From the liturgy of St. John Chrysostom:

“O only-begotten Son and Word of God,
immortal being,
you who accepted for our salvation
to become incarnate of the holy Mother of God
and ever-virgin Mary,
you who without change became man
and were crucified,
O Christ our God,
you who by your death have crushed death,
you who are one of the Holy Trinity,
glorified with the Father and the Holy Spirit,
save us!”
