Quoting from a sermon of Dr. Martin Luther preached in his home on Maundy Thursday in 1534:
But the Sacrament of the Holy Supper was instituted not merely that by its observance Christ might be honored; for He can truthfully say: “I need not thy praise, I am the Son of God, whether thou glorifies me or not;” but also and especially for the reason that we stand in need of such a Testament and Supper, and that we might be benefited by it. Listen to the words with which He gives the bread: “Take, eat, this is my body, which is given for you,” and with which, soon after, He gives the cup: “Drink ye all of it; this cup is the New Testament in my blood, which is shed for you, for the remission of sins.”This declaration is the Christian’s most effective consolation; for he who really believes that Christ gave His body for him, and that He shed His blood for the remission of sins, cannot despair, no matter what sin, the world and the devil may say. He knows that this treasure wherewith his sins have been cancelled is far greater than all his iniquities.
This quote is taken from the inaugural edition of Logia in 1992, in an article titled “Two Sermons on the Holy Supper.” They in turn were quoting from the house postils, in this case from Sermons on the Gospels for the Sundays and Principal Festivals of the Church Year by Martin Luther, translated by E. Schmid and edited by M. Loy (Rock Island, Illinois: Augustana Book Company, 1871).
