Wyatt, also, the one big hymn in St John's liturgy dedicated to the Mother of God is called the theotokion, which comes after the Precious Gifts have been consecrated and the celebrant offers them on behalf of our "forefathers, fathers, prophets, apostles, preachers, evangelists, martyrs, confessors, ascetics, every righteous spirit made perfect in faith and especially for our most holy, pure, most blessed and glorious lady, the Theotokos and ever-virgin Mary".
The theotokion for most weeks is as follows:
"It is truly right to bless thee, o Theotokos,
ever blessed and most pure and the Mother of our God.
More honorable than the cherubim,
and beyond compare more glorious than the seraphim.
Without corruption thou gavest birth to God the Word.
True Theotokos, we magnify thee."
The following is often substituted for the usual theotokion:
"All of Creation rejoices in thee, o full of grace:
the angels in heaven and the race of men,
o sanctified temple and noetic paradise,
the glory of virgins, of whom God was incarnate
and became a child, our God before the ages.
He made thy body into a throne,
and thy womb more spacious than the heavens.
All of creation rejoices in thee, o full of grace:
Glory be to thee."
Again, I feel both of these hymns give the proper "treatment" to the Mother of God (apologies for the crass turn of phrase), both extolling her holiness and supreme virtue and setting these qualities in the context of her being the birth-giver of the Incarnate Word of God, who is the only source of our life and of our salvation.
