^The notation Old Style or (OS) is sometimes used to indicate a date in the Julian Calendar (which is used by churches on the "Old Calendar"). The notation New Style or (NS), indicates a date in the Revised Julian calendar (which is used by churches on the "New Calendar").
^A great Christian ruler, Monomakh’s Crown or “Cap” epitomized the ruling tradition of Kievan Rus' and was later captured and taken to Moscow where it was used to crown the dukes of Muscovy, who were later known as “tsars.” He taught his children to pray the Jesus Prayer as it was the “very best of prayers as it invokes the Name of Christ.” The time of his rule is regarded as Kyiv’s Golden Age. He was enshrined, together with St Yaroslav the Wise, in St Sophia’s Cathedral in Kyiv.[13]
^Also: Sophia (Chotokourídou née Saoulidi) of Kleisoura, or Sophia the Righteous. Saint Sophia lived as an ascetic in an abandoned monastery in Kleisoura, Western Macedonia, Greece. She died on May 6th, 1974. On October 4, 2011, she was canonized by the Ecumenical Patriarchate.[19]
^According to the Old CalendaristOrthodox Church of Greece (Holy Synod in Resistance), "the holy Eldress received the Great and Angelic Schema in October of 1971 — her name being changed from Sophia to the Nun Myrtidiotissa — from the hand of Archimandrite Father Cyprian (later the Old Calendarist Metropolitan of Óropos and Phylé), Abbot of the Holy Monastery of Sts. Cyprian and Justina in Phyle, Áttica (Athens), Greece. Serving as her sponsor was the now reposed nun, Eldress Maria Myrtidiotissa, Foundress and Abbess of the Holy Convent of the Annunciation of the Theotókos, in Oinoússes, on the island of Chíos."[22] According to John Sanidopoulos (M.T.S, Th.M), administrator of the weblog Mystagogy, "from the time when the Ecclesiastical Calendar changed in Greece, Sophia would keep the fasts of both the Old and New Calendar so as not to be an offense to anyone. Unfortunately there is a tendency among Old Calendarists to distort facts and consider her one of their own, but this does not conform to reality as she was always in communion with the Church."
^Saint Sophia of Kleisoura's repose occurred on the date of May 6th. Therefore, Orthodox Churches on the Old Calendar celebrate her feast day together with the Saints of April 23rd, which are commemorated by them on the calendar day of May 6th, thus observing her feast day on April 23rd.
^"Theophylact Lopatinsky was of Volhynian extraction; he studied and received the tonsure at Kieff, was prefect of the Spiritual Academy at Moscow from 1706 to 1708, and then rector of the same academy till 1722, when he became Archimandrite of the Choudoff, and a member (counsellor) of the newly instituted synod. In 1723 he was ordained Bishop of Tver and Kashinsk, and in March 1725 was raised to the rank of Archbishop; and became the second of the two vice-presidents of the synod, (Theophanes Procopovich being the first). In 1728 he published a book against "The Lutheran and Calvinistic Heresies," in defense of the "Rock of Faith" of Stephen Yavorsky, which as well as that work gave great offense to the Duke Biron, and subjected its author to various persecutions, and to imprisonment as a common lay person for five years, till the death of the Empress Anne and the fall of Biron, which took place in 1740, when he was set at liberty, and publicly reinstated by the synod in full assembly, but died of paralysis before he could resume the charge of his diocese. He left behind him another work in MS. under the following title: "A Rejoinder to the Answer of Franciscus Buddeus, addressed to a friend living at Moscow, on the Lutheran heresy, against the book of the late Most Reverend Metropolitan of Riazan entitled the Rock of Faith."
