Donald J. D'Elia, The Spirits of '76: A Catholic Inquiry (1983).
From the publisher: In The Spirits of ’76, historian Donald D’Elia offers one of the most original sets of essays ever penned on seven of the greatest founding fathers. D’Elia analyzes the development of his figures’ philosophical and religious convictions. Thomas Jefferson, Benjamin Rush, John Adams, Charles Carroll of Carrollton, George Washington, Alexander Hamilton, and Benjamin Franklin are all presented here in an unusually revealing light.
