Prayer Before Partaking of the Holy Sacrament

O God, who art great, great in name and counsel, powerful in Thy works, the God and Father of Thy Holy Son Jesus, our Saviour, look upon us, Thy flock, which Thou hast chosen through Him to the glory of Thy Name; sanctify us in body and soul, and grant that we, being purified from all filthiness of flesh and spirit, may partake of the mystic blessings now going before Thee, and judge none of us unworthy of them, but be Thou our Supporter, our Helper, and Defender, through Thy Christ, with whom glory, honour, laud, praise, thanksgiving, be to Thee and the Holy Ghost forever.
