In October, there are no Twelve Feasts, but this month one great Feast of the Theotokos is remembered. Also in the church calendar there are days in bold in honor of the celebration of the memory of the revered saints and icons of the Mother of God.
On the first day of October, the Church remembers the miraculous image of the Most Holy Theotokos the Healer. The icon is so named because it depicts the Virgin Mary healing a sick person. Before this image, they pray to the Mother of God in various diseases. The holy image is in Moscow in the Alekseevsky convent.
On October 9, the Orthodox Church commemorates the memory of St. John the Theologian and St. Tikhon, Patriarch of Moscow. The Holy Apostle John departed to the Lord that day. The saint is known for being one of the closest disciples of Christ. John is called the Church Evangelist, as he wrote the Holy Gospel. Saint Tikhon is one of the Russian saints of the early 20th century. He was the patriarch of all Russia. The saint is known for his outstanding pastoral care for his flock and his great love for people.
On October 14, the entire fullness of the Russian Orthodox Church celebrates the celebrations dedicated to the Mother of God. This day is called the Protection of the Mother of God. The holiday is named in honor of an event that took place in Constantinople in the 10th century. The Mother of God appeared to Saint Righteous Andrew under the arches of the Blakherna Church. She spread her veil over the believers. Hence the name of the celebration. This day is especially honored in Russia.
