It would be a mistake to judge him by his Latin writings, which, both in manner and style, seldom rise above the level of mediocrity. It is in his German books and pamphlets that Luther is seen at his best. There, he appears as a man of great ability and learning, gifted with a prodigious memory, a striking literary style, and a happy knack of seizing upon the weak points of his adversaries and of presenting his own side of the case in its most forcible and attractive form. No man knew better than he how to adapt himself to the tastes of his audience or the prejudices of his readers. He could play the role of the judge or the professor almost as well as that of the impassioned fanatic convinced that behind him were arrayed all the powers of Heaven. In dealing with men of education, who were not likely to be captivated by rhetoric, he could be calm and argumentative; but when he addressed himself to the masses of the people he appeared in his true character as a popular demagogue, hesitating at nothing that was likely to arouse their indignation against the Roman Church and their enthusiasm for the movement to which he had devoted his life. In words of fiery eloquence he recalled to their minds the real and imaginary grievances of their nation against Rome, the over-weening pride and tyranny of the spiritual princes, the scandalous lives of many of the ecclesiastics, and the failure of the Pope and councils to carry through a scheme of wholesale reform. He called upon them to throw off the yoke imposed by foreigners on their fathers and themselves, and to support him in his struggle for the liberty of the people, the independence of the German nation, and the original purity of the Gospel, promising them that if only they would range themselves under his banner, all their grievances, both spiritual and temporal, must soon be redressed. Had Luther never appeared, or had he been less gifted as an orator, a writer and a popular leader than he was, a crisis must have arisen at the time; but his genius and enthusiasm turned what might have been a trickling stream into a raging torrent, threatening destruction to beliefs and institutions hitherto regarded as inviolable. The time was ripe for a reformer, and Luther's only claim to greatness was his capacity of utilising in a masterly way the materials, political and religious, that lay ready at his hand. Religious abuses, social unrest, politics, personal vanities, and the excesses always attendant upon a great literary revival, were pressed into his service, and were directed against the Roman Church. And yet his success fell far short of his expectations. Beyond doubt he contrived to detach individuals and kingdoms from their obedience to the Pope and their submission to ecclesiastical authority only to subject them to the spiritual yoke of secular princes, and to expose them to doctrinal anarchy subversive of dogmatic religion; but the
