The position in which this country is placed, as the great exemplar of civil and religious liberty, makes it inexpressibly important, that the true principles on which this liberty rests, should be thoroughly understood. A responsibility lies on the citizens of this country, which no other nation ever sustained. Here it is to be demonstrated, that man can govern himself, and that religion can walk abroad in her own dignity and unsullied loveliness, as the messenger of God, armed with his authority, and wielding his omnipotence; that she can speak to the hearts of men with a voice of power, which owes no part of its emphasis to the force of human laws; that she, instead of leaning on the arm of the magistrate for support, can enter the halls of legislation, the cabinets of rulers, and the courts of justice, to spread out her laws, and proclaim her eternal sanctions. If civil liberty fail here, or if religion be overwhelmed with error or worldliness, the great cause of human happiness will suffer a disastrous check. It is believed, that a better knowledge of the principles of Roger Williams will have a salutary tendency, and that the publication of a memoir of his life is opportune, at this crisis, when, both in America and in Europe, the public mind is strongly agitated by questions which affect both the civil and the religious rights of men. If this book shall contribute, in the slightest degree, to the promotion of truth and freedom, I shall rejoice, and praise Him, who has restored my health, and given me leisure to finish the work. A word or two of explanation, on certain points, may be necessary. In the quotations from old documents, I have altered the orthography conformably to present usage. One reason for this course was, that scarcely any writer was consistent with himself, especially in relation to proper names. There is, too, nothing in orthography to mark the style of a particular writer, and it may, consequently, be altered, without affecting the idiomatic peculiarities of his composition, while the book is freed from the uncouth forms of words spelled according to antiquated fashions. The Indian names have been reduced to a uniform orthography, agreeably to what was believed to be the best form. They are spelled, in a most perplexing variety of ways, by different authors. Roger Williams himself sometimes spelled the same name differently in the same document. I have endeavored to arrange the dates according to the old style. Many mistakes have been committed, by various authors, from a neglect of this point. Before 1752, the year was computed to commence on the 25th of March, which was, accordingly, reckoned as the first month, and January and February were the eleventh, and twelfth. Dates between the 1st of January and the 25th of March, are usually, in this book, marked with both years. Thus the time of Mr. Williams’ arrival in America was the 5th of February, 1630–1.
