“It has often struck me with awe that some of the most deeply religious people I know have been, on the surface, atheists.”

The Philosophy of Paine (1925)
Context: He has been called an atheist, but atheist he was not. Paine believed in a supreme intelligence, as representing the idea which other men often express by the name of deity.
His Bible was the open face of nature, the broad skies, the green hills. He disbelieved the ancient myths and miracles taught by established creeds. But the attacks on those creeds — or on persons devoted to them — have served to darken his memory, casting a shadow across the closing years of his life.
When Theodore Roosevelt termed Tom Paine a "dirty little atheist" he surely spoke from lack of understanding. It was a stricture, an inaccurate charge of the sort that has dimmed the greatness of this eminent American. But the true measure of his stature will yet be appreciated. The torch which he handed on will not be extinguished.

Religiosamente mi reputo un teologo ateo.

Preface
The Great Rehearsal (1948)
Context: The most momentous chapter in American history is the story of the making and ratifying of the Constitution of the United States. The Constitution has so long been rooted so deeply in American life — or American life rooted so deeply in it — that the drama of its origins is often overlooked. Even historical novelists, who hunt everywhere for memorable events to celebrate, have hardly touched the event without which there would have been a United States very different from the one that now exists; or might have been no United States at all.
The prevailing conceptions of those origins have varied with the times. In the early days of the Republic it was held, by devout friends of the Constitution, that its makers had received it somewhat as Moses received the Tables of the Law on Sinai. During the years of conflict which led to the Civil War the Constitution was regarded, by one party or the other, as the rule of order or the misrule of tyranny. In still later generations the Federal Convention of 1787 has been accused of evolving a scheme for the support of special economic interests, or even a conspiracy for depriving the majority of the people of their liberties. Opinion has swung back and forth, while the Constitution itself has grown into a strong yet flexible organism, generally, if now and then slowly, responsive to the national circumstances and necessities.
