Step 4:11 — Terrible indeed was the judgment of a good judge and shepherd which I once saw in a monastery. For while I was there, it happened that a robber applied for admission to the monastic life. And that most excellent pastor and physician ordered him to take seven days of complete rest, just to see the kind of life in the place. When the week had passed, the pastor called him and asked him privately: ‘Would you like to live with us?’ And when he saw that he agreed to this with all sincerity, he then asked him what evil he had done in the world. And when he saw that he readily confessed everything, he tried him still further, and said: ‘I want you to tell this in the presence of all the brethren.’ But he really did hate his sin, and, scorning all shame, without the least hesitation he promised to do it. ‘And if you like,’ he said, ‘I will tell it in the middle of the city of Alexandria.’
And so, the shepherd gathered all his sheep in the church, to the number of 230, and during Divine Service (for it was Sunday), after the reading of the Gospel, he introduced this irreproachable convict. He was dragged by several of the brethren, who gave him moderate blows. His hands were tied behind his back, he was dressed in a hair shirt, his head was sprinkled with ashes. All were astonished at the sight. And immediately a woeful cry rang out, for no one knew what was happening. Then, when the robber appeared at the doors of the church,4 that holy superior who had such love for souls, said to him in a loud voice: ‘Stop! You are not worthy to enter here.’
Dumbfounded by the voice of the shepherd coming from the sanctuary (for he thought, as he afterwards assured us with oaths, that he had heard not a human voice, but thunder), he instantly fell on his face, trembling and shaking all over with fear. As he lay on the ground and moistened the floor with his tears, this wonderful physician, using all means for his salvation, and wishing to give to all an example of saving and effectual humility, again exhorted him, in the presence of all, to tell in detail what he had done. And with terror he confessed one after another all his sins, which revolted every ear, not only sins of the flesh, natural and unnatural, with rational beings and with animals, but even poisoning, murder and many other kinds which it is indecent to hear or commit to writing. And when he had finished his confession, the shepherd at once allowed him to be given the habit and numbered among the brethren.
12. Amazed by the wisdom of that holy man, I asked him when we were alone: ‘Why did you make such an extraordinary show?’ That true physician replied: ‘For two reasons: firstly, in order to deliver the penitent himself from future shame by present shame; and it really did that, Brother John. For he did not rise from the floor until he was granted remission of all his sins. And do not doubt this, for one of the brethren who was there confided to me, saying: “I saw someone terrible holding a pen and writing-tablet, and as the prostrate man told each sin, he crossed it out with a pen.” And this is likely, for it says: I said, I will confess against myself my sin to the Lord; and Thou hast forgiven the wickedness of my heart. Secondly, because there are others in the brotherhood who have unconfessed sins, and I want to induce them to confess too, for without this no one will obtain forgiveness.’
4 Orthodox churches are divided into the narthex, the catholicon, and the sanctuary. In ancient times the unbaptized were admitted to the narthex but not to the catholicon. The robber was already in the narthex. He was halted not at the outer door but at the doors of the catholicon.
