Just a short hymn from the Eastern Church in honor of this day.   

          Kontakion (Tone 3)

Today the Virgin Theotokos Mary

The bridal chamber of the Heavenly Bridegroom

By the will of God is born of a barren woman,

Being prepared as the chariot of God the Word.

She was fore-ordained for this, since she is the divine gate and the true Mother of Life.
