The Imperial Edicts issued against the innovations led him to speak more fully of the interference of the secular authorities on behalf of religious doctrine generally. “God,” he declares, “will permit none to rule over the soul but Himself alone.... Hence, when the secular power takes upon itself to make laws for the soul it is trespassing upon God’s domain and merely seducing and corrupting souls. We are determined to make this so plain that everyone can grasp it, and that our squires, Princes and bishops may see what fools they are when with laws and commandments they try to force the people to believe this or that.”[885] Such meddling of the authorities with matters which did not concern them was, so he says, due to the “commandments of men,” and was therefore utterly at variance with “God’s Word.” God would have “our faith founded only on His Divine Word,” but what the worldly authorities were after “was uncertain, or rather, certainly, displeasing [to God], because there was no clear Word of God in its favour.” “Such things are enjoined by the devil’s apostles, not by the Church, for the Church commands nothing save when she knows for certain that it is according to the Word of God.... As for them, they will find it a hard job to prove that the decrees of the Councils are the Word of God.”[886]

It is well worth our while to consider the following general grounds he assigns for his repudiation of all interference of the authorities in matters of faith, for, not long after, his position will be very different. He declares that, speaking generally, the authorities have “no power over souls”; the soul is removed altogether from the hands of men and “placed in the hands of God alone.” The ruler has just as little control over a soul as he has over the moon. “Who would not be accounted crazy who commanded the moon to shine at his pleasure?” Besides, Pope, Bishops and Schoolmen are “without God’s Word,” “and yet they wish to be termed Christian Princes, which may God prevent!” Further proofs follow from the Bible, where we read, that God alone knows and governs all things, and from the fact, that “every man’s salvation depends on his belief, and he must accordingly look to it that he believes aright”; “faith is a voluntary act to which no one can be forced, nay, it is a Divine work of the Spirit.” Moreover, “it is a vain and impossible thing” to compel the heart, and God will bring to a dreadful pass the purblind rulers who are now attempting it.[887]

His conclusion is that “the secular power must be content to wait and allow people to believe this or the other as they please and are able, and not to compel any man by force.”[888]

“Heresy can never be withstood by force,” he says further on. “Something else is needed.... God’s Word must here do the work, and if it fails, then the secular power will certainly not achieve it, though it should fill the world with blood.... God’s Word alone can be effective.” Hence the squires should learn at last to cease “destroying ‘heresy,’ and allow God’s Word which enlightens the heart” to have its way.[889]

Nevertheless, he admits that it is the right of the bishops to “restrain heretics.” “The bishops must do this, for it appertains to their office though not to the Princes”—a theory which Luther persistently refused to see carried to its logical conclusion. He also admits, that “no one has a right to command souls unless he knows how to show them the way to heaven,”—though here, again, he would have denied the consequence which Catholics gathered from this truth, when they urged that the measures adopted by the Empire against the innovations were for the safeguarding of the road to heaven, which an infallible Church points out to mankind. In Luther’s opinion there no longer existed any Church able to “point out the way to heaven” without danger of error. “This no man can do,” he exclaims in the same passage,[890] “but God alone.” It was hopeless for Catholics to argue that the Church did so only in God’s name, and under explicit promise of His assistance. Facts are there to prove that, at the very time when Luther was proclaiming his theories of religious toleration, he was setting them at nought in the most outrageous fashion where Catholics were concerned; he was, however, careful to veil his invitation to abolish their faith and worship under the specious pretext of demolishing abuses, sacrilege and the Kingdom of Antichrist. Nor was it long before he invoked the help of the secular power against sectarians within his own camp.

Where, towards the close of the work “On the secular power,” Luther passes on to show how Princes, who are “desirous of acting as Christian Princes and lords,” ought to administer their authority, he reaches a less controversial subject and is able to expound in that popular, imaginative language which he knew so well how to handle certain wholesome views which had already found expression in earlier times. In the forcible exhortations he here gives, rulers desirous of profiting might have found much to learn. Whoever wishes to be a Christian Prince must above all “lay aside the notion that he is to rule and govern by violence.” “Justice must reign at all times and in everything.” His whole mind must be set on “making himself of use and service to his subjects.” Secondly, “he must keep an eye on the Jacks-in-office and on his councillors, and behave towards them in such a way as not to despise any of them, while at the same time not confiding in any one man to such an extent as to leave everything to him.” “Thirdly, he must take care to deal rightly with evil-doers.” “He must not follow those advisers and fire-eaters who urge and tempt him to make war.” “Fourthly—what ought really to have been placed first— ... the ruler must behave towards his God as a Christian, submitting himself to Him with entire confidence, and praying for wisdom to rule well.”[891]

Concerning the latter point, viz. the attitude of the ruler towards God and towards religion, which, according to Luther, really should come first, the exhortations of earlier days addressed to the rulers, hardly ever failed to represent the protection of the Kingdom of God as the noblest task of any sovereign, who looked beyond temporal things to the world to come. Luther himself at a later period commends the protection and extension of the Kingdom of God most earnestly and eloquently to all rulers who followed the new faith, and instances the example of the Jewish Kings and Jewish priesthood.[892] Here, however, where he is full of other interests, we find not a word of the kind. On the subject of their relation to God, all he does is to remind the Princes in one sentence of the need of “true confidence and heartfelt prayer,” and, having done so, he breaks off and hurriedly brings the work to an end. In this circumstance, in itself insignificant, Luther’s violent breach with tradition is very apparent. Here, where, for the first time in any work of his, he puts forth his views as to what the conduct of secular authorities should be, in dealing with their relations to faith and worship, he has not a word in support of the recommendation to protect religion, albeit so justifiable and hitherto so usual; he could not give such a recommendation, because a few pages before he had laid it down that “the secular government has laws which do not extend beyond life and property and what is external on earth.” “The secular power must leave people free to believe this or that as they please”; “the blind, miserable wretches [the Catholic Princes] see not how vain and impossible a thing they are undertaking.”[893]—Nowhere in the writing, as a Protestant theological critic remarks, “does the idea appear that a Christian ruler has the right or the duty to pass beyond the limits of his temporal jurisdiction and to concern himself with ecclesiastical matters.”[894]

It is quite remarkable how Luther reduces the action of the secular power and the rights of the authorities to a judicial constraint to be exercised against evil-doers, or, as he says, to the task of a mere executioner.

For the explanation of these ideas on the secular power, two points are of especial importance: In the first place, Luther was at that time somewhat disappointed with the Princes and the nobles. In his work “To the Nobility” he had urged them to make an end of the Papal rule, and now he was vexed to see that, almost to a man, they had declined to do anything, whilst he himself was under the ban of the Empire. Secondly, it was his idea of the inward action of the Evangel upon souls and his conception of a sort of invisible Church, which induced him to exclude altogether the secular power from the spiritual domain, and to speak in exaggerated and disparaging terms of the “outward actions” with which alone it was concerned. In those years, when he was still to some extent under the influence of his early pseudo-mysticism, he was fond of picturing to himself the community of believers as an assembly of all those who had been awakened by “the Word,” and who, in spirit, were far above the compulsion of any earthly regulations. Thus, with him, the Church, in comparison with the political community, tended to evaporate into a mere union of souls, scarcely perceptible to earthly eyes.[895]

To us now it is clear that, in spite of every effort to the contrary, the new Church was bound in process of time to become entirely dependent on the secular power, first and foremost in its outward administration. Luther’s spiritual Church could not endure but for the support of the authorities.
