The appearance of Luther and the Reformation involved the decay of the Canon law system so far as Europe as a whole was concerned. It was for many reasons impossible for the Protestant reformers to retain formally either the Catholic conception of matrimony or the precariously elaborate legal structure which the Church had built up on that conception. It can scarcely be said, indeed, that the Protestant attitude towards the Catholic idea of matrimony was altogether a clear, logical, or consistent attitude. It was a revolt, an emotional impulse, rather than a matter of reasoned principle. In its inevitable necessity, under the circumstances of the rise of Protestantism, lies its justification, and, on the whole, its wholesome soundness. It took the form, which may seem strange in a religious movement, of proclaiming that marriage is not a religious but a secular matter. Marriage is, said Luther, "a worldly thing," and Calvin put it on the same level as house-building, farming, or shoe-making. But while this secularization of marriage represents the general and final drift of Protestantism, the leaders of Protestantism were themselves not altogether confident and clear-sighted in the matter. Even Luther was a little confused on this point; sometimes he seems to call marriage "a sacrament," sometimes "a temporal business," to be left to the state.[[332]] It was the latter view which tended to prevail. But at first there was a period of confusion, if not of chaos, in the minds of the Reformers; not only were they not always convinced in their own minds; they were at variance with each other, especially on the very practical question of divorce. Luther on the whole belonged to the more rigid party, including Calvin and Beza, which would grant divorce only for adultery and malicious desertion; some, including many of the early English Protestants, were in favor of allowing the husband to divorce for adultery but not the wife. Another party, including Zwingli, were influenced by Erasmus in a more liberal direction, and—moving towards the standpoint of Roman Imperial legislation—admitted various causes of divorce. Some, like Bucer, anticipating Milton, would even allow divorce when the husband was unable to love his wife. At the beginning some of the Reformers adopted the principle of self-divorce, as it prevailed among the Jews and was accepted by some early Church Councils. In this way Luther held that the cause for the divorce itself effected the divorce without any judicial decree, though a magisterial permission was needed for remarriage. This question of remarriage, and the treatment of the adulterer, were also matters of dispute. The remarriage of the innocent party was generally accepted; in England it began in the middle of the sixteenth century, was pronounced valid by the Archbishop of Canterbury, and confirmed by Parliament. Many Reformers were opposed, however, to the remarriage of the adulterous party. Beust, Beza, and Melancthon would have him hanged and so settle the question of remarriage; Luther and Calvin would like to kill him, but since the civil rulers were slack in adopting that measure they allowed him to remarry, if possible in some other part of the country.[[333]]

The final outcome was that Protestantism framed a conception of marriage mainly on the legal and economic factor—a factor not ignored but strictly subordinated by the Canonists—and regarded it as essentially a contract. In so doing they were on the negative side effecting a real progress, for they broke the power of an antiquated and artificial system, but on the positive side they were merely returning to a conception which prevails in barbarous societies, and is most pronounced when marriage is most assimilable to purchase. The steps taken by Protestantism involved a considerable change in the nature of marriage, but not necessarily any great changes in its form. Marriage was no longer a sacrament, but it was still a public and not a private function and was still, however inconsistently, solemnized in Church. And as Protestantism had no rival code to set up, both in Germany and England it fell back on the general principles of Canon law, modifying them to suit its own special attitude and needs.[[334]] It was the later Puritanic movement, first in the Netherlands (1580), then in England (1653), and afterwards in New England, which introduced a serious and coherent conception of Protestant marriage, and began to establish it on a civil base.

The English Reformers under Edward VI and his enlightened advisers, including Archbishop Cranmer, took liberal views of marriage, and were prepared to carry through many admirable reforms. The early death of that King exerted a profound influence on the legal history of English marriage. The Catholic reaction under Queen Mary killed off the more radical Reformers, while the subsequent accession of Queen Elizabeth, whose attitude towards marriage was grudging, illiberal, and old-fashioned, approximating to that of her father, Henry VIII (as witnessed, for instance, in her decided opposition to the marriage of the clergy), permanently affected English marriage law. It became less liberal than that of other Protestant countries, and closer to that of Catholic countries.

The reform of marriage attempted by the Puritans began in England in 1644, when an Act was passed asserting "marriage to be no sacrament, nor peculiar to the Church of God, but common to mankind and of public interest to every Commonwealth." The Act added, notwithstanding, that it was expedient marriage should be solemnized by "a lawful minister of the Word." The more radical Act of 1653 swept away this provision, and made marriage purely secular. The banns were to be published (by registrars specially appointed) in the Church, or (if the parties desired) the market-place. The marriage was to be performed by a Justice of the Peace; the age of consent to marriage for a man was made sixteen, for a woman fourteen (Scobell's Acts and Ordinances, pp. 86, 236). The Restoration abolished this sensible Act, and reintroduced Canon-law traditions, but the Puritan conception of marriage was carried over to America, where it took root and flourished.

