do, as often as you drink it, to remember Me!'"

What good does this eating and drinking do?

These words tell us: "Given for you" and "Shed for you to forgive
sins." Namely, that the forgiveness of sins, life and salvation are
given to us through these words in the sacrament. Because, where sins
are forgiven, there is life and salvation as well.

How can physical eating and drinking do such great things?

Of course, eating and drinking do not do these things. These words,
written here, do them: "given for you" and "shed for you to forgive
sins." 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.

Who, then, receives such a sacrament in a worthy way?

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 forgive sins," 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.
