“Merciful Father, take away all my offenses and sins; purify me in body and soul, and make me worthy to taste the holy of holies. May your body and blood, which I intend to receive, although I am unworthy, be for me the remission of my sins, the washing away of my guilt, the end of my evil thoughts, and the rebirth of my better instincts. May it incite me to do the works pleasing to you and profitable to my health in body and soul, and be a firm defense against the wiles of my enemies. Amen.”   - St Ambrose  Prayer before communion.
