A. The holy apostles Matthew, Mark and Luke and St. Paulwrite this: “Our LordJesusChrist, in the night on which He was betrayed, took bread, gave thanks, broke it, gave it to His disciples and said: “Take! Eat! This is My body, which is given for you. Do this to remember Me!” In the same way He also took the cup after supper, gave thanks, gave it to them, and said: “Take and drink from it, all of you! This cup is the New Testament in my blood, which is shed for you to forgivesins. This do, as often as you drink it, to remember Me!”
Q. HOW CAN PHYSICAL EATING AND DRINKING DO SUCH GREAT THINGS?
A. Of course, eating and drinking do not do these things. These words, written here, do them: “given for you” and “shed for you to forgivesins.”
These words, along with physical eating and drinking are the important part of the sacrament. Anyone who believes these words has what they say and what they record, namely, the forgiveness of sins.
Q. WHO, THEN, RECEIVES SUCH A SACRAMENT IN A WORTHY WAY?
A. Of course, fasting and other physical preparations are excellent disciplines for the body. But anyone who believes these words, “Given for you,” and “Shed for you to forgivesins,” is really worthy and well prepared. But whoever doubts or does not believe these words is not worthy and is unprepared, because the words, “for you” demand a heart that fully believes.
