Wittenberg was at that time the youngest of the German universities. It was founded in 1502 by the Elector Frederick the Wise of Saxony, a man pre-eminent among the German princes, not only from his prudence and circumspection, but also from his faithful care for his country, his genuine love for knowledge, and his deep religious feeling. His country was not a rich one. Wittenberg itself was a poor, badly-built town of about three thousand inhabitants. But the Elector showed his wisdom above all by his right choice of men whom he consulted in his work, and to whose hands he entrusted its conduct. These, in their turn, were very careful to select talented and trustworthy teachers for the institution, which was to depend for its success on the attractions offered by pure learning, and not those of outward show and a luxurious style of life among the students. The supervision of theology was entrusted by Frederick to Staupitz, whom personally he held in high esteem, and who, together with the learned and versatile Martin Pollich of Melrichstadt, had already been the most active in his service in promoting the foundation of the university. Staupitz himself entered the theological faculty as its first Dean. A constant or regular application to his duties was rendered impossible by the multifarious business of his Order, and the journeys it entailed. But in his very capacity of Vicar-General, he strove to supply the theological needs of the university, and, by the means of education thus offered, to assist the members of his Order. Already before this the Augustinian monks had had a settlement at Wittenberg, though little is known about it. A handsome convent was built for them in 1506. In a short time young inmates of this convent, and afterwards more monks of the same Order who came from other parts, entered the university as students and took academical degrees. The patron saint of the University was, next to the Virgin Mary, St. Augustine. Trutvetter of Erfurt became professor of theology at Wittenberg in 1507. It was early in the winter of 1508-9, when Staupitz, who had been re-elected for the second time, was still dean of the theological faculty, that Luther was suddenly and unexpectedly summoned thither. He had to obey not merely the advice and wish of an affectionate friend, but the will of the principal of his Order.

As hitherto he had simply graduated as a master in philosophy, and had not qualified himself academically for a professor of theology, Luther at first was only called on to lecture on those philosophical subjects which, as we have seen, occupied his studies at Erfurt. Theologians, it is true, had been entrusted with these duties, just as, here at Wittenberg, the first dean of the philosophical faculty was a theologian, and, in addition to that indeed, a member of the Augustinian Order. But from the beginning, Luther was anxious to exchange the province of philosophy for that of theology, meaning thereby, as he expressed it, that theology which searched into the very kernel of the nut, the heart of the wheat, the marrow of the bones. So far, he was already confident of having found a sure ground for his Christian faith, as well as for his inner life, and having found it, of being able to begin teaching others. Indeed, while busily engaged in his first lectures on philosophy, he was preparing to qualify himself for his theological degrees. Here also he had to begin with his baccalaureate, comprising in fact three different steps in the theological faculty, each of which had to be reached by an examination and disputation. The first step was that of bachelor of biblical knowledge, which qualified him to lecture on the Holy Scriptures. The second, or that of a Sententiarius, was necessary for lecturing on the chief compendium of mediaeval School-theology, the so-called Sentences of Peter Lombardus, the due performance of which duly led to the attainment of the third step. Above the baccalaureate, with its three grades, came the rank of licentiate, which gave the right to teach the whole of theology, and lastly the formal, solemn admission as doctor of theology. Already, on March 9, 1509, Luther had attained his first step in the baccalaureate. At the end of six months he was qualified, by the statutes of the university, to reach the second step, and in the course of the next six months he actually reached it.

But before gaining his new rights as a Sententiarius, he was summoned back by the authorities of his Order to Erfurt. The reason we do not know; we only know that he entered the theological faculty there as professor, receiving, at the same time, the recognition of the academical rank he had acquired at Wittenberg. At Erfurt he remained about three terms, or eighteen months. After that he returned to the university at Wittenberg. Trutvetter, towards the end of 1510, had received a summons back to Erfurt from Wittenberg. The void thus caused by his summons away may have had something to do with Luther's return thither. At all events his position at Wittenberg was now vastly different from that which he had previously held. No theologian, his superior in years or fame, was any longer above him.

Ere long, however, Luther received another commission from his Order; a proof of the confidence reposed also in his zeal for the Order, his practical understanding, and his energy. It was about a matter in which, by Staupitz's desire, other Augustinian convents in Germany were to enter into a union with the reformed convents and the Vicar of the Order. As opposition had been raised, Luther in 1511, no doubt at the suggestion of Staupitz, was sent on this matter to Rome, where the decision was to be given. The journey thither and back may easily have taken six weeks or more. According to rule and custom, two monks were always sent out together, and a lay-brother was given them for service and company. They used to make their way on foot. In Rome the brethren of the Order were received by the Augustinian monastery of Maria del Popolo. Thus Luther went forth to the great capital of the world, to the throne of the Head of the Church. He remained there four weeks, discharging his duties, and surrounded by all her monuments and relics of ecclesiastical interest.

