Lord Jesus Christ,
I approach your banquet table
in fear and trembling,
for I am a sinner,
and dare not rely on my own worth,
but only on your goodness and mercy.
I am defiled by many sins in body and soul,
and by my unguarded thoughts and words.
Gracious God of majesty and awe,
I seek your protection,
I look for your healing.
Poor troubled sinner that I am,
I appeal to you, the fountain of all mercy.
I cannot bear your judgment,
but I trust in your salvation.
Lord, I show my wounds to you
and uncover my shame before you.
I know my sins are many and great,
and they fill me with fear,
but I hope in your mercies,
for they cannot be numbered.
Lord Jesus Christ, eternal king, God and man,
crucified for mankind,
look upon me with mercy and hear my prayer,
for I trust in you.
Have mercy on me,
full of sorrow and sin,
for the depth of your compassion never ends.
Praise to you, saving sacrfice,
offered on the wood of the cross for me and for all mankind.
Praise to the noble and precious blood,
flowing from the wounds of the my crucified Lord Jesus Christ
and washing away the sins of the whole world.
Remember, Lord your creature,
whom you have redeemed with your blood;
I repent my sins,
and I long to put right what I have done.
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.
(This is St. Ambrose's prayer before Mass.)
