No spirit of sect or of system must be looked for in this work. The latter is, perhaps, useful in a theological or a philosophical history; it allows us to measure all events and all opinions by one invariable standard, and to subordinate them to a high and controlling unity; but such has not been our design. Our office is that of a narrator rather than of a judge, and our purpose is to tell the history, not to make it speak in favour of a theory. One conceives that in ecclesiastical history generally, which has been told and re-told again and again, an author should endeavour to bring it back to a systematic point of view; that is the only way to give to his work a character of originality, and, so to speak, the reason for its existence. But for the history of the French Protestants, which has never been written as a whole, it was first requisite to collect and arrange the facts in a simple, clear, and impartial manner, without adopting a type, which might have distorted their nature. Other writers will follow who, finding these facts, will re-construct them by means of philosophy or theology. It was equally fitting that we should abstain from taking part in the questions, which divide Protestants among themselves. It was not for us to decide who was right or who wrong in these matters, and our pen would have betrayed our will, if, in the following pages, it could be supposed that any class of opinions would find an apology, or meet with an attack. Truth and justice are for all, as far as it has been possible for us to discern the true and the just: we could aspire to nothing less, and nothing more can be required of us. This impartiality is not the neutrality of indifference or sloth, or of what is sometimes called _impersonality_. In the great struggles of Protestantism, we are on the side of the oppressed against the oppressor, of the victims against their executioners, of right against brute force, of equality against privilege, and of liberty against despotism. The principle of the inviolability of the human conscience, which the peoples of modern times have gathered from the Gospel, is ours; and we shall esteem ourselves amply rewarded for our efforts, if the perusal of this work shall inspire, together with the sentiment of the happy effects of the Christian life, a deeper abhorrence of all religious persecution, under whatever name or pretext it may seek to cloak itself. Liberty of thought, liberty of faith, liberty of worship, under the safeguard and within the limits of common right: complete equality of religious creeds, and even above that equality itself, charity, fraternal love, which feels for the erring while reprobating their error—these are our maxims. They have constantly guided us in our labours, and God grant that our conviction may pass in its entirety into the spirit and conscience of the reader! The generation of our day is still in too much need of teaching of this kind.