No definite account of the result of the business he had to transact, has been handed down to us. We only learn that Staupitz, the Vicar of the Order, was afterwards on friendly relations with the convents which had opposed his scheme, and that he refrained from urging any more unwelcome innovations. For us, however, the most important parts of this journey are the general observations and experiences which Luther made in Italy, and, above all, at the Papal chair itself. He often refers to them later in his speeches and writings, in the midst of his work and warfare, and he tells us plainly how important to him afterwards was all that he there saw and heard.

The devotion of a pilgrim inspired him as he arrived at the city which he had long regarded with holy veneration. It had been his wish, during his troubles and heart-searchings, to make one day a regular and general confession in that city. When he came in sight of her, he fell upon the earth, raised his hands, and exclaimed 'Hail to thee, holy Rome!' She was truly sanctified, he declared afterwards, through the blessed martyrs, and their blood which had flowed within her walls. But he added, with indignation at himself, how he had run like a crazy saint on a pilgrimage through all the churches and catacombs, and had believed what turned out to be a mass of rank lies and impostures. He would gladly then have done something for the welfare of his friends' souls by mass-reading and acts of devotion in places of particular sanctity. He felt downright sorry, he tells us, that his parents were still alive, as he might have performed some special act to release them from the pains of purgatory.

But in all this he found no real peace of mind: on the contrary, his soul was stirred to the consciousness of another way of salvation which had already begun to dawn upon him. Whilst climbing, on his knees and in prayer, the sacred stairs which were said to have led to the Judgment-hall of Pilate, and whither, to this day, worshippers are invited by the promise of Papal absolutions, he thought of the words of St. Paul in his Epistle to the Romans (i. 17), 'The just shall live by faith. As for any spiritual enlightenment and consolation, he found none among the priests and monks of Rome. He was struck indeed with the external administration of business and the nice arrangement of legal matters at the Papal see. But he was shocked by all that he observed of the moral and religious life and doings at this centre of Christianity; the immorality of the clergy, and particularly of the highest dignitaries of the Church, who thought themselves highly virtuous if they abstained from the very grossest offences; the wanton levity with which the most sacred names and things were treated; the frivolous unbelief, openly expressed among themselves by the spiritual pastors and masters of the Church. He complains of the priests scrambling through mass as if they were juggling; while he was reading one mass, he found they had finished seven: one of them once urged him to be quick by saying 'Get on, get on, and make haste to send her Son home to our Lady.' He heard jokes even made about the priests when consecrating the elements at mass, repeating in Latin the words 'Bread thou art, and bread thou shalt remain: wine thou art, and wine thou shalt remain.' He often remarked in later years how they would apply in derision the term 'good Christian' to those who were stupid enough to believe in Christian truth, and to be scandalised by anything said to the contrary. No one, he declared, would believe what villanies and shameful doings were then in vogue, if they had not seen and heard them with their own eyes and ears. But the truth of his testimony is confirmed by those very men whose life and conduct so shocked and revolted him. He must have been indignant, moreover, at the contemptuous tone in which the 'stupid Germans' or 'German beasts' were spoken of, as persons entitled to no notice or respect at Rome.

He was astonished at the pomp and splendour which surrounded the Pope when he appeared in public. He speaks, as an eye-witness, of the processions, like those of a triumphing monarch. But the horrible stories were then still fresh at Rome of the late Pope Alexander and his children, the murder of his brother, the poisoning, the incest, and other crimes. Of the then Pope, Julius II., Luther heard nothing reported, except that he managed his temporal affairs with energy and shrewdness, made war, collected money, and contracted and dissolved, entered into and broke, political alliances. At the time of Luther's visit, he was just returning from a campaign in which he had conducted in person the sanguinary siege of a town. Luther did not fail to observe that he had established in the sacred city an excellent body of police, and that he caused the streets to be kept clean, so that there was not much pestilence about. But he looked upon him simply as a man of the world, and afterwards fulminated against him as a strong man of blood.

All these experiences at Rome did not, however, then avail to shake Luther's faith in the authority of the hierarchy which had such unworthy ministers; though, later on, when he was forced to attack the Papacy itself, they made it easier for him to shape his judgment and conclusions. 'I would not have missed seeing Rome,' he then declared, 'for a hundred thousand florins, for I might then have felt some apprehension that I had done injustice to the Pope. But as we see, we speak.'

During his visit he also roamed about among the ruins of the ancient capital of the world, and was astonished at the remains of bygone worldly splendour. The works of the new art which Pope Julius was then beginning to call into existence, did not appear to have particularly engaged his attention. The Pope was then progressing with the building of the new Church of St. Peter. The indulgence, of which the proceeds were to enable the completion of this vast undertaking, led afterwards to the struggle between the Augustinian monk and the Papacy.
