Virgin Mary in the context of "Assumption of Mary"

The Eastern Orthodox Church, officially the Orthodox Catholic Church, and also called the Greek Orthodox Church or simply the Orthodox Church, is one of the three major doctrinal and jurisdictional groups of Christianity. As of 2012, it has approximately 300 million adherents and is the third largest religious community in the world after Catholics and Sunni Muslims. The Eastern Orthodox Church operates as a communion of autocephalous churches, each governed by its bishops via local synods. The church has no central doctrinal or governmental authority analogous to the pope of the Catholic Church. Nevertheless, the Ecumenical Patriarch of Constantinople is recognised by them as primus inter pares ('first among equals'), a title held by the patriarch of Rome prior to 1054. As one of the oldest surviving religious institutions in the world, the Eastern Orthodox Church has played an especially prominent role in the history and culture of Eastern and Southeastern Europe. Since 2018, there has been an ongoing schism between Constantinople and Moscow, with the two not in full communion with each other.

Eastern Orthodox theology is based on the Scriptures and holy tradition, which incorporates the dogmatic decrees of the seven ecumenical councils, and the teaching of the Church Fathers. The church teaches that it is the one, holy, catholic and apostolic church established by Jesus Christ in his Great Commission, and that its bishops are the successors of Christ's apostles. It maintains that it practises the original Christian faith, as passed down by holy tradition. Its patriarchates, descending from the pentarchy, and other autocephalous and autonomous churches, reflect a variety of hierarchical organisation. It recognises seven major sacraments (which are called holy mysteries), of which the Eucharist is the principal one, celebrated liturgically in synaxis. The church teaches that through consecration invoked by a priest, the sacrificial bread and wine become the body and blood of Christ. The Virgin Mary is venerated in the Eastern Orthodox Church as the Theotokos, which means 'God-bearer', and she is honoured in devotions.

In Christian theology, the incarnation is the belief that the pre-existent divine person of Jesus Christ, God the Son, the second person of the Trinity, who is also the Logos (Koine Greek for 'word'), was "made flesh" by being conceived through the power of the Holy Spirit in the womb of a woman, the Virgin Mary, who is also known as the Theotokos (Greek for "God-bearer" or "Mother of God"). The doctrine of the incarnation then entails that Jesus was at the same time both fully God and fully human.

In the incarnation, as traditionally defined by those Churches that adhere to the Council of Chalcedon, the divine nature of the Son was united but not mixed with human nature in one divine person, Jesus, or according to those adhering to the Council of Ephesus, the divine and human natures of Christ are fully united into one composite nature "without mixing, confusion, or separation". This is central to the traditional faith held by most Christians. Alternative views on the subject (see Ebionites and the Gospel of the Hebrews) have been proposed throughout the centuries, but all were rejected by Nicene Christianity.

Intercession or intercessory prayer is the act of praying on behalf of others, or asking a saint in heaven to pray on behalf of oneself or for others.

The Apostle Paul's exhortation to Timothy specified that intercession prayers should be made for all people.

The Council of Ephesus was a council of Christian bishops convened in Ephesus (near present-day Selçuk in Turkey) in AD 431 by the Roman Emperor Theodosius II. This third ecumenical council, an effort to attain consensus in the church through an assembly representing all of Christendom, confirmed the original Nicene Creed, and condemned the teachings of Nestorius, Patriarch of Constantinople, who preferred that the Virgin Mary be called Christotokos, "Christ-bearer" over Theotokos, "God-bearer"; in contrast to Cyril of Alexandria who deemed that Theotokos is enough on its own. It met from 22 June to 31 July 431 at the Church of Mary in Ephesus in Anatolia.

Most Christian denominations believe the Holy Spirit, or Holy Ghost, to be the third divine Person of the Trinity, a triune god manifested as God the Father, God the Son, and God the Holy Spirit, each being God. Nontrinitarian Christians, who reject the doctrine of the Trinity, differ significantly from mainstream Christianity in their beliefs about the Holy Spirit. In Christian theology, pneumatology is the study of the Holy Spirit. Due to Christianity's historical relationship with Judaism, theologians often identify the Holy Spirit with the concept of the Ruach Hakodesh in Jewish scripture, on the theory that Jesus was expanding upon these Jewish concepts. Similar names, and ideas, include the Ruach Elohim (Spirit of God), Ruach YHWH (Spirit of Yahweh), and the Ruach Hakodesh (Holy Spirit). In the New Testament the Holy Spirit is identified with the Spirit of Christ, the Spirit of Truth, and the Paraclete (helper).

The New Testament details a close relationship between the Holy Spirit and Jesus during his earthly life and ministry. The Gospels of Matthew and Luke and the Nicene Creed state that Jesus was "conceived by the Holy Spirit, born of the Virgin Mary". The Holy Spirit descended on Jesus like a dove during his baptism, and in his Farewell Discourse after the Last Supper, Jesus promised to send the Holy Spirit to his disciples after his departure.

Maryam (Arabic: مريم, Maryam; Arabic cognate of 'Mary') is the 19th chapter (sūrah) of the Qur'an with 98 verses (āyāt). The 114 chapters in the Quran are roughly ordered by size. The Quranic chapter is named after Mary, mother of Jesus (ʿIsa, عیسی), and the Virgin Mary in Christian belief. It recounts the events leading up to the birth of Jesus. The text of the surah refers to many known prophetic figures, including Isaac, Jacob, Moses, Aaron, Ishmael, Idris, Adam, Zechariah and Noah.

The Birmingham Quran manuscript preserves the final eight verses (Q19:91–98), on parchment radiocarbon dated to between 568 and 645 CE (56 BH – 25 AH). The Sanaa manuscript, dated between 578 and 669 CE (44 BH – 49 AH), includes verses 2–28.

Our Lady of Kazan, also called Mother of God of Kazan (Russian: Казанская Богоматерь, romanized: Kazanskaya Bogomater'), is a holy icon of the highest stature within the Russian Orthodox Church, representing the Virgin Mary as the protector and patroness of the city of Kazan, and a palladium of all of Russia and Rus', known as the Holy Protectress of Russia. As is the case for any holy entity under a Patriarchate in communion within the greater Eastern Orthodox Church, it is venerated by all Orthodox faithful.

According to legend, the icon was originally acquired from Constantinople, lost in 1438, and miraculously recovered in pristine state over 140 years later in 1579. Two major cathedrals, the Kazan Cathedral, Moscow, and the Kazan Cathedral, St. Petersburg, are consecrated to Our Lady of Kazan, and they display copies of the icon, as do numerous churches throughout the land. The original icon in Kazan was stolen, and probably destroyed, in 1904.
