St. John Cassian: On the Acquisition of True 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) 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. 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, and what he used often to tell to the younger brethren for their edification.
