This, then, is the faith we preach, of which the Turks and the pope and all the sectarians know nothing. The fanatics do, it is true, snatch to themselves the words of the angels, but how earnest they are is plain to see. For they receive the Word only as a piece of paper, as the cup and corporal receive the body and blood of Christ. The paper does no more than contain something and pass it on to others, but yet it remains paper. Thus you copy something from one paper on another paper; from my tongue the Word sounds in your ear, but it does not go to the heart. So they receive this greatest of treasures to their great harm and still think they are Christians, just as though the paper were to say: I certainly have in me the written words, “to you is born this day the Savior”; therefore I shall be saved. But then the fire comes and burns up the paper.
Therefore this is the chief article, which separates us from all the heathen, that you, O man, may not only learn that Christ, born of the virgin, is the Lord and Savior, but also accept the fact that he is your Lord and Savior, that you may be able to boast in your hear: I hear the Word that sounds from heaven and says: This child who is born of the virgin is not only his mother’s son. I have more than the mother’s estate; he is more mine than Mary’s, for he was born for me, for the angel said, “To you” is born the Savior. Then ought you to say, Amen, I thank thee, dear Lord.
