From the revolt of Henry VIII. against the Papacy down to the Revolution of 1688, there was in England a progressive movement toward liberal thought. It was at first a crude unconscious movement in the direction of toleration, which is a necessary condition for the development of free thinking. When we have arrived at a truly cordial toleration of opinions, allowing to all free play to stand or fall, just as hypotheses in science are suffered to stand or fall, then is men's thought for the first time really untrammelled. Whatever, therefore, tended toward toleration of diverse forms of creed or worship was a step in the path that led to free thinking; and whatever tended to democratize the church and relieve it from state control was a step toward toleration. The revolt of Henry VIII. at first but realized what the prœmunire statutes of Edward I. and Edward III. had threatened. But by breaking up the religious orders, expelling abbots from Parliament, and making the headship of the church a subject of fierce dispute, it contributed immensely to weaken and relax the bonds of conservatism, and it afforded a rare opportunity for the thoughts of laymen and small preachers to assert themselves. Thus the Lollardism which had been partially suppressed for more than a century now reared its head again defiantly, and, after learning lessons in democracy from Calvin, came forth as Puritanism, clad in full panoply for one of the world's most fateful contests.

In the course of Elizabeth's reign we find this Puritanism taking three different shapes. There were the moderate reformers, whose wish was simply to trim and prune the tree of Episcopacy; and secondly, those who were afterward known as "root and branch" men, whose name is descriptive enough. Instead of pruning they would uproot the tree and cast it away. To these Presbyterians the royal supremacy was no more than the papal a part of the living growth of Christ's church; it was but stubble fit for burning. Kings looked with horror upon such views, which threatened political danger no less than ecclesiastical. "A Scottish presbytery," cried James I., "agreeth as well with a monarchy as God and the Devil. Then Jack and Tom and Will and Dick shall meet, and at their pleasures censure me and my council and all our proceedings." The case could not have been more pithily stated, yet even Presbyterianism stopped short of full-fledged democracy. For Jack and his friends, by means of synods and general assemblies, could create a governing body with power of enforcing conformity upon unwilling congregations. In protest against this somewhat oligarchical method, Puritanism assumed its third form, that of Independency. The beginnings of Independency are to be sought among the Brownists of Elizabeth's reign, though their day of glory first came with the Civil War. In the theory of the Independents, as fully developed, any group of persons wishing to worship God in common might come together and organize themselves into a Congregational church, existing by as good a warrant as any other church, and entirely free from the control of any bishop, or synod, or council. No outside power could prescribe its creed or interfere with its ceremonial. Each church became, therefore, a little self-governing republic, as completely autonomous as an ancient Greek city, and the union of such churches was based solely upon the spirit of spontaneous Christian fellowship. Such was the theory of Independency.

In these successive stages of Protestantism we may see the preliminary steps toward general toleration and toward liberal thought. In each stage the strength of the coercive power that could be exercised over men's opinions and expressions of opinion was sensibly diminished. From the coercive power of the universal Church, which had once been able to direct a crusade against the Albigenses, it was a long step downward to the coercive power of Queen Elizabeth, whose will to suppress Puritanism was perpetually held in check by motives of public policy. It was a yet further step downward from the coercive power of a sovereign to that of a synod, and thence again to that of a congregation. So striking is the progress that one who knew nothing of history might easily mistake the theory of Independency as providing practically for something like complete toleration. History tells us that this was far from being the case. Heresy, or dissent from the commonly accepted orthodoxy, has been no more tolerated in Independent churches than elsewhere; and even in the absence of serious differences in dogma, persecution has been visited upon divergences from the customary ritual, as for example in the treatment long accorded to Baptists. In their militant days, neither Presbyterianism nor Independency ever professed to be tolerant. The gravest reproach they could imagine was to be charged with encouraging free thinking. The eminent Scottish divine Rutherford gave expression to the prevailing sentiment when he declared, "We regard toleration of all religions as not far removed from blasphemy." Nevertheless, the movement which gave rise to Presbyterianism and to Independency was sure to advance to the announcement of the principle of universal toleration. That movement was itself the expression of a vast amount of free thinking, and it was not to stop short of recognizing the claims of free thought. The century that witnessed the beginnings of an English-speaking America saw also the genuine principles of toleration laid down by Roger Williams and William Penn, and demonstrated with resistless wealth of learning and logic by Milton and Locke.

