Our righteous Father Sergius was born in Rostov, north of Moscow, about the year 1314. Named Bartholomew in Baptism, he was brought up in Radonezh, and at the death of his parents he withdrew to the wilderness to become a monk. It is notable that without having been trained in a monastery, he was of such a spiritual stature as to be able to take up the perilous eremitical life from the beginning, without falling into delusion or despondency. When he had endured with courage the deprivations of the solitary life, other monks began to come to him, for whom he was made abbot against his will. On the counsel of Philotheus, Patriarch of Constantinople, he organized his monks according to the cenobitic life, appointing duties to each. While Anthony and Theodosius of Kiev, and the other righteous Fathers before Sergius, had established their monasteries near to cities, Sergius was the leader and light of those who went far into the wilderness, and after his example the untrodden forests of northern Russia were settled with monks. When Grand Duke Demetrius Donskoy was about to go to battle against the invading Tartars, he first sought the blessing of Saint Sergius, through whose prayers he was triumphant. Saint Sergius was adorned with the highest virtues of Christ-like humility and burning love for God and neighbour, and received the gift of working wonders, of casting out demons, and of discretion for leading souls to salvation. When he served the Divine Liturgy, an Angel served with him visibly; he was also vouchsafed the visitation of the most holy Theotokos with the Apostles Peter and John. He was gathered to his Fathers on September 25, 1392. At the recovery of his holy relics on July 5, 1422, his body and garments were found fragrant and incorrupt. His life was written by the monks of Epiphanius, who knew him.

Saint Athanasius had Trebizond for his homeland. He first entered the monastic life on the mountain called Kymaeos or Kyminas, which is in Mysia of Bithynia, then he went to Mount Athos and founded a large monastery, which is known as the Great Lavra. He became so renowned for his virtue that from Rome, Calabria, Georgia, and elsewhere, rulers, men of wealth and nobility, abbots, and even bishops came to him and were subject to him. When the time for his departure was at hand, God revealed to him how it would take place, so that he was able to instruct his spiritual children not to be troubled when it should come to pass. A new church was being built for the sake of the many who came to him, and only the dome had not been finished. Together with six of the brethren, the Saint went to the top of the church to help the workmen. The dome collapsed, and they fell. Five were killed at once, and the Saint died three hours later. His holy body remained incorrupt and he worked many miracles after his death. He reposed about the end of the tenth century.

This Saint, great and renowned among the ascetics of Egypt, lived in the fourth century in Scete of Nitria. After the death of Saint Anthony the Great, he left Scete to live in Saint Anthony's cave; he said of this, "Thus in the cave of a lion, a fox makes his dwelling." When Sisoës was at the end of his long life of labours, as the Fathers were gathered about him, his face began to shine, and he said, "Behold, Abba Anthony is come"; then, "Behold, the choir of the Prophets is come"; his face shone yet more bright, and he said, "Behold, the choir of the Apostles is come." The light of his countenance increased, and he seemed to be talking with someone. The Fathers asked him of this; in his humility, he said he was asking the Angels for time to repent. Finally his face became as bright as the sun, so that the Fathers were filled with fear. He said, "Behold, the Lord is come, and He says, 'Bring Me the vessel of the desert,'" and as he gave up his soul into the hands of God, there was as it were a flash of lightning, and the whole dwelling was filled with a sweet fragrance.

The holy Martyr Procopius was born of a pious father named Christopher, but his mother Theodosia was an idolater. After Christopher's death, she presented Neanias - for this was the Saint's name before - to Diocletian, who was at Antioch in Syria. Diocletian made him Duke of Alexandria, and sent him there to punish the Christians. On the way to Alexandria, our Lord spoke to Neanias as once He had to Saul, and turned this new persecutor to faith in Him. Neanias turned back to Scythopolis, and preached Christ. He was betrayed by his own mother, and was arrested and tormented in Caesarea of Palestine. While he was in prison, the Lord appeared to him again and gave him the new name of Procopius (which is derived from the Greek word meaning "progress, advancement"). He was brought out of prison and taken to worship the idols, but at his prayer, the idols fell; many then believed in Christ and suffered martyrdom, among them certain soldiers, twelve women of senatorial rank, and the Saint's own mother, Theodosia. Saint Procopius, after further torments and imprisonment, was beheaded about the year 290.

In 451, during the reign of the Sovereigns Marcian and Pulcheria, the Fourth Ecumenical Council was convoked in Chalcedon against Eutyches and those of like mind with him. After much debate, the Fathers who were the defenders of Orthodoxy, being 630 in number, agreed among themselves and with those who were of contrary mind, to write their respective definitions of faith in separate books, and to ask God to confirm the truth in this matter. When they had prepared these texts, they placed the two tomes in the case that held Saint Euphemia's relics, sealed it, and departed. After three days of night-long supplications, they opened the reliquary in the presence of the Emperor, and found the tome of the heretics under the feet of the Martyr, and that of the Orthodox in her right hand. (For her life, see Sept. 16.)
