O Monogenes Yios

''Only-Begotten Son'' ( grc, Ὁ Μονογενὴς Υἱὸς, Church Slavonic: Единородный Сыне, Ukrainian: Єдинородний Сине, Old Armenian: Միածին Վորդի), sometimes called "Justinian's Hymn", the "Anthem of Orthodoxy" and/or the "Hymn of the Incarnation", was composed around the 4th or 5th centuries. This hymn is chanted at the end of the Second Antiphon during the Divine Liturgies of St John Chrysostom, St Basil the Great and of St Gregory the Illuminator (Armenian Divine Liturgy), and at the Little Entrance during the Liturgy of Saint James.

Attribution to St. Athanasius

This hymn is sometimes ascribed to Pope Athanasius I of Alexandria. It was written after the First Ecumenical Council at Nicea as an affirmation of the Christological Formula set down by Athanasius. According to this hypothesis, the hymn was first used in the Church of Alexandria but was distributed by Athanasius to all the churches of the world. It is still currently used as a mournful hymn during the service of Great Friday in the Coptic Orthodox Church of Alexandria, with its length exceeding 10 minutes due to its long and deep melismatic nature. It is also chanted in the introductory portion of the Divine Liturgy of the Eastern Orthodox Church and those Eastern Catholic Churches which observe the Byzantine Rite. The hymn is a theological statement of faith in the dogma of the Incarnation.

Alternative Attributions

There are traditions attributing the hymn to Emperor Justinian and Severus of Antioch. It is popularly believed that Justinian is the person responsible for the hymn's spread and popularity. During the controversy caused by the Origenists, Emperor Justinian declared that this hymn should be sung in all Christian Churches. Due to this tradition, the hymn is sometimes referred to as "Justinian's Hymn".

The Oriental Orthodox tradition however, ascribes the hymn to Severus of Antioch, and it is referred to in Syriac Orthodox liturgical books as the “Hymn of St. Severus.” In the Syriac Orthodox liturgy, the hymn is sung at the start of the Divine Liturgy, whereas in the Armenian Orthodox liturgy, it is sung during the second antiphon, and in the Coptic Orthodox liturgy, during Holy Week.

Text

Only-Begotten Son and Immortal Word of God,
Who for our salvation didst will to be incarnate of the holy Theotokos and Ever-Virgin Mary;
Who without change didst become man and was crucified;
Who art one of the Holy Trinity, glorified with the Father and the Holy Spirit:
O Christ our God, trampling down death by death, save us! Variant text as sung in some Eastern Churches in the United States.

Theology

The key word, ''Monogenēs'', is drawn from the Gospel of John , , and 3:16. The first of these verses describes the pre-incarnate Logos as being " only-begotten of the Father"; the second speaks of Jesus' earthly ministry; and the third describes the offering of the Incarnate Christ for the salvation of those who believe. The term ''Monogenes'' is also found in the Nicene Creed as established by the First Ecumenical Council in 325 AD.