In an account of the origins of liberal thought in America this English development is all-important, but it does not cover the whole field. America's inheritance from Europe comes chiefly, but not entirely, from the British islands. In the early days of the Protestant Reformation, there were European countries in which religious toleration had advanced practically much further than in England. The England of Henry VIII. as compared with the Netherlands was in a crude and backward condition. The contrast might be likened to that between rural life with its narrow mental horizon and the varied cosmopolitan life of the city. England politically was a land of unrivalled promise, but she was not quite abreast with the most advanced culture of the time. Her government was mainly in the hands of country gentlemen, who lacked some valuable elements of experience that were possessed by the burghers of commercial Antwerp and Ghent. A careful survey of the Middle Ages shows plainly an abiding antagonism between commerce and the ecclesiastical spirit. A general connection between the predominance of international trade and the secularization of public life is distinctly traceable. On the map of mediæval Europe one may point out peculiar spots where the Papacy never gained complete sway. In some of these, as in Bohemia and southern Gaul, the resistance was due to Manichæan heresies brought in from the Eastern Empire, giving rise to a kind of mediæval Puritanism; in these we do not find a spirit of liberal thought developed, but rather an anti-Catholic fanaticism. The other peculiar spots lie in the great pathway of commerce between the Levant and the northern seas. In the free cities of northern Italy and southern Germany, in the Hansa towns, and in the Netherlands, priestcraft had less sway than elsewhere, and the general tone of thought was more liberal and modern. No city came so completely under the secularizing influences of maritime commerce as Venice; and it is significant that the Papacy, at the very pinnacle of its power and arrogance in the thirteenth century, utterly failed in its attempt to force the Inquisition upon that republic of merchants.

In similar wise, we find the commercial Netherlands in the sixteenth century exhibiting practically such toleration in matters of religion as the British islands attained only much later, and after prolonged and distressing struggle. From the time of Edward III. commercial intercourse with the great Dutch and Flemish cities was one of the most potent civilizing influences at work in England. It was a liberalizing influence in religion and in politics, and must be named among the causes which made the eastern counties preëminent for heresy. In later days, when the Dutch provinces had saved their Protestantism and recovered political freedom, they adopted a policy of toleration so broad as to seem to most contemporaries very eccentric. Their noble country was stigmatized as "the common harbour of all heresies" and a "cage of unclean birds." How it harboured heretics escaping from England is something that no American is ever likely to forget.

If, after this glance at European conditions, we cross the Atlantic and observe the group of twelve colonies that were planted during the seventeenth century, we find that five of them were especially notable for pursuing from the outset a policy of toleration,—a policy favourable to liberal thought. These five, naming them in order of seniority, were New Netherland, Maryland, Rhode Island, and Pennsylvania, with Delaware. In New Netherland the Dutch simply maintained their traditional secularized policy. On the hospitable island of Manhattan all the varieties of European religion met on terms of equality,—Lutherans and Catholics, Quakers[19] and Puritans, Moravians and Jews. After the English conquest this liberal policy was continued by the bigoted Duke of York, for reasons similar to those which made toleration a necessity in the province of the liberal and sagacious Calverts. The Catholic proprietors of Maryland wished to make their province a desirable home for Catholics who were inclined to leave England, and the only possible way of accomplishing this, without interference from the British government, was to pursue a policy broad enough to include Catholics along with all other kinds of Christians in its benefits. A similar necessity confronted Charles II. and James II. In order to secure as much protection as possible for Catholics without interference from Parliament, it was necessary to pursue a policy broad enough to include Quakers along with Catholics. For such reasons James refrained from disturbing the liberal Dutch policy in New York. For such reasons both Stuart kings supported the schemes of William Penn, in whose proprietary colonies of Pennsylvania and Delaware the principles of toleration were carried out, on the whole, more completely than anywhere else in English-speaking America. It is interesting in this connection to observe that the mother of William Penn was a Dutch lady, though perhaps it is possible to make too much of such a fact. The Quakers, who formed the strength of the colony, represented a phase of Puritanism more liberal than Independency. As contrasted with Independency, Quakerism was a notable advance in the direction of Individualism; it had outgrown the set of notions according to which a civic community ought to consist of a united body of believers. Pennsylvania, therefore, and its appendage Delaware, profited by the late date at which they were founded; they represented a more advanced stage of opinion than the colonies which started in the time of James I. Their proprietary government remained undisturbed until the Declaration of Independence, and in 1776 these two states were the only ones in which all Christians, whether Protestant or Catholic, stood socially and politically on an equal footing. For after the accession of William and Mary had made the Episcopal Church supreme in New York and Maryland, the Catholic inhabitants of those colonies were disfranchised and made the subject of various oppressive enactments. Even the laws of Rhode Island, as first printed, early in the eighteenth century, expressly prohibit Roman Catholics from voting. The date of this statute is not accurately known, but it was certainly between 1688 and 1705,[20] and may be due to the strong antagonism aroused by the conduct of James II. and his Jacobites. However that may be, the statute was not repealed until 1784.

