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.

Tsar Nicholas II was the son of Alexander III, who had reposed in the arms of Saint John of Kronstadt. Having been raised in piety, Tsar Nicholas ever sought to rule in a spirit consonant with the precepts of Orthodoxy and the best traditions of his nation. Tsaritsa Alexandra, a grand-daughter of Queen Victoria of England, and a convert from Lutheranism, was noted for her piety and compassion for the poor and suffering. Their five children were beloved of all for their kindness, modesty, and guilelessness.

Amidst the political turmoil of 1917, Tsar Nicholas selflessly abdicated the throne for what he believed was the good of his country. Although he had abdicated willingly, the revolutionaries put him and his family under house arrest, then sent them under guard to Tobolsk and finally Ekaterinburg. A letter written from Tobolsk by Grand Duchess Olga, the eldest of the children, shows their nobility of soul. She writes, "My father asks that I convey to all those who have remained devoted to him ... that they should not take vengeance on his account, because he has forgiven everyone and prays for them all. Nor should they avenge themselves. Rather, they should bear in mind that this evil which is now present in the world will become yet stronger, but that evil will not conquer evil, but only love shall do so."

After enduring sixteen months of imprisonment, deprivation, and humiliation with a Christian patience which moved even their captors, they and those who were with them gained their crowns of martyrdom when they were shot and stabbed to death in the cellar of the Ipatiev house in Ekaterinburg in 1918.

Together with them are also commemorated those who faithfully served them, and were either slain with them, or on their account: General Elias Tatishchev; Prince Basil Dolgorukov; the physician Eugene Dotkin; the lady-in-waiting Countess Anastasia Hendrikova; the serving-maid Anna Demidova; the cook John Kharitonov; and the sailors Clement Nagorny and John Sednev.
