I've seen at least four or five different renderings of this prayer to the Theotokos, which one do you prefer?
Jordanville Prayer Book (1979) - "It is truly meet and right to bless thee, the Ever-Blessed and Most Pure Virgin and Mother of our God. More honourable than the Cherubim, and incomparably more glorious than the Seraphim, thou who in virginity didst bear God the Word, thee, true Mother of God, we magnify."
Jordanville Prayer Book (1996) - "It is truly meet to bless thee, the Theotokos, ever-blessed and most blameless, and Mother of our God. More honourable than the Cherubim, and beyond compare more glorious than the Seraphim, who without corruption gavest birth to God the Word, the very Theotokos, thee do we magnify."
Antiochian Prayer Book - "It is truly meet to bless thee, O Theotokos, who are ever blessed and all-blameless, and the Mother of our God. More honorable than the Cherubim, and more glorious beyond compare than the Seraphim, thou who without stain barest God the Word, and art truly Theotokos: we magnify thee."
OCA Orthodox Prayer Book - "Meet it is in truth, to glorify Thee, O Birthgiver of God, ever blessed and all-undefiled, the Mother of our God. More honourable than the Cherubim, and beyond compare more glorious than the Seraphim, Thou who without stain didst bear God the word, True Birth-giver of God, we magnify Thee."