The disfranchisement of Catholics was contrary to the spirit of the Rhode Island charter and to the views of Roger Williams, who certainly understood the rational grounds for religious toleration better than any other man of his time, save perhaps Milton and Vane. He represents the Protestant principle of the sacred right of private judgment carried out with unflinching logical consistency. In him the transition from Independency to Individualism is completed. The contrast between the two is illustrated in the controversy between Williams and Cotton which was called forth by the publication in 1644 of Williams's book entitled "The Bloudy Tenent of Persecution." John Cotton was a typical Independent, and by no means a man of persecuting temperament, but his view of the matter is extremely one-sided. He admits that it is wrong for error to persecute truth, but he holds it to be the sacred duty of truth to persecute error! Williams, on the other hand, sees that truth stands in no need of violent or artificial support, and that error contains within itself the seeds of death. He feels, too, that when I venture to persecute what I call error in others, I virtually assume my own infallibility. Thus not until pure Individualism is reached is the fundamental fallacy of Catholicism escaped. In order to protect this sacred Individualism, Williams would have a complete separation between church and state. Under no pretext whatever should the civil government interfere with religious matters. There should be no more statutes against heresy or heretics, no enforced attendance upon public worship, no support of churches by taxation. Roger Williams not only proclaimed such doctrines, but he lived up to them. He never took pains to conceal his dislike of Quaker doctrines; in his seventy-third year he once rowed himself in a boat the whole length of Narragansett Bay, in order to conduct a dispute against three valiant Quaker champions; yet, in spite of vehement pressure from the neighbouring colonies, he resolutely refused to allow the civil power of Rhode Island to be used against Quakers. Massachusetts in fury threatened to cut off the trade of the weaker colony, but nothing could intimidate Williams into what he termed "exercising a civil power over men's consciences." Among the public men of the seventeenth century Roger Williams deserves a preëminent place; he was the first to conceive thoroughly and carry out consistently, in the face of strong opposition, a theory of religious liberty broad enough to win assent and approval from advanced thinkers of the present day.

The separation of church from state, which was effected with such remarkable success in the founding of Rhode Island, did not become general in the United States until after the winning of independence. On this issue the eighteenth century had its memorable struggle, in which the protagonist was Virginia, and the victory was achieved under the leadership of Jefferson and Madison. The early policy of Virginia was to drive out dissentients, or subject them to civil disabilities; and of the Puritans who went thither for a while the greater part left the colony, many of them retreating into tolerant Maryland. After 1660, for three generations the Episcopal folk had it all their own way. But about 1720 began the wholesale immigration of Presbyterians and Lutherans into the Shenandoah Valley, and after the middle of the century trouble began when the tide-water Cavaliers tried to impose taxes upon these people for the support of the Established Church. The most numerous and powerful opponents of this narrow policy were the Presbyterians; and inasmuch as these had come, not from Scotland where their own church was established, but from Ireland where it was persecuted, their experience had led them to approve the separation of church from state. Their political notions were also strongly democratic, and with the aid of their votes Jefferson's party not only abolished primogeniture and entail and other old English customs, but also carried the disestablishment of the Episcopal Church in Virginia. Madison's Religious Freedom Act of 1785, which not only effected this, but likewise did away with all religious tests, is a very important event in the history of the United States. The statute, which declared that "opinion in matters of religion shall in no wise diminish, enlarge, or affect civil capacities," attracted attention far and wide; it was translated into several European languages, and published with admiring comments; and in the course of the next forty years it was imitated by one state after another, until all over the land religious freedom came to be almost as complete as legislation could make it. The qualifying adverb is still needed; for, by the constitutions of Pennsylvania and Tennessee, no man can hold office unless he believes in God and a future state of rewards and punishments; in Texas, Arkansas, Mississippi, the two Carolinas, and Maryland, belief in God is required; and in Arkansas and Maryland a man who does not believe in God and a future state of retribution is deemed incompetent as a witness or juror.[21] Such curiosities of law-making—survivals from a lower state, like the caudal vertebra in man and the higher apes—are common enough in history.

The various stages here mentioned in the progress toward religious toleration, and toward the separation of church and state, are important symptoms of the progress of liberal thought. Of course Madison's Religious Freedom Act could not have been proposed by an Endicott, or sustained by a community that would not endure the presence of Baptists or Quakers. The sketch here given shows an enormous advance in liberal thought in the course of two centuries and a half. But such a survey is far from telling us the whole story. A further inquiry into causal agencies is needed, and the best field for it is furnished by that theocratic Puritanism which cast out Roger Williams,—the Puritanism of the four confederated New England colonies, and especially of Massachusetts. No one can deny that in Massachusetts, during the nineteenth century, liberal thought has advanced further and has permeated the community more thoroughly than in any other state of the American Union. For at least three generations the intellectual ferment upon which liberal thought in the United States has thriven has come chiefly from Massachusetts. Yet among our colonies which attained social maturity during the seventeenth century there was none which made such emphatic exhibitions of intolerance and bigotry as Massachusetts. She was as clearly and avowedly founded upon an illiberal principle as Rhode Island was founded upon a principle of liberality. The Endicott type of mind is the very antipodes of the Roger Williams type; yet it was in the land of Endicott, and in a congenial soil, that Theodore Parker lately flourished. Whence came so great a change? The answer will remind us that there are two sources from which liberal thought is nourished. The one is the secularized Gallio spirit that deems it folly to interpose obstacles in the way of the natural working of reason and common sense; the other is the intense devotion to spiritual ideals which, in spite of all inherited encumbrances of bigotry and superstition, never casts off its allegiance to reason as the final arbiter. The former spirit is of vast use in the world, although its tendency is to deaden into mere worldliness as typified in a Franklin; the latter spirit may commit many an error, but its drift is toward light and stimulus and exaltation of life as typified in an Emerson. In the darkest days of New England Puritanism the paramount allegiance to reason was never lost sight of; and out of this fact came the triumph of free thinking, although no such result was ever intended.
