The Sacrament of the Altar is the true body and blood of our Lord Jesus Christ, under the bread and wine, instituted by Christ himself, for us Christians to eat and to drink.
The benefit which we receive from such eating and drinking is shown us by these words: “Given and shed for you for the remission of sins,” namely, that in the Sacrament forgiveness of sins, life and salvation are given us through these words. For where there is forgiveness of sins, there is also life and salvation.
It is not the eating and drinking that does this, but the words here written, “Given and shed for you for the remission of sins.” These words, along with the eating and drinking, are the main thing in the Sacrament; and whoever believes these words has exactly what they say, namely, the forgiveness of sins.
Fasting and bodily preparation are indeed a fine outward training; but he is truly worthy and well prepared who has faith in these words, “Given and shed for you for the remission of sins.” But he who does not believe these words, or doubts them, is unworthy and unprepared; for the words “for you” require truly believing hearts.
