Theotokos (/ˌθiəˈtɒkəs/; Greek: Θεοτόκος, transliterated Theotókos) is the Greek title of Mary, the mother of Jesus used especially in the Eastern Orthodox, Oriental Orthodox, and Eastern Catholic Churches. Its literal English translations include God-bearer and the one who gives birth to God. Less literal translations include Mother of God. Roman Catholics and Anglicans use the title Mother of God more often than Theotokos. The Council of Ephesus decreed in 431 that Mary is Theotokos because her son Jesus is one person who is both God and man, divine and human.

Theotokos is a compound of two Greek words, Θεός God and τόκος parturition, childbirth. Literally, this translates as God-bearer or the one who gives birth to God; historian Jaroslav Pelikan translated it more precisely as "the one who gives birth to the one who is God". However, since many English-speaking Orthodox find this literal translation awkward, in liturgical use, Theotokos is often left untranslated, or paraphrased as Mother of God. The latter title is the literal translation of a distinct title in Greek, Μήτηρ του Θεού (translit. Mētēr tou Theou). Mother of God also accurately translates the Greek words Θεομήτωρ (translit. Theomētor; also spelled Θεομήτηρ, translit. Theomētēr) and Μητρόθεος (translit. Mētrotheos), which are found in patristic and liturgical texts, e.g.

Sir John Kenneth Tavener (born 28 January 1944) is a British composer, best known for such religious, minimal works as "The Whale", and "Funeral Ikos". He began as a prodigy; in 1968, at the age of 24, he was described by the Guardian as "the musical discovery of the year", while The Times said he was "among the very best creative talents of his generation." During his career he has become one of the best known and regarded composers of his generation. Tavener was knighted in 2000 for his services to music and has won an Ivor Novello Award.

John Kenneth Tavener was born on 28 January 1944 in Wembley, London, England, and claims to be a direct descendant of the 16th-century composer John Taverner. He was educated at Highgate School (where a fellow pupil was John Rutter) and at the Royal Academy of Music, where his tutors included Sir Lennox Berkeley. He first came to prominence in 1968 with his dramatic cantata The Whale, based on the Old Testament story of Jonah. It was premièred at the London Sinfonietta's début concert and later recorded by Apple Records. The following year he began teaching at Trinity College of Music, London. Other works released by Apple included his Celtic Requiem. In 1977, he joined the Russian Orthodox Church. Orthodox theology and Orthodox liturgical traditions became a major influence on his work. He was particularly drawn to its mysticism, studying and setting to music the writings of Church Fathers and competing a setting of the Liturgy of St John Chrysostom, the principal eucharistic liturgy of the Orthodox Church.

Patty Griffin, born Patricia Jean Griffin, March 16, 1964, is an American Grammy award-winning singer-songwriter and musician. She is especially known for her down-home crafting of songs and her connection to musicians including Emmylou Harris, Ellis Paul, Rory Block and the Dixie Chicks, who have played with her onstage as well as performing cover songs of Griffin's work, exposing many of her compositions to mainstream pop and country music audiences outside Griffin's folk music circle of fans. She was also recipient of the Americana Music Association's highest honor as "Artist of the Year" in 2007, as well as taking home the award for best album for Children Running Through. In 2011, Griffin won a Grammy Award for Best Traditional Gospel Album for Downtown Church.

Patty Griffin is from Old Town, Maine, United States, next to the Penobscot Native American reservation. She is primarily a guitarist, pianist, and vocalist, with a distinctive voice. The youngest child in her family with six older siblings, she bought a guitar for $50 at age 16, and sang and played, but had no inclination at the time to become a professional musician. After a short marriage which ended in 1992, Griffin began playing in Boston coffee houses, and was scouted by A&M Records, who signed Griffin on the strength of her demo tape; however A&M thought it to be overproduced, so Nile Rodgers and A&M instead released a stripped-down reworking of her demo tape, as an album called Living with Ghosts.

Arvo Pärt (born 11 September 1935; Estonian pronunciation: [ˈɑrvo ˈpært]) is an Estonian classical composer and one of the most prominent living composers of sacred music. Since the late 1970s, Pärt has worked in a minimalist style that employs his self-invented compositional technique, tintinnabuli. His music also takes inspiration from Gregorian chant.

Pärt was born in Paide, Järva County, Estonia. A prolonged struggle with Soviet officials led him to emigrate with his wife and their two sons in 1980. He lived first in Vienna, where he took Austrian citizenship, and then re-located to Berlin. He returned to Estonia around the turn of the 21st century and now lives alternately in Berlin and in Tallinn.

Familiar works by Pärt are Cantus In Memoriam Benjamin Britten for string orchestra and bell (1977) and the string quintet "Fratres I" (1977, revised 1983), which he transcribed for string orchestra and percussion, the solo violin "Fratres II" and the cello ensemble "Fratres III" (both 1980).
