With the cessation of the pestilence and the return of his friends, the new year seems to have brought him also a salutary change in his physical condition; for his sufferings, which were caused by impeded circulation, became sensibly diminished.
Since the outbreak, and during the continuance of the plague, the work of Church visitation had been suspended. Melancthon, however, who had followed the university to Jena, was commissioned meanwhile to prepare provisionally some regulations and instructions for further action in this matter, and in August Luther received the articles which he had drafted for his examination and approval.
These articles or instructions comprised the fundamental principles of Evangelical doctrine, as they were henceforth to be accepted by the congregations. They were drawn up with especial regard to the 'rough common man,' who too often seemed deficient in the first rudiments of Christian faith and life, and with regard also to many of those confessing the new teaching, who, as Melancthon perceived, were not unfairly accused of allowing the word of saving faith to be made a 'cloak of maliciousness,' and who filled their sermons rather with attacks against the Pope than with words of edifying purport. Melancthon said on this point, 'those who fancy they have conquered the Pope, have not really conquered the Pope.' And whilst teaching that those who were troubled about their sins had only to have faith in their forgiveness for the merits of Christ, to be justified in the sight of God and to find comfort and peace, nevertheless, he would have the people earnestly and specially reminded that this faith could not exist without true repentance and the fear of God; that such comfort could only be felt where such fear was present, and that to achieve this end God's law, with its demands and threats of punishment, would effectually operate upon the soul.
Luther himself had taught very explicitly, and in accordance with his own experience of life, that the faith which saves through God's joyful message of grace could only arise in a heart already bowed and humbled by the law of God, and, having arisen, was bound to employ itself actively in fruits of repentance; although, in stating this doctrine, he had not perhaps so equally adjusted the conditions, as Melancthon had here done. An outcry, however, now arose from among the Romanists, that Melancthon no longer ventured to uphold the Lutheran doctrine; of course it suited their interests to fling a stone in this manner at Luther and his teaching. But what was far more important, an attack was raised against Melancthon from the circle of his immediate friends. Agricola of Eisleben, for instance, would not hear of a repentance growing out of such impressions produced by the Law and the fear of punishment. The conversion of the sinner, he declared, must proceed solely and entirely from the comforting knowledge of God's love and grace, as revealed in His message to man: thence, further, and thence alone, came the proper fear of God, a fear, not of His punishment, but of Himself. This distinction he had failed to find in Melancthon's Instructions. It was the first time that a dogmatic dispute threatened to break out among those who had hitherto stood really united on the common ground of Lutheran doctrine.
Luther, on the contrary, approved Melancthon's draft, and found little to alter in it. What his opponents said did not disturb him; he quieted the doubts of the Elector on that score. Whoever undertook anything in God's cause, he said, must leave the devil his tongue to babble and tell lies against it. He was particularly pleased that Melancthon had 'set forth all in such a simple manner for the common people.' Fine distinctions and niceties of doctrine were out of place in such a work. Even Agricola, who wished to be more Lutheran than Luther himself, was silenced.
Melancthon's work, after having been subjected by the Elector to full scrutiny and criticism in several quarters, was published by his command in March 1528, with a preface written by Luther, as 'Instructions of the Visitors to the parish priests in the Electorate of Saxony.' In this preface Luther pointed out how important and necessary for the Church was such a supervision and visitation. He explained, as the reason why the Elector undertook this office and sent out visitors, that since the bishops and archbishops had proved faithless to their duty, no one else had been found whose special business it was, or who had any orders to attend to such matters. Accordingly, the local sovereign, as the temporal authority ordained by God, had been requested to render this service to the gospel, out of Christian charity, since, in his capacity as civil ruler, he was under no obligation to do so. In like manner, Luther afterwards described the Evangelical sovereigns as 'Makeshift-bishops' (Nothbischöfe). At the same time the instructions for visitation introduced now in the smaller districts the office of superintendent as one of permanent supervision.
In the course of the summer preparations were made for a visitation on a large scale, embracing the whole country. The original intention had been to deal, by means of one commission, with the various districts in rotation. Such a course would have necessarily entailed, as was admitted, much delay and other inconveniences. A more comprehensive method was accordingly adopted, of letting different commissions work simultaneously in the different districts. Each of these commissions consisted of a theologian and a few laymen, jurists, and councillors of state, or other officials. Luther was appointed head of the commission for the Electoral district. The work was commenced earlier in some districts than in others. Luther's commission was the first to begin, on October 22, and apparently in the diocese of Wittenberg.
Luther had already, since May 12, voluntarily undertaken a new and onerous labour. Bugenhagen had left Wittenberg that day for the town of Brunswick, where, at the desire of the local magistracy, he carried out the work of reform in the Church, until his departure in October for the same purpose to Hamburg, where he remained until the following June. Luther undertook his pastoral duties in his absence, and preached regularly three or four times in the week. Nevertheless, he took his share also in the work of visitation; the district assigned to him did not take him very far away from Wittenberg. He remained there, actively engaged in this work, during the following months, and with some few intervals, up to the spring. From the end of January 1529 he again suffered for some weeks from giddiness and a rushing noise in his head; he knew not whether it was exhaustion or the buffeting of Satan, and entreated his friends for their prayers on his behalf, that he might continue steadfast in the faith.
The shortcomings and requirements brought to light by the visitation corresponded to what Luther had expected. In his own district the state of things was comparatively favourable; happily, a third of the parishes had the Elector for their patron, and in the towns the magistrates had, to some extent at least, fulfilled their duties satisfactorily. The clergy, for the most part, were good enough for the slender demands with which, under existing circumstances, their parishioners had to be content. But things were worse in many other parts of the country. A gross example of the rude ignorance then prevailing, not only among the country people, but even among the clergy, was found in a village near Torgau, where the old priest was hardly able to repeat the Lord's Prayer and the Creed, but was in high reputation far and near as an exorcist, and did a brisk business in that line. Priests had frequently to be ejected for gross immorality, drunkenness, irregular marriages, and such like offences; many of them had to be forbidden to keep beer-houses, and otherwise to practise worldly callings. On the other hand, we hear of scarcely any priests so addicted to the Romish system as to put difficulties in the way of the visitors. Poverty and destitution, so Luther reports, were found everywhere. The worst feature was the primitive ignorance of the common people, not only in the country but partly also in the towns. We are told of one place where the peasants did not know a single prayer; and of another, where they refused to learn the Lord's Prayer, because it was too long. Village schools were universally rare. The visitors had to be satisfied if the children were taught the Lord's Prayer, the Creed, and the Ten Commandments by the clerk. A knowledge of these at least was required for admission to the Communion.
Luther in the course of his visitations mixed freely with the people, in the practical, energetic, and hearty manner so peculiar to himself.
