O Lord, receive the soul of Your servant, Mark, who has departed from this earthly place to repose in Your Bosom; lead his soul to rest in a place of light, happiness, and peace, where there is neither pain nor suffering, neither grief nor sighing, but only life everlasting. And, as You are a gracious God and the Lover of Mankind, forgive him every sin he has committed by thought, or word, or deed, for there is not a man who lives and does not sin, for You alone are without sin and You are the Resurrection and the Life.
May his memory be eternal.
