Incense Prayers in Sacramentary of Ratoldus

 Two prayers used by the priest from 9th century Sacramentary of Ratoldus, for incense at the Offertory:

I. O Lord Our God, we earnestly pray with suppliant devotion that just as Thou hast received the gifts of Abel, Noah, Aaron, Zacharias, and Samuel, and all Thy Saints, so mayest Thou deign to receive this incense from our sinful hand unto an odor of sweetness, and the remission of all our sins.

II. O Lord, with this fragrance and incense, may Thy wrath be assuaged against me, this place, and this people, and do Thou mercifully grant that we may be the smoke of good fragrance to Thee for the taking hold of eternal life.

Leavened Bread in a Preface of the Old Roman Mass

A large number of variable Proper Prefaces for the Mass are used in our Orthodox Western Rite; they contain significant didactic material on various theological matters.  In the Preface for the 22nd Sunday after the Octave Day of Pentecost, which one can also find in the Sacramentary of Robert of Jumieges, we have the following: 

"Maiestatem tuam suppliciter depraecantes, ut expulsis azymis vetustatis, ilius agni cybo satiemur et poculo, qui et nostram imaginem reparavit, et suam nobis gratiam repromisit, Iesus Christus Dominus noster.  Per quem..."

(...that, suppliantly beseeching Thy Majesty: that, having thrown away the unleavened bread [azymis] of the old dispensation [vetustatis=old age, old ways, etc], we may be filled with the Food and Drink of That Lamb That hath both repaired our appearance [imaginem] and again promised us His Grace, Jesus Christ Our Lord. Through Whom...)

This is a testimony to the old leavened bread in the Mass; the azyme (unleavened bread) of the Old Testament is removed, and, in its place, leavened bread is used.  
 

Prayer from Echternacht Sacramentary

 In the Sacramentary of Echternacht [9th century], as well as in the Ratoldus Sacramentary [late 9th / early 10th century], the Sacramentary of Minden [early 11th century], and many others, while the Sanctus [Holy, Holy, Holy, ...] is sung, all are directed to bow themselves, and the Priest [or Bishop] says this Prayer:

"O God, Who desirest not the death but the repentance of sinners, mayest Thou not drive me, a weak and miserable sinner, away from Thy Loving-Kindness, neither look Thou upon my sins and crimes, and impurities, and wicked thoughts, whereby I am lamentably separated from Thy Will, but for Thy Mercies, and for the faith and devotion of them, who through me, the sinner, desire Thy Mercy, and because Thou hast willed me, the unworthy one, to be between Thee and Thy people, make me so worthy, that, I may be able to beg mercy for me, and for them Thy people. And join our voices to the voices of Thine Holy Angels, that just as they do incessantly and tirelessly praise Thee in eternal blessedness, may we likewise thus by their intercession be made worthy to praise Thee blamelessly in this pilgrimage. Through Our Lord Jesus Christ Thy Son, Who liveth and reigneth with Thee, in the Unity of the Holy Ghost, God, through all the ages of ages. Amen."
