2. Penance and Indulgence.—The purpose of the disputation which Luther proposed to hold was to clear up the subject of the virtue of "indulgences," and the indulgences were the most striking and characteristic feature of the religious life of the Church in the last three Centuries of the Middle Ages.[12] We meet them everywhere—indulgences for the adoration of relics, indulgences for worship at certain shrines, indulgences for pilgrimages here or there, indulgences for contributions to this or that special object of charity. Luther roundly charges the indulgence-vendors with teaching the people that the indulgences as a means to the remission of sins. What are these indulgences? Their history is connected, on the one hand, with the history of the Sacrament of Penance, on the other with the history of the development of papal power. The Sacrament of Penance developed out of the administration of Church discipline. In the earliest days of the Church, the Christian who fell into sin was punished by exclusion from the communion of the Church. This excommunication was not, however, permanent, and the sinner could be restored to the privileges of Church-fellowship after he had confessed his sin, professed penitence, and performed certain penitential acts, chief among which were alms-giving, fasting and prayer, and, somewhat later, pilgrimage. These acts of penitence came to have the name of "satisfactions," and were a condition precedent to the reception of absolution. They varied in duration and severity, according to the enormity of the offence, end for the guidance of those who administered the discipline of the Church, sets of rules were formulated by which the "satisfactions" or "penances" were imposed. These codes are the "Penitential Canons." [13] The first step in the development of the indulgences may be found in the practice which gradually arose, of remitting some part of the enjoined "penances" on consideration of the performance of certain acts which could be regarded as meritorious.
