O GOD, Who makest the unworthy worthy, sinners righteous, impure pure: Work in me true repentance for my sins and misdeeds, for my daily and countless transgressions. Through faith in Thy Son, make me worthy to receive the sacrament of Thy Son’s Body and Blood for the cleansing of my soul and body of all shame and sin; through Him Who offered Himself to Thee, O God Father, the perfect propitiatory Sacrifice, Who is our sinless and only Mediator, through the High Priest, Jesus Christ, Thy dear Son. Amen. (adapted, Oremus, 1925, p.141).
