Prayer of St. Basil the Great after Holy Communion

Lord Christ our God, King of the ages and Creator of all, I thank Thee
for all the blessings Thou hast granted me and for the communion of Thy
pure and life-giving Mysteries. I pray Thee, therefore, good Lord and
Lover of men, guard me under Thy protection and within the shadow of
Thy wings; and grant me with a clear conscience till my last breath worthily
to partake of Thy holy Things for forgiveness of sins and for life eternal.
For Thou art the Bread of Life, the Source of Holiness, the Giver of
all that is good, and to Thee we send up the glory, with the Father and
the Holy Spirit, now and ever, and to the ages of ages. Amen.
