The passages quoted from the writings and addresses of Luther on marriage, are of special importance for the reason that these views are in strong contradiction with those that prevail to-day in the Church. In the struggle that it latterly has had to conduct with the clerical fraternity, the Social Democracy can appeal with full right to Luther, who takes on the question of marriage a stand free from all prejudice.
Luther and all the Reformers went even further in the marriage question, true enough, only for opportunist reasons, and out of complaisance towards the Princes whose strong support and permanent friendship they sought to secure and keep to the Reformation. The friendly Duke of Hessen, Philip I, had, besides his legitimate wife, a sweetheart, willing to yield to his wishes, but only under the condition that he marry her. It was a thorny problem. A divorce from the wife, in the absence of convincing reasons, would give great scandal; on the other hand, a marriage with two women at a time was an unheard of thing with a Christian Prince of modern days; it would give rise to no less a scandal. All this notwithstanding, Philip, in his passion, decided in favor of the latter step. The point was now to establish that the act did no violence to the Bible, and to secure the approval of the Reformers, especially of Luther and Melanchthon. The negotiations, set on foot by the Duke, began first with Butzer, who declared himself in favor of the plan, and promised to win over Luther and Melanchthon. Butzer justified his opinion with the argument: To possess several wives at once was not against the evangelium. St. Paul, who said much upon the subject of who was not to inherit the kingdom of God, made no mention of those who had two wives. St. Paul, on the contrary, said "that a Bishop was to have but one wife, the same with his servants; hence, if it had been compulsory that every man have but one wife he would have so ordered, and forbidden a plurality of wives." Luther and Melanchthon joined this reasoning, and gave their assent to double marriages, after the Duke's wife herself had consented to the marriage with the second wife under the condition "that he was to fulfil his marital duties towards her more than ever before."51 The question of the justification of bigamy had before then at the time when the issue was the consenting to the double marriage of Henry VIII of England caused many a headache to Luther, as appears from a letter to the Chancellor of Saxony, Brink, dated January, 1524. Luther wrote to him that, in point of principle, he could not reject bigamy because it ran not counter to Holy Writ;52 but that he held it scandalous when the same happened among Christians, "who should leave alone even things that are permissible." After the wedding of the Duke, which actually took place in March, 1540, and in answer to a letter of acknowledgment from him, Luther wrote (April 10): "That your Grace is happy on the score of our opinion, which we fain would see kept secret; else, even the rude peasants (in imitation of the Duke's example) might finally produce as strong, if not stronger, reasons, whereby we might then have much trouble on our hands."
Upon Melanchthon, the consent to the double marriage of the Duke must have been less hard. Before that, he had written to Henry VIII "every Prince has the right to introduce polygamy in his domains." But the double marriage of the Duke made such a great and unpleasant sensation, that, in 1541, he circulated a treatise in which polygamy is defended as no transgression against Holy Writ.53 People were not then living in the ninth or twelfth century, when polygamy was tolerated without shocking society. Social conditions had very materially changed in the meantime; in a great measure the mark had had to yield to the power of the nobility and the clergy; it had even extensively disappeared, and was further uprooted after the unhappy issue of the Peasant Wars. Private property had become the general foundation of society. Beside the rural population, that cultivated the soil, a strong, self-conscious handicraft element had arisen, and was dominated by the interests of its own station. Commerce had assumed large dimensions, and had produced a merchant class, which, what with the splendor of its outward position and its wealth, awoke the envy and hostility of a nobility that was sinking ever deeper into poverty and licentiousness. The burghers' system of private property had triumphed everywhere, as was evidenced by the then universal introduction of the Roman law; the contrasts between the classes were palpable, and everywhere did they bump against one another. Monogamy became, under such conditions, the natural basis for the sexual relations; a step such as taken by the Duke of Hessen now did violence to the ruling morals and customs, which, after all, are but the form of expression of the economic conditions that happen at the time to prevail. On the other hand, society came to terms with prostitution, as a necessary accompaniment of monogamy, and an institution supplemental thereto; and tolerated it.
In recognizing the gratification of the sexual impulses as a law of Nature, Luther but uttered what the whole male population thought, and openly claimed for itself. He, however, also contributed through the Reformation, which carried through the abolition of celibacy among the clergy, and the removal of the cloisters from Protestant territories that to hundreds of thousands the opportunity was offered to do justice to nature's impulses under legitimate forms. True again, due to the existing order of property, and to the legislation that flowed therefrom, hundreds of thousands of others continued to remain excluded. The Reformation was the first protest of the large-propertied bourgeois or capitalist class, then rising into being, against the restrictions imposed by feudalism in Church, State and society. It strove after freedom from the narrow bonds of the guild, the court and the judiciary; it strove after the centralization of the State, after the abolition of the numerous seats of idlers, the monasteries; and it demanded their use for practical production. The movement aimed at the abolition of the feudal form of property and production; it aimed at placing in its stead the free property of the capitalist, i. e., in the stead of the existing system of mutual protection in small and disconnected circles, there was to be unchained the free individual struggle of individual efforts in the competition for property.
On the religious field, Luther was the representative of these bourgeois aspirations. When he took a stand for the freedom of marriage, the question could not be simply about civic marriage, which was realized in Germany only in our own age through the civil laws and the legislation therewith connected, freedom to move, freedom of pursuit, and freedom of domicile. In how far the position of woman was thereby improved will be shown later. Meanwhile things had not matured so far at the time of the Reformation. If, through the regulations of the Reformation many were afforded the possibility to marry, the severe persecutions that followed later hampered the freedom of sexual intercourse. The Roman Catholic clergy having in its time displayed a certain degree of tolerance, and even laxity, towards sexual excesses, now the Protestant clergy, once itself was provided for, raged all the more violently against the practice. War was declared upon the public "houses of women;" they were closed as "Holes of Satan;" the prostitutes were persecuted as "daughters of the devil;" and every woman who slipped was placed on the pillory as a specimen of all sinfulness.
Out of the once hearty small property-holding bourgeois of the Middle Ages, who lived and let live, now became a bigoted, straight-laced, dark-browed maw-worm, who "saved-up," to the end that his large property-holding bourgeois successor might live all the more lustily in the nineteenth century, and might be able to dissipate all the more. The respectable citizen, with his stiff necktie, his narrow horizon and his severe code of morals, was the prototype of society. The legitimate wife, who had not been particularly edified by the sensuality of the Middle Ages, tolerated in Roman Catholic days, was quite at one with the Puritanical spirit of Protestantism. But other circumstances supervened, that, affecting, as they did, unfavorably the general condition of things in Germany, joined in exercising in general an unfavorable influence upon the position of woman.
