No man in Europe at the time had a more lively and impressive sense of the necessity of a general reformation than the monk of St.
Mark; but it was a reform in morals, not of doctrine. He saw the evils of the day--yea, of the Church itself--with perfect clearness, and demanded redress. He is as sad in view of these acknowledged evils as Jeremiah was in view of the apostasy of the Jews; he is as austere in his own life as Elijah or John the Baptist was. He would not abolish monastic institutions, but he would reform the lives of the monks,--cure them of gluttony and sensuality, not shut up their monasteries. He would not rebel against the authority of the Pope, for even Savonarola believed that prelate to be the successor of Saint Peter; but he would prevent the Pope's nepotism and luxury and worldly spirit,--make him once more a true "servant of the servants of God," even when clothed with the insignia of universal authority. He would not give up auricular confession, or masses for the dead, or prayers to the Virgin Mary, for these were indorsed by venerated ages; but he would rebuke a priest if found in unseemly places. Whatever was a sin, when measured by the laws of immutable morality, he would denounce, whoever was guilty of it; whatever would elevate the public morals he would advocate, whoever opposed. His morality was measured by the declaration of Christ and the Apostles, not by the standard of a corrupt age. He revered the Scriptures, and incessantly pondered them, and exalted their authority, holding them to be the ultimate rule of holy living, the everlasting handbook of travellers to the heavenly Jerusalem. In all respects he was a good man,--a beautiful type of Christian piety, with fewer faults than Luther or Calvin had, and as great an enemy as they to corruptions in State and Church, which he denounced even more fiercely and passionately. Not even Erasmus pointed out the vices of the day with more freedom or earnestness. He covered up nothing; he shut his eyes to nothing.
The difference between Savonarola and Luther was that the Saxon reformer attacked the root of the corruption; not merely outward and tangible and patent sins which everybody knew, but also and more earnestly the special principles of theology and morals which sustained them, and which logically pushed out would necessarily have produced them. For instance, he not merely attacked indulgences, then a crying evil, as peddled by Tetzel and others like him, for collecting money to support the temporal power of the popes or build St. Peter's church; but he would show that penance, on which indulgences are based, is antagonistic to the doctrine which Paul so forcibly expounded respecting the forgiveness of sins and the grounds of justification. And Luther saw that all the evils which good men lamented would continue so long as the false principles from which they logically sprung were the creed of the Church. So he directed his giant energies to reform doctrines rather than morals. His great idea of justification could be defended only by an appeal to the Scriptures, not to the authority of councils and learned men. So he made the Scriptures the sole source of theological doctrine. Savonarola also accepted the Scriptures, but Luther would put them in the hands of everybody, of peasants even,--and thus instituted private judgment, which is the basal pillar of Protestantism. The Catholic theologians never recognized this right in the sense that Luther understood it, and to which he was pushed by inexorable logic. The Church was to remain the interpreter of the doctrinal and disputed points of the Scriptures.
