Eternal Father, we offer you the sacrifice wherein your Son Jesus offered Himself upon the Cross and which He now renews upon this altar.
We adore you and render to you that honor which is your due, acknowledging your dominion over all things and our absolute dependence on you.
You are our first beginning and our last end;
we give you thanks for countless benefits received;
we ask you to forgive our sins and to offer you worthy satisfaction for the same;
Finally to implore your grace and mercy for all of us who will offer this sacrifice today, for all those who are in tribulation and distress, for all of us sinners,
for the whole world and for the souls in purgatory.
We ask this through Christ our Lord.
Amen.
St. Charles Borromeo
