The first is, that the church must necessarily have exercised a very considerable influence upon moral and intellectual order in modern Europe, and upon public ideas, sentiments, and manners. That the fact is unquestionable, is proved by the moral and intellectual development of Europe being essentially theological. A survey of history from the fifth to the sixteenth century exhibits theology possessing and directing the human understanding, and giving its impress to all opinions: philosophical, political, and historical questions, were all considered under a theological point of view. The church was so supreme in the intellectual order, that even mathematical and physical sciences were held to be subject to its doctrines. The theological spirit was, as it were, the blood which flowed in the veins of the European world, until Bacon and Descartes—Bacon in England, and Descartes in France—were the first to carry intellect out of the beaten tracks of theology.
The same fact is found in all branches of literature; theological modes of thought, feeling, and expression, are displayed at every step.
Upon the whole, this influence was salutary. Not only did it keep up, and render productive, the intellectual movement in Europe, but the system of doctrines and precepts, under sanction of which it imparted the movement, was very superior to anything that the ancient world had known. Movement and advancement existed at one and the same time.
The situation of the church, furthermore, has given an extension and variety to the development of the human mind which it never had previously. In the East, intellectual progress was altogether religious; in the Greek society it was almost exclusively human; in the one, humanity, properly so called, its actual nature and destiny, completely disappeared; in the other, it was man himself, his immediate passions, sentiments, and interests, which occupied the whole stage. In the modern world, the religious spirit has mingled with all things, without excluding any. Modern intelligence is impressed at once with humanity and divinity. Human sentiments and interests hold a material place in our literatures, and yet the religious character of man—that portion of his existence which is directed to another world—appears at every step therein; insomuch that the two great sources of the development of man, humanity and religion, have flowed abundantly, and at the same time; so that, in spite of all the evil and all the abuses mixed up with it, in spite of all its acts of tyranny, in an intellectual point of view the church has exercised an influence more calculated for development than repression, for expansion than contraction.
In a political point of view, the matter is very different. There can be no doubt that by softening feelings and manners, by decrying and suppressing a great number of barbarous practices, the church powerfully contributed to the amelioration of the social state; but in the political order, as properly defined, in that which affects the relations of government with subjects, of power with liberty, I do not believe that, upon the whole, its influence has been beneficial. Under this head the church has always come forward as the interpreter and defender of two systems—the theocratical and the imperial—that is to say, of despotism, sometimes under a religious form, sometimes under a civil form. Taking all its institutions, its entire legislation—taking its canons, and its modes of procedure—the principle of theocracy, or of the old empire, is throughout found predominant. When weak, the church sheltered itself under the absolute power of the emperors; when strong, it claimed that absolutism on its own account, on the plea of its spiritual power. We need not linger in adducing facts or particular cases. There is no question that the church often invoked the rights of the people against the bad government of the sovereigns; it often even approved of, and stimulated, insurrections; and it likewise frequently advocated, in its intercourse with the sovereigns, the rights and interests of the people. But whenever the question of political guarantees has arisen between power and liberty, whenever attempts have been made to establish a system of permanent institutions, which might truly and effectually shelter liberty from the encroachments of power, the church has generally ranged itself on the side of despotism.
There is no occasion for much astonishment at this, or to charge upon the clergy an undue proportion of human weakness, or to imagine it a vice peculiar to the Christian church. It has a much deeper and more powerful origin.
What does every religion lay claim to? The governance of human passions and of human will. Every religion is a curb, a power, a government. It comes in the name of divine law to subdue human nature. Therefore human liberty is its especial antagonist, which it is its object to vanquish. To this purpose is its mission and hope directed.
But although religions have to struggle with human liberty, and although they aspire to cast the will of man in a new mould, at the same time they have no other moral means of acting upon man than what he himself supplies, than his own will and liberty. When they act by outward means, as by force or seduction—in other words, by means other than the free concurrence of man— they treat him as we would one of the elements, water or wind, as a purely physical or material power; and they fail in their object, for they do not thereby reach or influence the inclination. For religions really to accomplish their task, it is necessary that man yields himself up to them, but voluntarily and of his own free will, and that he preserves his liberty even amidst his submission. Religions are thus called to solve a double problem.
This they have too often overlooked. They have considered liberty as an obstacle, and not as a means; they have forgotten the nature of the force to which they were to address themselves, and have acted with the human soul as with a material object. It is in consequence of this error that they have been led to range themselves on the side of power or despotism against human liberty, regarding it only as an adversary, and straining much more to subdue it than to procure it guarantees. If religions had well considered their means of action, if they had not given way to a natural but deceitful tendency, they would have discovered that their province was to strengthen liberty, in order morally to control it, that religion can, and ought to act only by moral influences; and they would have respected the free will of mankind, whilst applying themselves to direct it. This they have not done, and in the end the religious influence has itself suffered as much as liberty.
