Dr. Luther’s Small Catechism lesson for the week of November 2, 2014:
[[VI] THE SACRAMENT OF THE ALTAR
IN THE PLAIN FORM IN WHICH THE HEAD OF THE FAMILY
SHALL TEACH IT TO HIS HOUSEHOLD
Who, then, receives this sacrament worthily?
Answer: Fasting and bodily preparation are a good external discipline, but he is truly worthy and well prepared who believes these words: “for you” and “for the forgiveness of sins.” On the other hand, he who does not believe these words, or doubts them, is unworthy and unprepared, for the words “for you” require truly believing hearts.
