His address to monks, rendered from Coptic, exhorting them to perseverance, and encouraging them against the wiles of Satan.
38 'And it is not fitting to boast at the casting forth of the demons, nor to be uplifted by the healing of diseases: nor is it fitting that he who casts out devils should alone be highly esteemed, while he who casts them not out should be considered nought. But let a man learn the discipline of each one and either imitate, rival, or correct it. For the working of signs is not ours but the Saviour's work: and so He said to His disciples: “Rejoice not that the demons are subject to you, but that your names are written in the heavens.” For the fact that our names are written in heaven is a proof of our virtuous life, but to cast out demons is a favour of the Saviour who granted it. Wherefore to those who boasted in signs but not in virtue, and said: “Lord, in Your name did we not cast out demons, and in Your name did many mighty works?” He answered, “Verily I say unto you, I know you not;” for the Lord knows not the ways of the wicked. But we ought always to pray, as I said above, that we may receive the gift of discerning spirits; that, as it is written, we may not believe every spirit.'
39. 'I should have liked to speak no further and to say nothing from my own promptings, satisfied with what I have said: but lest you should think that I speak at random and believe that I detail these things without experience or truth; for this cause even though I should become as a fool, yet the Lord who hears knows the clearness of my conscience, and that it is not for my own sake, but on account of your affection towards me and at your petition that I again tell what I saw of the practices of evil spirits. How often have they called me blessed and I have cursed them in the name of the Lord! How often have they predicted the rising of the river, and I answered them, “What have you to do with it?” Once they came threatening and surrounded me like soldiers in full armour. At another time they filled the house with horses, wild beasts and creeping things, and I sang: “Some in chariots and some in horses, but we will boast in the name of the Lord our God;” and at the prayers they were turned to flight by the Lord. Once they came in darkness, bearing the appearance of a light, and said, “We have come to give you a light, Antony.” But I closed my eyes and prayed, and immediately the light of the wicked ones was quenched. And a few months after they came as though singing psalms and babbling the words of Scripture, “But I like a deaf man, heard not.” Once they shook the cell with an earthquake, but I continued praying with unshaken heart. And after this they came again making noises, whistling and dancing. But as I prayed and lay singing psalms to myself they immediately began to lament and weep, as if their strength had failed them. But I gave glory to the Lord who had brought down and made an example of their daring and madness.'
40. 'Once a demon exceeding high appeared with pomp, and dared to say, “I am the power of God and I am Providence, what do you wish that I shall give you?” But I then so much the more breathed upon him, and spoke the name of Christ, and set about to smite him. And I seemed to have smitten him, and immediately he, big as he was, together with all his demons, disappeared at the name of Christ. At another time, while I was fasting, he came full of craft, under the semblance of a monk, with what seemed to be loaves, and gave me counsel, saying, “Eat and cease from your many labours. Thou also art a man and art like to fall sick.” But I, perceiving his device, rose up to pray; and he endured it not, for he departed, and through the door there seemed to go out as it were smoke. How often in the desert has he displayed what resembled gold, that I should only touch it and look on it. But I sang psalms against him, and he vanished away. Often they would beat me with stripes, and I repeated again and again, “Nothing shall separate me from the love of Christ,” and at this they rather fell to beating one another. Nor was it I that stayed them and destroyed their power, but it was the Lord, who said, “I beheld Satan as lightning fall from Heaven;” but I, children, mindful of the Apostle's words, transferred this to myself, that you might learn not to faint in discipline, nor to fear the devil nor the delusions of the demons.'
41. 'And since I have become a fool in detailing these things, receive this also as an aid to your safety and fearlessness; and believe me for I do not lie. Once some one knocked at the door of my cell, and going forth I saw one who seemed of great size and tall. Then when I enquired, “Who are you?” he said, “I am Satan.” Then when I said, “Why are you here?” he answered, “Why do the monks and all other Christians blame me undeservedly? Why do they curse me hourly?” Then I answered, “Wherefore do you trouble them?” He said, “I am not he who troubles them, but they trouble themselves, for I have become weak. Have they not read,” “The swords of the enemy have come to an end, and you have destroyed the cities?” “I have no longer a place, a weapon, a city. The Christians are spread everywhere, and at length even the desert is filled with monks. Let them take heed to themselves, and let them not curse me undeservedly.” Then I marvelled at the grace of the Lord, and said to him: “You who art ever a liar and never speakest the truth, this at length, even against your will, you have truly spoken. For the coming of Christ has made you weak, and He has cast you down and stripped you.” But he having heard the Saviour's name, and not being able to bear the burning from it, vanished.'
42. 'If, therefore, the devil himself confesses that his power is gone, we ought utterly to despise both him and his demons; and since the enemy with his hounds has but devices of this sort, we, having got to know their weakness, are able to despise them. Wherefore let us not despond after this fashion, nor let us have a thought of cowardice in our heart, nor frame fears for ourselves, saying, I am afraid lest a demon should come and overthrow me; lest he should lift me up and cast me down; or lest rising against me on a sudden he confound me. Such thoughts let us not have in mind at all, nor let us be sorrowful as though we were perishing; but rather let us be courageous and rejoice always, believing that we are safe. Let us consider in our soul that the Lord is with us, who put the evil spirits to flight and broke their power. Let us consider and lay to heart that while the Lord is with us, our foes can do us no hurt. For when they come they approach us in a form corresponding to the state in which they discover us, and adapt their delusions to the condition of mind in which they find us. If, therefore, they find us timid and confused, they immediately beset the place, like robbers, having found it unguarded; and what we of ourselves are thinking, they do, and more also. For if they find us faint-hearted and cowardly, they mightily increase our terror, by their delusions and threats; and with these the unhappy soul is thenceforth tormented. But if they see us rejoicing in the Lord, contemplating the bliss of the future, mindful of the Lord, deeming all things in His hand, and that no evil spirit has any strength against the Christian, nor any power at all over any one— when they behold the soul fortified with these thoughts— they are discomfited and turned backwards. Thus the enemy, seeing Job fenced round with them, withdrew from him; but finding Judas unguarded, him he took captive. Thus if we are wishful to despise the enemy, let us ever ponder over the things of the Lord, and let the soul ever rejoice in hope. And we shall see the snares of the demon are like smoke, and the evil ones themselves flee rather than pursue. For they are, as I said before, exceeding fearful, ever looking forward to the fire prepared for them.'
