On the Sunday that falls from the 13th to the 19th of the present month, we chant the Service to the 630 Holy and God-bearing Fathers who came together for the 4th Ecumenical Council who assembled in Chalcedon in 451, to condemn Eutyches, who taught that there was only one nature, the divine, in Christ after the Incarnation, and Dioscorus, Patriarch of Alexandria, who illegally received Eutyches back into communion and deposed Saint Flavian, Patriarch of Constantinople, who had excommunicated Eutyches.

In the Slavic tradition, on this Sunday, the Fathers of the first six Ecumenical Councils are all commemorated.

This Martyr lived during the reign of Claudius II (268-270). She was from Pisidia of Cilicia and was the only daughter of a certain priest of the idols. On being orphaned by her mother, she was handed over to a certain woman who instructed her in the Faith of Christ. When she was fifteen years old, she was apprehended by the ruler of Olmbrius, and when asked her name, homeland, and faith, she answered: "My name is Marina; I am the offspring of the Pisidia; I call upon the Name of my Lord Jesus Christ." Because of this she endured bonds, imprisonment, and many whippings, and was finally beheaded in the year 270. Saint Marina is especially invoked for deliverance from demonic possession.

Elias of great fame was from Thisbe or Thesbe, a town of Galaad (Gilead), beyond the Jordan. He was of priestly lineage, a man of a solitary and ascetical character, clothed in a mantle of sheep skin, and girded about his loins with a leathern belt. His name is interpreted as "Yah is my God." His zeal for the glory of God was compared to fire, and his speech for teaching and rebuke was likened unto a burning lamp. From this too he received the name Zealot. Therefore, set aflame with such zeal, he sternly reproved the impiety and lawlessness of Ahab and his wife Jezebel. He shut up heaven by means of prayer, and it did not rain for three years and six months. Ravens brought him food for his need when, at God's command, he was hiding by the torrent of Horrath. He multiplied the little flour and oil of the poor widow of Sarephtha of Sidon, who had given him hospitality in her home, and when her son died, he raised him up. He brought down fire from Heaven upon Mount Carmel, and it burned up the sacrifice offered to God before all the people of Israel, that they might know the truth. At the torrent of Kisson, he slew 450 false prophets and priests who worshipped idols and led the people astray. He received food wondrously at the hand of an Angel, and being strengthened by this food he walked for forty days and forty nights. He beheld God on Mount Horeb, as far as this is possible for human nature. He foretold the destruction of the house of Ahab, and the death of his son Ohozias; and as for the two captains of fifty that were sent by the king, he burned them for their punishment, bringing fire down from Heaven. He divided the flow of the Jordan, and he and his disciple Elisseus passed through as it were on dry land; and finally, while speaking with him, Elias was suddenly snatched away by a fiery chariot in the year 895 B.C., and he ascended as though into heaven, whither God most certainly translated him alive, as He did Enoch (Gen. 5:24; IV Kings 2: 11). But from thence also, after seven years, by means of an epistle he reproached Joram, the son of Josaphat, as it is written: "And there came a message in writing to him from Elias the Prophet, saying, Thus saith the Lord God of David thy father, Because thou hast not walked in the way," and so forth (II Chron. 21:12). According to the opinion of the majority of the interpreters, this came to pass either through his disciple Elisseus, or through another Prophet when Elias appeared to them, even as he appeared on Mount Tabor to the disciples of Christ (see Aug. 6).

Saint Maria Skobtsova of Paris lived a life devoted to serving the poor and the marginalized. She was born Elizaveta Pilenko in 1891 in Riga, Latvia to devout Russian Orthodox parents. Her father died when she was fourteen, and her grief led her to atheism. As a young teenager she became involved in the socialist and intellectual circles in St. Petersburg. By eighteen she was a published poet and married to a Bolshevik. Her desire to actively serve the needy - more than simply discuss social change - led her back to a faith in Christ. She then became the first woman accepted to study at the Theological Academy of the Alexander Nevsky Monastery in St. Petersburg.

After the Bolshevik Revolution, she was elected Mayor of Anapa but had to flee Russia for Paris in 1923. Elizaveta was inspired to devote her life completely to serving the poor after her daughter, Nastia, died of meningitis in 1926. After her second marriage ended in 1932, Metropolitan Evlogii of Paris tonsured her a nun with the name Maria and blessed her to live a "monasticism in the world" devoted to social service.

Initially devoted to the Russian emigres in Paris, she founded a sanatorium along with homes to serve single mothers, families, and single men. By 1937, 120 dinners were served each day. Much of the work she did herself: begging for food, cooking the soup, and even embroidering the icons for their chapel.

By 1942, Maria's work turned to assisting the Jewish population. She helped Father Dimitri Klepinin issue fake baptismal certificates for Jews that came to their aide. In a mass arrest in July of that year, 12,884 Jews were taken to a sports stadium before being transferred to Auschwitz. Maria spent three days visiting the prisoners, bringing them food, and even rescuing some of the children by smuggling them out in trash cans. She also aided Jews in escaping to Southern France which was unoccupied by the Nazis.

Maria was arrested in February, 1943, and was sent to Ravensbruck concentration camp in Germany. For two years, she raised the spirits of her fellow prisoners, helping them remember their human dignity. She led discussion groups on literature, history, and theology, despite her weakening health. On March 31, 1945, a short time before the camp was rescued, Saint Maria was taken to the gas chambers; some prisoners say she took the place of a fellow Jewish prisoner.

On January 18th, 2004, the Holy Synod of the Ecumenical Patriarchate recognized Mother Maria Skobtsova as a saint along with her three fellow workers who also died in German concentration camps: her son Yuri, Fr. Dimitri Klepinin, and Ilya Fondaminsky. They are all commemorated in the Orthodox Church on July 20th.
