The significance of the Incarnation has been extensively discussed throughout Christian history, and is the subject of countless hymns and prayers. For instance, the Divine Liturgy of St. John Chrysostom (c. 400), as used by Eastern Orthodox Christians and Byzantine Catholics, includes this “Hymn to the Only Begotten Son”:
O only begotten Son and Word of God,Who, being immortal,
[Deigned] for our salvation
To become incarnate
Of the holy Theotokos and ever-virgin Mary,
And became man without change;
You were also crucified
O Christ our God,
And by death have trampled Death,
Being one of the Holy Trinity,
Glorified with the Father and the Holy Spirit—Save us!"
