The History of the Reformation of the Sixteenth Century was received with cordiality on the Continent; but it has had a far greater number of readers in the British dominions and in the United States. The author looks upon the relations which this work has established between him and many distant Christians, as a precious reward for his labours. Will the present volume be received in those countries as favourably as the others? A foreigner relating to the Anglo-Saxon race the history of their Reformation is at a certain disadvantage; and although the author would rather have referred his readers to works, whether of old or recent date, by native writers, all of them more competent for the task than himself, he did not think it becoming him to shrink from the undertaking. At no period is it possible to omit the history of the Reformation in England from a general history of the Reformation of the Sixteenth Century; at the present crisis it is less possible than ever. In the first place, the English Reformation has been, and still is, calumniated by writers of different parties, who look upon it as nothing more than an external political transformation, and who thus ignore its spiritual nature. History has taught the author that it was essentially a religious transformation, and that we must seek for it in men of faith, and not, as is usually done, solely in the caprices of the prince, the ambition of the nobility, and the servility of the prelates. A faithful recital of this great renovation will perhaps show us that beyond and without the measures of Henry VIII there was something--everything, so to speak--for therein was the essence of the Reformation, that which makes it a divine and imperishable work. A second motive forced the author to acknowledge the necessity of a true History of the English Reformation. An active party in the Episcopalian Church is reviving with zeal, perseverance, and talent, the principles of Roman-catholicism, and striving to impose them on the Reformed Church of England, and incessantly attacking the foundations of evangelical Christianity. A number of young men in the universities, seduced by that deceitful _mirage_ which some of their teachers have placed before their eyes, are launching out into clerical and superstitious theories, and running the risk of falling, sooner or later, as so many have done already, into the ever-yawning gulf of Popery. We must therefore call to mind the reforming principles which were proclaimed from the very commencement of this great transformation.
