Chapter VII.
Of an illusion into which another fell for lack of discretion.
Why also should I speak of one (whose name we had rather not mention as he is still alive), who for a long while received a devil in the brightness of an angelic form, and was often deceived by countless revelations from him and believed that he was a messenger of righteousness: for when these were granted, every night he provided a light in his cell without the need of any lamp. At last he was ordered by the devil to offer up to God his own son who was living with him in the monastery, in order that his merits might by this sacrifice be made equal to those of the patriarch Abraham. And he was so far seduced by his persuasion that he would really have committed the murder unless his son had seen him getting ready the knife and sharpening it with unusual care, and looking for the chains with which he meant to tie him up for the sacrifice when he was going to offer him up; and had fled away in terror with a presentiment of the coming crime.
Chapter VIII.
Of the fall and deception of a monk of Mesopotamia.
It is a long business too to tell the story of the deception of that monk of Mesopotamia, who observed an abstinence that could be imitated by but few in that country, which he had practised for many years concealed in his cell, and at last was so deceived by revelations and dreams that came from the devil that after so many labours and good deeds, in which he had surpassed all those who dwelt in the same parts, he actually relapsed miserably into Judaism and circumcision of the flesh. For when the devil by accustoming him to visions through the wish to entice him to believe a falsehood in the end, had like a messenger of truth revealed to him for a long while what was perfectly true, at length he showed him Christian folk together with the leaders of our religion and creed; viz. Apostles and Martyrs, in darkness and filth, and foul and disfigured with all squalor, and on the other hand the Jewish people with Moses, the patriarchs and prophets, dancing with all joy and shining with dazzling light; and so persuaded him that if he wanted to share their reward and bliss, he must at once submit to circumcision. And so none of these would have been so miserably deceived, if they had endeavoured to obtain a power of discretion. Thus the mischances and trials of many show how dangerous it is to be without the grace of discretion.
Chapter IX.
A question about the acquirement of true discretion.
To this Germanus: It has been fully and completely shown both by recent instances and by the decisions of the ancients how discretion is in some sense the fountain head and the root of all virtues. We want then to learn how it ought to be gained, or how we can tell whether it is genuine and from God, or whether it is spurious and from the devil: so that (to use the figure of that gospel parable which you discussed on a former occasion, in which we are bidden to become good money changers [1180] ) we may be able to see the figure of the true king stamped on the coin and to detect what is not stamped on coin that is current, and that, as you said in yesterday's talk using an ordinary expression, we may reject it as counterfeit, under the teaching of that skill which you treated of with sufficient fulness and detail, and showed ought to belong to the man who is spiritually a good money changer of the gospel. For of what good will it be to have recognized the value of that virtue and grace if we do not know how to seek for it and to gain it?

Chapter X.
The answer how true discretion may be gained.
Then Moses: True discretion, said he, is only secured by true humility. And of this humility the first proof is given by reserving everything (not only what you do but also what you think), for the scrutiny of the elders, so as not to trust at all in your own judgment but to acquiesce in their decisions in all points, and to acknowledge what ought to be considered good or bad by their traditions. [1181] And this habit will not only teach a young man to walk in the right path through the true way of discretion, but will also keep him unhurt by all the crafts and deceits of the enemy. For a man cannot possibly be deceived, who lives not by his own judgment but according to the example of the elders, nor will our crafty foe be able to abuse the ignorance of one who is not accustomed from false modesty to conceal all the thoughts which rise in his heart, but either checks them or suffers them to remain, in accordance with the ripened judgment of the elders. For a wrong thought is enfeebled at the moment that it is discovered: and even before the sentence of discretion has been given, the foul serpent is by the power of confession dragged out, so to speak, from his dark under-ground cavern, and in some sense shown up and sent away in disgrace. For evil thoughts will hold sway in us just so long as they are hidden in the heart: and that you may gather still more effectually the power of this judgment I will tell you what Abbot Serapion did, [1182] and what he used often to tell to the younger brethren for their edification.
