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.)

Saint Olga, renowned for her wisdom and sobriety, in her youth became the wife of Igor, Great Prince of Kiev, who ruled during the tenth century. After her husband's death, she herself ruled capably, and was finally moved to accept the Faith of Christ. She traveled to Constantinople to receive Holy Baptism. The Emperor, seeing her outward beauty and inward greatness, asked her to marry him. She said she could not do this before she was baptized; she furthermore asked him to be her Godfather at the font, which he agreed to do. After she was baptized (receiving the name of Helen), the Emperor repeated his proposal of marriage. She answered that now he was her father, through holy Baptism, and that not even among the heathen was it heard of a man marrying his daughter. Gracefully accepting to be outwitted by her, he sent her back to her land with priests and sacred texts and holy icons. Although her son Svyatoslav remained a pagan, she planted the seed of faith in her grandson Vladimir (see July 15). She reposed in peace in 969.
