Dr. Luther’s Small Catechism lesson for the week of October 25, 2020:
[VI] THE SACRAMENT OF THE ALTAR
IN THE PLAIN FORM IN WHICH THE HEAD OF THE FAMILY
SHALL TEACH IT TO HIS HOUSEHOLD
How can bodily eating and drinking produce such great effects?
Answer: The eating and drinking do not in themselves produce them, but the words “for you” and “for the forgiveness of sins.” These words, when accompanied by the bodily eating and drinking, are the chief thing in the sacrament, and he who believes these words has what they say and declare: the forgiveness of sins.
