The Orthodox church calendar can be called differently as saints. This naming is not accidental, because the days of the memory of various saints are celebrated every day in the Church.
The Orthodox church calendar for November 13 does not contain twelve or other great Orthodox holidays. However, on this day, the Church honors the memory of several saints, not only common Christian, but also Russian.
On November 13, the memory of the apostles from the seventy is celebrated: Stachia, Amplia, Urvan, Narkissa, Apellius and Aristobulus. From the New Testament history it is known that after the election of the twelve apostles Christ chose seventy more people who also worked hard in preaching the Christian faith. Many of the seventy apostles were bishops. The Apostle Stachy was made bishop by Saint Andrew the First-Called. Archpastoral service took place in Byzantium for 16 years. There he died his own death. Saints Urvan and Amplius were also bishops (in Macedonia and Diaspole). These apostles were martyred for the preaching of Christianity from the Jews and the pagan Hellenes. Saint Narkissus was bishopric in Athens, and Saint Apellius in Heraclius of Thrace. The Holy Apostle Aristobulus was the brother of the Apostle Barnabas. The Holy Chief Apostle Paul made Aristobulus the bishop of Ancient Britain, where the latter suffered a martyr's death for Christ.
On November 13, the martyr Epimachus is remembered in the Church. This saint was originally from Egypt. At a young age he went into the desert for an ascetic life. When Epimachus learned about the persecution of Christians in Alexandria, he hastened there to encourage the believers, since there were also those who renounced the faith. Saint Epimachus confirmed many in Christianity. For his confession, he himself was imprisoned, and then, after various tortures, he underwent a beheading with a sword. This happened around the year 250.
Another saint, whose memory is celebrated on November 13th, is the Monk Mavra. This ascetic of piety lived in Constantinople in the 5th century, where she founded a monastic monastery.
Among the Russian saints whose memory is celebrated on November 13, it is worth mentioning the Monks Spiridon and Nikodim of the Caves. They lived in the XII century and were priests of the famous Kiev-Pechersk Lavra. The obedience of the prosphores passed. Known for their exploits of fasting and prayer. The relics of these saints rest in the Kiev caves at the Lavra.
In 2000, at the jubilee Council of Bishops of the Russian Church under the representation of His Holiness Patriarch Alexy II, it was decided to include in the Russian calendar the names of thousands of people who suffered for the faith of Christ during the years of Soviet power. Such saints are called New Martyrs and Confessors of Russia. Almost every day of the calendar is marked with the names of the holy martyrs, monastic martyrs and other saints. On November 13, the following new Russian martyrs are remembered: Hieromartyrs John Kochurov, Vsevolod Smirnov, Alexander Vozdvizhensky, Sergiy Rozanov, Alexy Sibirskiy, Vasily Arkhangelsky, Peter Voskoboinikov, Vasily Kolokolov; as well as the Monk Martyrs: Leonid Molchanov and Innokenty Mazurin.
