Marian hymns are Christian songs focused on Mary, mother of Jesus. They are used in both devotional and liturgical services, particularly by the Roman Catholic, Eastern Orthodox, Oriental Orthodox, Anglican, and Lutheran churches. They are often used in the month of May devotions. Some have also been adopted as Christmas hymns. Marian hymns are not popular among some Protestants, as they see Marian veneration as idolatry. However, the practice is very common among Christians of Catholic traditions, and a key component of the Eastern Orthodox liturgy. There are many more hymns to Mary within the Eastern Orthodox yearly cycle of liturgy than in Roman Catholic liturgy. The Magnificat hymn (song of the Virgin Mary) is one of the eight most ancient Christian hymns and historian Marjorie Reeves states that it is perhaps the earliest Christian hymn. The Magnificat is named after the opening line in the 4th century Vulgate Bible, based on , and continues to be widely used to date by Roman Catholics, Anglicans and the Eastern Orthodox. Marian hymns are at times shared among different groups of Christians, or are influenced by other hymns. For instance, The second stanza of the Anglican hymn Ye Watchers and Ye Holy Ones is derived from the Eastern Orthodox hymn to the Theotokos. Marian hymns may be analyzed to shed light on the Mariological approach within a given historical period, e.g. the Akathist to the Theotokos has been the subject of detailed study related to the Marian themes it presents within its various components. Eastern Church In the Eastern Church, the Theotokia (i.e. hymns to the Theotokos) are an essential part of the Divine Liturgy. The positioning of Marian hymns in the Orthodox liturgical services effectively places the Theotokos in the most prominent place after Christ, in that the Theotokia immediately follow the hymns that praise Christ. In the Theotokia people repeat the name Mary many times as a sign of their close friendship with her, and as an expression of the desire to call her by her name. Parts of the Axion Estin hymn date back to 8th-century (Cosmas of Maiuma). In the Eastern Church, the Theotokia often include biblical references that emphasize the mystery of the Incarnation. These Marian hymns have been used in daily prayers since early Christianity (they became part of liturgy later) as a way to teach people the Orthodox beliefs, and to prepare them against ideas
