Luther now entered boldly upon his work as a champion of the truth. His voice was heard from the pulpit in earnest, solemn warning. He set before the people the offensive character of sin, and taught them that it is impossible for man, by his own works, to lessen its guilt or evade its punishment. Nothing but repentance toward God and faith in Christ can save the sinner. The grace of Christ cannot be purchased; it is a free gift. He counseled the people not to buy indulgences, but to look in faith to a crucified Redeemer. He related his own painful experience in vainly seeking by humiliation and penance to secure salvation, and assured his hearers that it was by looking away from himself and believing in Christ that he found peace and joy.

As Tetzel continued his traffic and his impious pretensions, Luther determined upon a more effectual protest against these crying abuses. An occasion soon offered. The castle church of Wittenberg possessed many relics, which on certain holy days were exhibited to the people, and full remission of sins was granted to all who then visited the church and made confession. Accordingly on these days the people in great numbers resorted thither. One of the most important of these occasions, the festival of All Saints, was approaching. On the preceding day, Luther, joining the crowds that were already making their way to the church, posted on its door a paper containing ninety-five propositions against the doctrine of indulgences. He declared his willingness to defend these theses next day at the university, against all who should see fit to attack them. (GC 129.2) MC VC
