Excerpt from Great Vespers:
Litiya
In Tone 1
It is fitting that the Queen of heaven and earth,* who is more precious than the Cherubim,* and incomparably more glorious than the Seraphim,* be conceived and remain immaculate as the angels,* so that they who are servants of the Lord* can boast of their own Queen, the Mother of God.* Glory and praise to the Lord who willed it so,* the Creator of all things.
It is fitting that the unique and chosen woman* be conceived without sin,* and the power of Satan is now taken away;* for the Mother of God will never bow before him.* Glory and praise to the Lord who willed it so,* the Creator of all things.
It is fitting that the Second Eve* be created and remain without sin* in the manner of the Second Adam;* for the rebirth of mankind now takes place,* just as the fall came through the first Adam and the first Eve.* Christ has renewed all through his new birth,* and it was Mary that gave birth to Him.* Glory and praise to the Lord who willed it so,* the Creator of all things.
Glory… Now…
Before the nativity of the Son of God,* it was fitting for the Father* to bestow the most pure conception upon the Mother of God,* who is betrothed of the Holy Spirit,* that she might be filled with heavenly gifts* in a manner beyond all other creatures.* Glory and praise to the Lord who willed it so,* the Creator of all things.
