The main difference between the teachings of Luther and Kant is the distinction between autonomy and heteronomy. Luther believed that the outer-world was sinful and unholy. He felt that God was the only source of freedom in a human’s life and only faith in God will be the sole reason for someone to be saved: “We reach the conclusion that faith alone justifies us and fulfills the law; and this because faith brings us the spirit gained by the merits of Christ” (Luther 22).