It was out of Puritanism, moreover, as represented by Milton, that the first genuinely modern though as yet still imperfect conception of the marriage relationship was destined to emerge. The early Reformers in this matter acted mainly from an obscure instinct of natural revolt in an environment of plebeian materialism. The Puritans were moved by their feeling for simplicity and civil order as the conditions for religious freedom. Milton, in his Doctrine and Discipline of Divorce, published in 1643, when he was thirty-five years of age, proclaimed the supremacy of the substance of marriage over the form of it, and the spiritual autonomy of the individual in the regulation of that form. He had grasped the meaning of that conception of personal responsibility which is the foundation of sexual relationships as they are beginning to appear to men to-day. If Milton had left behind him only his writings on marriage and divorce they would have sufficed to stamp him with the seal of genius. Christendom had to wait a century and a half before another man of genius of the first rank, Wilhelm von Humboldt, spoke out with equal authority and clearness in favor of free marriage and free divorce.

It is to the honor of Milton, and one of his chief claims on our gratitude, that he is the first great protagonist in Christendom of the doctrine that marriage is a private matter, and that, therefore, it should be freely dissoluble by mutual consent, or even at the desire of one of the parties. We owe to him, says Howard, "the boldest defence of the liberty of divorce which had yet appeared. If taken in the abstract, and applied to both sexes alike, it is perhaps the strongest defence which can be made through an appeal to mere authority;" though his arguments, being based on reason and experience, are often ill sustained by his authority; he is really speaking the language of the modern social reformer, and Milton's writings on this subject are now sometimes ranked in importance above all his other work (Masson, Life of Milton, vol. iii; Howard, op. cit., vol. ii, p. 86, vol. iii, p. 251; C. B. Wheeler, "Milton's Doctrine and Discipline of Divorce," Nineteenth Century, Jan., 1907).

Marriage, said Milton, "is not a mere carnal coition, but a human society; where that cannot be had there can be no true marriage" (Doctrine of Divorce, Bk. i, Ch. XIII); it is "a covenant, the very being whereof consists not in a forced cohabitation, and counterfeit performance of duties, but in unfeigned love and peace" (Ib., Ch. VI). Any marriage that is less than this is "an idol, nothing in the world." The weak point in Milton's presentation of the matter is that he never explicitly accords to the wife the same power of initiative in marriage and divorce as to the husband. There is, however, nothing in his argument to prevent its equal application to the wife, an application which, while never asserting he never denies; and it has been pointed out that he assumes that women are the equals of men and demands from them intellectual and spiritual companionship; however ready Milton may have been to grant complete equality of divorce to the wife, it would have been impossible for a seventeenth century Puritan to have obtained any hearing for such a doctrine; his arguments would have been received with, if that were possible, even more neglect than they actually met. (Milton's scornful sonnet concerning the reception of his book is well known.)

Milton insists that in the conventional Christian marriage exclusive importance is attached to carnal connection. So long as that connection is possible, no matter what antipathy may exist between the couple, no matter how mistaken they may have been "through any error, concealment, or misadventure," no matter if it is impossible for them to "live in any union or contentment all their days," yet the marriage still holds good, the two must "fadge together" (op. cit., Bk. i). It is the Canon law, he says, which is at fault, "doubtless by the policy of the devil," for the Canon law leads to licentiousness (op. cit.). It is, he argues, the absence of reasonable liberty which causes license, and it is the men who desire to retain the privileges of license who oppose the introduction of reasonable liberty.

The just ground for divorce is "indisposition, unfitness, or contrariety of mind, arising from a cause in nature unchangeable, hindering, and ever likely to hinder, the main benefits of conjugal society, which are solace and peace." Without the "deep and serious verity" of mutual love, wedlock is "nothing but the empty husks of a mere outside matrimony," a mere hypocrisy, and must be dissolved (op. cit.).

Milton goes beyond the usual Puritan standpoint, and not only rejects courts and magistrates, but approves of self-divorce; for divorce cannot rightly belong to any civil or earthly power, since "ofttimes the causes of seeking divorce reside so deeply in the radical and innocent affections of nature, as is not within the diocese of law to tamper with." He adds that, for the prevention of injustice, special points may be referred to the magistrate, who should not, however, in any case, be able to forbid divorce (op. cit., Bk. ii, Ch. XXI). Speaking from a standpoint which we have not even yet attained, he protests against the absurdity of "authorizing a judicial court to toss about and divulge the unaccountable and secret reason of disaffection between man and wife."
