Abba Moses said: "It is a good thing, as I said, not to hide your thoughts from the fathers. But you should not tell them to just anyone; you should confess them to spiritual masters who have discrimination, not simply to those whose hair has grown white with age. Many who have looked to age as a guide, and then revealed their thoughts, have not only remained unhealed but have been driven to despair because of the inexperience of those to whom they confessed.

There was one a very zealous brother who was greatly troubled by the demon of unchastity. He went to a certain father and confessed his private thoughts to him; but this father, being inexperienced, became angry when he heard about them and told the brother that he was contemptible and unworthy of the monastic habit for having entertained thoughts such as these. When the brother heard this, he lost heart, left his cell and set off back to the world.
Through God's providence, however, Abba Apollos, one of the most experienced of the elders, chanced to meet him and, seeing him over-wrought and very despondent, asked him why he was in this state. At first the brother did not reply because he was so depressed but, after the elder had pleaded with him, he told him what was wrong, saying: "Because I was often troubled by evil thoughts, I went to tell them to the elder; and as he said I have no hope of salvation, I have given up and am now on my way back to the world."

Seeing what had happened, Abba Apollos confronted him, and asked him where he was going and why he was so deeply troubled. Although he realized that the holy man knew what was wrong with him, he was too ashamed to say anything. Abba Apollos then said to him: "Return to your cell, and the future recognize your own weakness. The devil has either not noticed or has despised you, and so not thought you worth fighting. Not there has been any question of a fight: you could not stand up to his provocation even for a day! This has happened to you because, when you received a younger brother who was attacked by our common enemy, you drove him to despair instead of preparing him for the battle.
You did not recall the wise precept: "Deliver them that are being led away to death; and redeem them that are appointed to be slain" (Prov. 24:11 LXX). You did not even remember the parable of our Savior, which teaches us not to break a bruised reed or quench a smoking flax (cf. Matt. 12:20). None of us could endure the plots of the enemy, or allay the fiery turmoil of our nature, if God's grace did not protect our human weakness. Seeing, then, that God has had this compassion for us, let us pray to Him together and ask Him to withdraw the whip with which he has lashed you. "For He wounds but binds up; He strikes but His hands heal" (Job 5:18) "The Lord kills and gives life; he brings down to the grave and raises again. . . . He brings low and lifts up" (I Sam. 2:6-7). After Abba Apollos had said this and he had prayed, the attack which had been launched against the elder was at once suspended. Finally, Abba Apollos advised him to ask God to give him "tongue of the learned" so as to know "how to speak a word in season" (Is. 50:4).
