Another day, Theodore (of Tabennesi) went off to a monastery...

…to visit the brothers, and straightway they brought him a brother they accused of having stolen something, that he should expel him from among the brothers for this reason. The culprit, however, was not this brother, but another who passed for a faithful man among all the brothers. But they were accusing the former because he was somewhat negligent in their view.

When the thief realized that he had not only committed the first fault but that, moreover, because of him they were going to drive the other brother away from the monastery, he went to see Theodore privately and said to him, “Forgive me, my father; I am the one who committed the theft.” Theodore said to him, “The Lord has forgiven you the fault you have committed, for clearing the innocent in our presence.”

Then he called the one who had been falsely accused and said to him, “I know that you are not the perpetrator of this fault. But even if the brothers afflicted you a little for the fault you have not committed, nevertheless do not be proud of your innocence in this case. For you are doubtless indebted to the Lord for other faults you have committed. Therefore, give Him thanks and be in fear of Him all you life long.” Then he said to the brothers about this matter, “Have you not entrusted me with judgment so that I might pass sentence? Well, it is God’s will that he should be absolved. Indeed, we are all in need of God’s mercy.”

In the Holy Trinity hut of St. Anne's Skete (on Mt. Athos)...

…there lived, many years ago, five natural brothers. Because of Satan’s envy, they started quarrelling among themselves in such a way that they became known as troublemakers. They did ask forgiveness of each other every night, however, and thus they were forgiven.

Many years were passed in this way. Then one day no noise was heard coming from their hut. That night the dikaios of the skete was informed in his sleep that all five brothers had reposed in the Lord. He went with some other fathers to the hut, and indeed they saw that it was true. All five of them had departed to the Lord in a position of prostration, while asking forgiveness of each other. The forgiving and merciful God had taken them away right after Vespers.

Thus God gave a sign of justification and salvation, a proof of correction and forbearance, and a sign that one should never judge his fellow men.

Father Ilarion of the holy monastery of Simonopetra...

…whose obedience it was to nurse the sick, never went to sleep if any of the fathers were ill. He was entirely self-sacrificing in his care of his patients. Using his prayer rope, he prayed all night long, pacing up and down saying, “Lord, have mercy on your servant,” and “Holy Unmercenary Physicians, intercede for this servant of God.” He also went fishing for his patients, after which he would cook his catch for them in an attempt to help them become stronger and feel better.

Antioch had another patriarch...

…who was compassionate and merciful. His name was Alexander. One of his secretaries once stole some gold from him, fled in fear and came to the Thebaid in Egypt. He was found wandering around by the bloodthirsty barbarians of Egypt and of the Thebaid; they took him as a slave to the remotest corner of their land. When the godly Alexander heard about this, he ransomed him from captivity at a cost of eighty five pieces of gold. When the captive returned, the bishop was so loving and gentle with him that one of the inhabitants of the city once said, “There is nothing more profitable or advantageous than to sin against Alexander.” On another occasion, one of the deacons slandered Alexander before all the clergy. But the godly Alexander prostrated himself before the man saying, “Brother, forgive me.”
