20. Wherefore having already begun and set out in the way of virtue, let us strive the more that we may attain those things that are before. And let no one turn to the things behind, like Lot's wife, all the more so that the Lord hath said, "No man, having put his hand to the plough, and turning back, is fit for the kingdom of heaven [1026] ." And this turning back is nought else but to feel regret, and to be once more worldly-minded. But fear not to hear of virtue, nor be astonished at the name. For it is not far from us, nor is it without ourselves, but it is within us, and is easy if only we are willing. That they may get knowledge, the Greeks live abroad and cross the sea, but we have no need to depart from home for the sake of the kingdom of heaven, nor to cross the sea for the sake of virtue. For the Lord aforetime hath said, "The kingdom of heaven is within you [1027] ." Wherefore virtue hath need at our hands of willingness alone, since it is in us and is formed from us. For when the soul hath its spiritual faculty in a natural state virtue is formed. And it is in a natural state when it remains as it came into existence. And when it came into existence it was fair and exceeding honest. For this cause Joshua, the son of Nun, in his exhortation said to the people, "Make straight your heart unto the Lord God of Israel [1028] ," and John, "Make your paths straight [1029] ." For rectitude of soul consists in its having its spiritual part in its natural state as created. But on the other hand, when it swerves and turns away from its natural state, that is called vice of the soul. Thus the matter is not difficult. If we abide as we have been made, we are in a state of virtue, but if we think of ignoble things we shall be accounted evil. If, therefore, this thing had to be acquired from without, it would be difficult in reality; but if it is in us, let us keep ourselves from foul thoughts. And as we have received the soul as a deposit, let us preserve it for the Lord, that He may recognise His work as being the same as He made it.
21. And let us strive that wrath rule us not nor lust overcome us, for it is written, "The wrath of man worketh not the righteousness of God. And lust, when it hath conceived, beareth sin, and the sin when it is full grown bringeth forth death [1030] ." Thus living, let us keep guard carefully, and as it is written, "keep our hearts with all watchfulness [1031] ." For we have terrible and crafty foes--the evil spirits--and against them we wrestle, as the Apostle said, "Not against flesh and blood, but against the principalities and against the powers, against the world-rulers of this darkness, against the spiritual hosts of wickedness in the heavenly places [1032] ." Great is their number in the air around us [1033] , and they are not far from us. Now there are great distinctions among them; and concerning their nature and distinctions much could be said, but such a description is for others of greater powers than we possess. But at this time it is pressing and necessary for us only to know their wiles against ourselves.
22. First, therefore, we must know this: that the demons have not been created like what we mean when we call them by that name; for God made nothing evil, but even they have been made good. Having fallen, however, from the heavenly wisdom, since then they have been grovelling on earth. On the one hand they deceived the Greeks with their displays, while out of envy of us Christians they move all things in their desire to hinder us from entry into the heavens; in order that we should not ascend up thither from whence they fell. Thus there is need of much prayer and of discipline, that when a man has received through the Spirit the gift of discerning spirits, he may have power to recognise their characteristics: which of them are less and which more evil; of what nature is the special pursuit of each, and how each of them is overthrown and cast out. For their villainies and the changes in their plots are many. The blessed Apostle and his followers knew such things when they said, "for we are not ignorant of his devices [1034] ;" and we, from the temptations we have suffered at their hands, ought to correct one another under them. Wherefore I, having had proof of them, speak as to children.
23. The demons, therefore, if they see all Christians, and monks especially, labouring cheerfully and advancing, first make an attack by temptation and place hindrances to hamper our way, to wit, evil thoughts. But we need not fear their suggestions, for by prayer, fasting, and faith in the Lord their attack immediately fails. But even when it does they cease not, but knavishly by subtlety come on again. For when they cannot deceive the heart openly with foul pleasures they approach in different guise, and thenceforth shaping displays they attempt to strike fear, changing their shapes, taking the forms of women, wild beasts, creeping things, gigantic bodies, and troops of soldiers. But not even then need ye fear their deceitful displays. For they are nothing and quickly disappear, especially if a man fortify himself beforehand with faith and the sign of the cross [1035] . Yet are they bold and very shameless, for if thus they are worsted they make an onslaught in another manner, and pretend to prophesy and foretell the future, and to shew themselves of a height reaching to the roof and of great breadth; that they may stealthily catch by such displays those who could not be deceived by their arguments. If here also they find the soul strengthened by faith and a hopeful mind, then they bring their leader to their aid.
