them to say, “Men when they are hidden we cannot find, but whenever we do find them we do them hurt.” And we also by lying in concealment could escape them, shutting the doors against them. But if they are not of such a nature as this, but are able to enter in, though the doors be shut, and haunt all the air, both they and their leader the devil, and are wishful for evil and ready to injure; and, as the Saviour said, “From the beginning the devil is a manslayer and a father of vice;” while we, though this is so, are alive, and spend our lives all the more in opposing him; it is plain they are powerless. For place is no hindrance to their plots, nor do they look on us as friends that they should spare us; nor are they lovers of good that they should amend. But on the contrary they are evil, and nothing is so much sought after by them as wounding them that love virtue and fear God. But since they have no power to effect anything, they do nought but threaten. But if they could, they would not hesitate, but immediately work evil (for all their desire is set on this), and especially against us. Behold now we are gathered together and speak against them, and they know when we advance they grow weak. If therefore they had power they would permit none of us Christians to live, for godliness is an abomination to a sinner. But since they can do nothing they inflict the greater wounds on themselves; for they can fulfil none of their threats. Next this ought to be considered, that we may be in no fear of them: that if they had the power they would not come in crowds, nor fashion displays, nor with change of form would they frame deceits. But it would suffice that one only should come and accomplish that which he was both able and willing to do: especially as every one who has the power neither slays with display nor strikes fear with tumult, but immediately makes full use of his authority as he wishes. But the demons as they have no power are like actors on the stage changing their shape and frightening children with tumultuous apparition and various forms: from which they ought rather to be despised as showing their weakness. At least the true angel of the Lord sent against the Assyrian had no need for tumults nor displays from without, nor noises nor rattlings, but in quiet he used his power and immediately destroyed a hundred and eighty-five thousand. But demons like these, who have no power, try to terrify at least by their displays.
29. 'But if any one having in mind the history of Job should say, Why then has the devil gone forth and accomplished all things against him; and stripped him of all his possessions, and slew his children, and smote him with evil ulcers? Let such a one, on the other hand, recognise that the devil was not the strong man, but God who delivered Job to him to be tried. Certainly he had no power to do anything, but he asked, and having received it, he has wrought what he did. So also from this the enemy is the more to be condemned, for although willing he could not prevail against one just man. For if he could have, he would not have asked permission. But having asked not once but also a second time, he shows his weakness and want of power. And it is no wonder if he could do nothing against Job, when destruction would not have come even on his cattle had not God allowed it. And he has not the power over swine, for as it is written in the Gospel, they besought the Lord, saying, “Let us enter the swine.” But if they had power not even against swine, much less have they any over men formed in the image of God.
30. 'So then we ought to fear God only, and despise the demons, and be in no fear of them. But the more they do these things the more let us intensify our discipline against them, for a good life and faith in God is a great weapon. At any rate they fear the fasting, the sleeplessness, the prayers, the meekness, the quietness, the contempt of money and vainglory, the humility, the love of the poor, the alms, the freedom from anger of the ascetics, and, chief of all, their piety towards Christ. Wherefore they do all things that they may not have any that trample on them, knowing the grace given to the faithful against them by the Saviour, when He says, “Behold I have given to you power to tread upon serpents and scorpions, and upon all the power of the enemy.”
31. 'Wherefore if they pretend to foretell the future, let no one give heed, for often they announce beforehand that the brethren are coming days after. And they do come. The demons, however, do this not from any care for the hearers, but to gain their trust, and that then at length, having got them in their power, they may destroy them. Whence we must give no heed to them, but ought rather to confute them when speaking, since we do not need them. For what wonder is it, if with more subtle bodies than men have, when they have seen them start on their journey, they surpass them in speed, and announce their coming? Just as a horseman getting a start of a man on foot announces the arrival of the latter beforehand, so in this there is no need for us to wonder at them. For they know none of those things which are not yet in existence; but God only is He who knows all things before their birth. But these, like thieves, running off first with what they see, proclaim it: to how many already have they announced our business— that we are assembled together, and discuss measures against them, before any one of us could go and tell these things. This in good truth a fleet-footed boy could do, getting far ahead of one less swift. But what I mean is this. If any one begins to walk from the Thebaid, or from any other district, before he begins to walk, they do not know whether he will walk. But when they have seen him walking they run on, and before he comes up report his approach. And so it falls out that after a few days the travellers arrive. But often the walkers turn back, and the demons prove false.'
