which came to be drawn between Attrition and Contrition» Until the thirteenth century it was always held that Contrition or a condition of real sorrow for sin was the one thing taken into account in the according of pardon to the sinner. The theologians of that century however began to make a distinction between Contrition, or godly sorrow, and Attrition, a certain amount of sorrow which might arise from a variety of causes of a more or less unworthy nature. It was held that this Attrition, though of itself too imperfect to win the pardon of God, could become perfected through the Confession heard by the priest and the Absolution administered by him. When this idea was placed in line with the thoughts developed as to the nature of the Sacrament of Penance, it followed that the weaker the form of sorrow and the greater the sins confessed and absolved, the heavier were the temporal penalties demanded by the righteousness of God. Indulgences appealed strongly to the indifferent Christian who knew that he had sinned, and who knew at the same time that his sorrow did not amount to Contrition. His conscience, however weak, told him that he could not sin with perfect impunity and that something more was needed than his perfunctory confession and the absolution of the priest. He felt that he must make some amends; that he must perform some satisfying act, or obtain an Indulgence at some cost to himself. Hence, for the ordinary indifferent Christian Attrition, Confession, and Indulgence, stood forth as the three great heads of the scheme of the Church for his salvation.
This doctrine of Attrition and its applications had not the undivided support of the Church of the later Middle Ages, but it was the doctrine which was taught by most of the Scotist divines who took the lead in theological thinking during these times. It was taught in its most pronounced form by such a representative man as John von Palz, who was professor of theology in the Erfurt monastery when Luther entered upon his monastic career; it was preached by the Indulgence sellers; it was specially valuable in securing good sales of Indulgences and therefore in increasing the papal profits. It lay at the basis of that whole doctrine and practice of Indulgences which confronted Luther when he felt~hhnself compelled to attack them.
The practice of Indulgences, on whatever theory they were upheld, had enmeshed the whole penitentiary system of the Church in the thirteenth, fourteenth, and fifteenth centuries. The papal power was at first sparingly used. It is true that in 1095 Pope Urban II promised an Indulgence to the Crusaders such as had never before been heard of-namely, a plenary Indulgence or a complete remission of all imposed canonical penances-but it was not until the thirteenth and fourteenth centuries that Indulgences were lavished by the Pope even more unsparingly than they had been previously by the Bishops. From the beginning of the thirteenth century they were promised in order to find recruits for wars against heretics, such as the Albigenses, against