24. And he said they often appeared as the Lord revealed the devil to Job, saying, "His eyes are as the morning star. From his mouth proceed burning lamps and hearths of fire are cast forth. The smoke of a furnace blazing with the fire of coals proceeds from his nostrils. His breath is coals and from his mouth issues flame [1036] ." When the prince of the demons appears in this wise, the crafty one, as I said before, strikes terror by speaking great things, as again the Lord convicted him saying to Job, for "he counteth iron as straw, and brass as rotten wood, yea he counteth the sea as a pot of ointment, and the depth of the abyss as a captive, and the abyss as a covered walk [1037] ." And by the prophet, "the enemy said, I will pursue and overtake [1038] ," and again by another, "I will grasp the whole world in my hand as a nest, and take it up as eggs that have been left [1039] ." Such, in a word, are their boasts and professions that they may deceive the godly. But not even then ought we, the faithful, to fear his appearance or give heed to his words. For he is a liar and speaketh of truth never a word. And though speaking words so many and so great in his boldness, without doubt, like a dragon he was drawn with a hook by the Saviour [1040] , and as a beast of burden he received the halter round his nostrils, and as a runaway his nostrils were bound with a ring, and his lips bored with an armlet [1041] . And he was bound by the Lord as a sparrow, that we should mock him. And with him are placed the demons his fellows, like serpents and scorpions to be trodden underfoot by us Christians. And the proof of this is that we now live opposed to him. For he who threatened to dry the sea and seize upon the world, behold now cannot stay our discipline, nor even me speaking against him. Let us then heed not his words, for he is a liar: and let us not fear his visions, seeing that they themselves are deceptive. For that which appears in them is no true light, but they are rather the preludes and likenesses of the fire prepared for the demons who attempt to terrify men with those flames in which they themselves will be burned. Doubtless they appear; but in a moment disappear again, hurting none of the faithful, but bringing with them the likeness of that fire which is about to receive themselves. Wherefore it is unfitting that we should fear them on account of these things; for through the grace of Christ all their practices are in vain.
25. Again they are treacherous, and are ready to change themselves into all forms and assume all appearances. Very often also without appearing they imitate the music of harp and voice, and recall the words of Scripture. Sometimes, too, while we are reading they immediately repeat many times, like an echo, what is read. They arouse us from our sleep to prayers; and this constantly, hardly allowing us to sleep at all. At another time they assume the appearance of monks and feign the speech of holy men, that by their similarity they may deceive and thus drag their victims where they will. But no heed must be paid them even if they arouse to prayer, even if they counsel us not to eat at all, even though they seem to accuse and cast shame upon us for those things which once they allowed. For they do this not for the sake of piety or truth, but that they may carry off the simple to despair; and that they may say the discipline is useless, and make men loathe the solitary life as a trouble and burden, and hinder those who in spite of them walk in it.
26. Wherefore the prophet sent by the Lord declared them to be wretched, saying: "Wo is he who giveth his neighbours to drink muddy destruction [1042] ." For such practices and devices are subversive of the way which leads to virtue. And the Lord Himself, even if the demons spoke the truth,--for they said truly "Thou art the Son of God [1043] "--still bridled their mouths and suffered them not to speak; lest haply they should sow their evil along with the truth, and that He might accustom us never to give heed to them even though they appear to speak what is true. For it is unseemly that we, having the holy Scriptures and freedom from the Saviour, should be taught by the devil who hath not kept his own order but hath gone from one mind to another [1044] . Wherefore even when he uses the language of Scripture He forbids him, saying: "But to the sinner said God, Wherefore dost thou declare My ordinances and takest My covenant in thy mouth [1045] ?" For the demons do all things--they prate, they confuse, they dissemble, they confound--to deceive the simple. They din, laugh madly, and whistle; but if no heed is paid to them forthwith they weep and lament as though vanquished.'
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 [1046] ." And again: "But I was as a deaf man and heard not, and as a dumb man who openeth not his mouth, and I became as a man who heareth not [1047] ." 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 [1048] , 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 [1049] ;" 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 forthwith 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 [1050] . 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 forthwith 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 shewing 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 forthwith destroyed a hundred and eighty-five thousand. But demons like these, who have no power, try to terrify at least by their displays [1051] .
