"Our notions of the separation of church and state owe a lot to Williams, a deeply pious Puritan clergyman who believed that civil authorities had no business enforcing religious views....In 1635, Williams founded Rhode Island as a haven of toleration and freethinking. Gaustad's timely little book reminds us that those are the enduring foundations of American civilization."—Time Magazine

"Excellent."—Booklist

"This is a little masterpiece. Gaustad knows the religious literature of colonial America as well as anyone. Despite being a professional historian, he can also write sentences that sing. Williams, he tells us, understood what Thomas Jefferson was to proclaim over a century later about freedom and the human spirit. The core of our liberal political heritage began as a religious argument about souls rather than citizens."—Joseph J. Ellis, author of His Excellence: George Washington

"As Gaustad makes clear in his remarkably succinct biography, Williams planted the seeds of ideas that would sprout a century after his death....He could have written several amendments to the Bill of Rights all by himself."—Milwaukee Journal Sentinel

"At once maddeningly original and disarmingly humane, Roger Williams championed Native American rights, church-state separation, and an independent judiciary when each was considered rank heresy. The justly noted historian Edwin S. Gaustad presents Williams's remarkable story in straightforward prose, without losing sight of its poetic power." —Forrest Church, author of The American Creed: A Biography of the Declaration of Independence and The Separation of Church and State: Writings on a Fundamental Freedom by America's Founders

"Energetic, elegant."—Providence Journal
