But with the firm establishment of Christianity edicts began to be issued by the Roman emperors making orthodox Christian belief the test of good citizenship. One who disagreed with the emperor and his religious advisers in regard to the relation of the three members of the Trinity was subject to prosecution. Heretical books were burned, the houses of heretics destroyed. So, organized mediaeval religious intolerance was, like so many other things, a heritage of the later Roman Empire, and was duly sanctioned in both the Theodosian and Justinian Codes. It was, however, with the Inquisition, beginning in the thirteenth century, that the intolerance of the Middle Ages reached its most perfect organization.
Heresy was looked upon as a contagious disease that must be checked at all costs. It did not matter that the heretic usually led a conspicuously blameless life, that he was arduous, did not swear, was emaciated with fasting and refused to participate in the vain recreations of his fellows. He was, indeed, overserious and took his religion too hard. This offensive parading as an angel of light was explained as the devil's camouflage. No one tried to find out what the heretic really thought or what were the merits of his divergent beliefs. Because he insisted on expressing his conception of God in slightly unfamiliar terms, the heretic was often branded as an atheist, just as to-day the Socialist is so often accused of being opposed to all government, when the real objection to him is that he believes in too much government. It was sufficient to classify a suspected heretic as an Albigensian, or Waldensian, or a member of some other heretical sect. There was no use in his trying to explain or justify; it was enough that he diverged.
There have been various explanations of mediaeval religious intolerance. Lecky, for example, thought that it was due to the theory of exclusive salvation; that, since there was only one way of getting to heaven, all should obviously be compelled to adopt it, for the saving of their souls from eternal torment. But one finds little solicitude for the damned in mediaeval writings. The public at large thought hell none too bad for one who revolted against God and Holy Church. No, the heretics were persecuted because heresy was, according to the notions of the time, a monstrous and unutterably wicked thing, and because their beliefs threatened the vested interests of that day.
We now realize more clearly than did Lecky that the Church was really a State in the Middle Ages, with its own laws and courts and prisons and regular taxation to which all were subject. It had all the interests and all the touchiness of a State, and more. The heretic was a traitor and a rebel. He thought that he could get along without the pope and bishops, and that he could well spare the ministrations of the orthodox priests and escape their exactions. He was the "anarchist", the "Red" of his time, who was undermining established authority, and, with the approval of all right-minded citizens, he was treated accordingly. For the mediaeval citizen no more conceived of a State in which the Church was not the dominating authority than we can conceive of a society in which the present political State may have been superseded by some other form of organization.
Yet the inconceivable has come to pass. Secular authority has superseded in nearly all matters the old ecclesiastical regime. What was the supreme issue of the Middle Ages—the distinction between the religious heretic and the orthodox—is the least of public questions now.
What, then, we may ask, has been the outcome of the old religious persecutions, of the trials, tortures, imprisonings, burnings, and massacres, culminating with the Revocation of the Edict of Nantes? What did the Inquisition and the censorship, both so long unquestioned, accomplish? Did they succeed in defending the truth or "safeguarding" society? At any rate, conformity was not established. Nor did the Holy Roman Church maintain its monopoly, although it has survived, purified and freed from many an ancient abuse. In most countries of western Europe and in our own land one may now believe as he wishes, teach such religious views as appeal to him, and join with others who share his sympathies. "Atheism" is still a shocking charge in many ears, but the atheist is no longer an outlaw. It has been demonstrated, in short, that religious dogma can be neglected in matters of public concern and reduced to a question of private taste and preference.
This is an incredible revolution. But we have many reasons for suspecting that in a much shorter time than that which has elapsed since the Inquisition was founded, the present attempt to eliminate by force those who contemplate a fundamental reordering of social and economic relations will seem quite as inexpedient and hopeless as the Inquisition's effort to defend the monopoly of the mediaeval Church.
We can learn much from the past in regard to wrong ways of dealing with new ideas. As yet we have only old-fashioned and highly expensive modes of meeting the inevitable changes which are bound to take place. Repression has now and then enjoyed some temporary success, it is true, but in the main it has failed lamentably and produced only suffering and confusion. Much will depend on whether our purpose is to keep things as they are or to bring about readjustments designed to correct abuses and injustice in the present order. Do we believe, in other words, that truth is finally established and that we have only to defend it, or that it is still in the making? Do we believe in what is commonly called progress, or do we think of that as belonging only to the past? Have we, on the whole, arrived, or are we only on the way, or mayhap just starting?
In the Middle Ages, even in the times of the Greeks and Romans, there was little or no conception of progress as the word is now used. There could doubtless be improvement in detail. Men could be wiser and better or more ignorant and perverse. But the assumption was that in general the social, economic, and religious order was fairly standardized.
This was especially true in the Middle Ages. During these centuries men's single objective was the assurance of heaven and escape from hell. Life was an angry river into which men were cast. Demons were on every hand to drag them down. The only aim could be, with God's help, to reach the celestial shore. There was no time to consider whether the river might be made less dangerous by concerted effort, through the deflection of its torrents and the removal of its sharpest rocks. No one thought that human efforts should be directed to making the lot of humanity progressively better by intelligent reforms in the light of advancing knowledge.
