I am not sure what the actual name of the song is, but here are the lyrics:
It is truly right to bless you, O Theotokos, ever blessed and most pure, and the Mother of our God. More honorable than the Cherubim, and more glorious beyond compare than the Seraphim, without stain you gave birth to God the Word. You are truly Theotokos we magnify you.
Theotokos= Mother of God
May God bless all who read my ramblings,
