The liturgy is the commemoration of the Last Supper when the Lord Jesus Christ at the Last Supper broke bread and gave it to his disciples with the words, Take, eat; this is my body, which is broken for you for the remission of sins. Then he took in his hands the cup of wine, gave thanks to his Father and gave it to his disciples to drink from, saying, Drink of this, all of you; this is my blood of the new covenant, which is shed for you and for many for the remission of sins.
