But he possessed a genius naturally vast and penetrating, a memory quick and tenacious, patience inexhaustible, and a fund of learning very considerable for that age: above all, he had an erect and daring spirit, fraught with magnanimity and grandeur, and loving nothing so well as truth; so that his understanding was ever prepared to expand with the occasion, and his principles to change or rise, according to the increase and elevation of his knowledge. Nature had endued him with an ardent soul, a powerful and capacious understanding; education had chilled the one and contracted the other; and when he came forth into the fields of controversy, he had many of those trammels still hanging about him, which patience, and a succession of exertions, and the excitement of dispute, at length enabled him for the most part to cast away.
In the year 1517, John Tetzel, a Dominican Monk, was preaching in Germany the indulgences of Pope Leo X.; that is, he was publicly selling to all purchasers remission of all sins, past, present, or future, however great their number, however enormous their nature. The expressions with which Tetzel recommended his treasure appear to have been marked with peculiar impudence and indecency. But the act had in itself nothing novel or uncommon: the sale of indulgences had long been recognized as the practice of the Roman Catholic Church, and even sometimes censured by its more pious, or more prudent members. But the crisis was at length arrived in which the iniquity could no longer be repeated with impunity. The cup was at length full; and the hand of Luther was destined to dash it to the ground. In the schools of Wittemberg the Professor publicly censured, in ninety-five propositions, not only the extortion of the Indulgence-mongers, but the co-operation of the Pope in seducing the people from the true faith, and calling them away from the only road to salvation.
This first act of Luther’s evangelical life has been hastily ascribed by at least three eminent writers of very different descriptions, (Bossuet, Hume, and Voltaire,) to the narrowest monastic motive, the jealousy of a rival order. It is asserted that the Augustinian Friars had usually been invested in Saxony with the profitable commission, and that it only became offensive to Luther when it was transferred to a Dominican. There is no ground for that assertion. The Dominicans had been for nearly three centuries the peculiar favourites of the Holy See, and objects of all its partialities; and it is particularly remarkable, that, after the middle of the fifteenth century, during a period scandalously fruitful in the abuse in question, we very rarely meet with the name of any Augustinian as employed in that service. Moreover, it is almost equally important to add, that none of the contemporary adversaries of Luther ever advanced the charge against him, even at the moment in which the controversy was carried on with the most unscrupulous rancour.
