Glory to thee, O God. *(Thrice.)*
I thank thee, O Lord my God, that thou hast not rejected me, a sinner, but hast deemed me worthy to become a partaker of thy Holy Things. I thank thee that thou hast graciously granted unto me, though unworthy, to receive thy pure and heavenly Gifts. But, O Master who lovest mankind, who for our sake didst die, and didst rise again, and hast graciously bestowed upon us these terrible and life-giving Mysteries, for the blessing and sanctification of our souls and bodies: Vouchsafe that they may be efficacious for me also unto the healing of my soul and body, unto the averting of everything contrary thereto; unto the enlightenment of the eyes of my heart; unto the peace of my spiritual powers; unto faith invincible; unto love unfeigned; unto the fulfilling of wisdom; unto the keeping of thy commandments; unto the increase of thy divine grace and the attainment of thy kingdom: that by thee preserved in thy holiness I may ever bear in mind thy grace, and live not unto myself, but unto thee, our Master and Benefactor. And so, this life ended in the hope of life everlasting, I may come unto that rest eternal, where the voice of those who keep high festival ceaseth never, and where endless is the sweetness of those who behold the beauty inexpressible of thy countenance. For thou art the true desire and the happiness unutterable of those who love thee, O Christ our God, and every created being shall laud thee unto ages of ages. Amen.
From Isabel Florence Hapgood, Service Book of the Holy Orthodox-Catholic Apostolic Church, Houghton Mifflin, 1906, the Post-Communion Prayers, p. 123. The book itself — public domain.
“These terrible and life-giving Mysteries” uses terrible in its older sense — inspiring awe, not dreadful.
On the text. The scan gave “blessmg” for “blessing”, and a stray full stop in “me, a sinner, .but”. Both repaired.
Where these come from. Every prayer here is transcribed from a printed book that is out of copyright, and each one says which book and where in it. That is not fussiness. An English translation of an Orthodox prayer is a copyrighted work in its own right, separately from the Greek or Slavonic behind it, and in 2012 a monastery took a bishop to federal court for putting its translations on a website — and won. So these come from Hapgood's Service Book of 1906 and Shann's Euchology of 1891 and Book of Needs of 1894, which anyone may reprint. More on the sources and what is missing.
