WE believe that one of the holy Trinity, the Son and Word of God the Father, emptied himself and took the form of a servant [Phil 2:7], manifested in our form.
For this is what the Theologian says, the Word became flesh [John 1:14], and the great Apostle writes, God was manifested in the flesh [1 Tim 3:16].
And he is one and the same in two natures, perfect God and perfect man; and in each perfection he left nothing that is proper to them both unassumed, but rather, as genuinely a son he possessed as God everything which pertains to the Father, as human everything which pertains to his Mother.
And so, just as he is uncircumscribed like his Father, so like his Mother he is circumscribed, that is to say formed in the image in the likeness of his Mother.
St Theodore the Studite, Letters, Bk II 156: To the brethren with his son Patrikios. Translation by Archimandrite Ephrem Lash.
ONCE again the godlike day of the Master’s festival is here; for he who is seated in the highest has now clearly visited us through his honoured Image; he who is unseen by the Cherubim above appears through painting to those to whom he has become like, formed ineffably by the immaculate finger of the Father according to his likeness.
As we worship it with faith and love we are sanctified.
OUR Saviour, the Dayspring from the east, has visited us from on high; and we who were in darkness and shadow, have now found the truth; for the Lord is born of a Virgin. (Three times)
Be glad, you just, heavens rejoice, mountains leap for joy; Christ is born and the Virgin sits like the Cherubim throne carrying in her bosom God the Word made flesh.
Shepherds glorify the one that is born; Magi offer gifts to the Master; Angels sing praises, saying: Lord beyond understanding, glory to you!
Matins for the Feast of the Nativity (Dec 25).
SEIZED with dread they accompanied your inviolate body that had contained God; while they went on before in a manner not of this world and crying out, unseen, to the ranks above them: See, the Queen of all, God’s Child, has come.
Lift up the gates, and in a manner not of this world receive the Mother of the everlasting light.
For through her the salvation of all mortals has come.
We have not the strength to gaze on her, and it is not possible to render her worthy honour.
For her excellence outstrips all understanding.
I SING the praise of your mercy without measure, O my Maker, for you emptied yourself to take on and to save the nature of mortals that had grown evil.
And though God, you accepted to be born in my likeness from the pure Child of God and to descend as far as Hell, as you wished me to be saved at the prayers of her who bore you, O Master full of pity.
