Ei ole mitään kaksia avaimia, niitä joita Jumala käyttelee taivaassa ja niitä joita pappi käyttelee maan päällä.
Since the days of the Apostles no teacher has preached these truths, that God forgives sins only through the Gospel and that faith must get the forgiveness of sins from the Gospel, so powerfully as Luther. Again and again he denounced the teaching, that there are “two keys.” He will not have the terrified sinner entertain such thoughts as these: Men on earth, unable to look into my heart, do indeed preach the Gospel to me and absolve me, but God, who searches the heart, is perhaps still angry with me. No, says Luther, there are not two keys, but only one. God alone, of course, can absolve from sin, but He will pronounce His absolution here on earth only through the Word of the Gospel. The Gospel is, wherever it is preached, God’s own Word, God’s own voice, regardless of how and by whom the Gospel comes to us. Luther denounces the idea of two keys as “utterly Pelagian, Turkish, heathenish, Jewish, Anabaptistic, fanatical, and Antichristian”; it is based on the assumption that the forgiveness of sins has not been fully earned by Christ and is not offered in the Gospel, but that it rests in whole or in part on the contrition and worthiness of man. Luther: "True, you must be contrite, but to think that the forgiveness of sins is to be made sure and the work of the key confirmed by your contrition means to forsake the faith and deny Christ [in His work of reconciliation]. He wants to forgive and remit your sins not for your sake, but for His own sake, from pure grace, by means of the key. (“Treatise on the Keys,” St. L. XIX:943 ff. ).
