"Examine the religious principles which have, in fact, prevailed in the world, and you will scarcely be persuaded that they are anything but sick men's dreams."
-- David Hume
"A man is accepted into a church for what he believes and he is turned out for what he knows."
-- Mark Twain
"The most heinous and the most cruel crimes of which history has record have been committed under the cover of religion or equally noble motives."
-- Mohandas K. Gandhi
"Is it not strange that the descendants of those Pilgrim Fathers who crossed the Atlantic to preserve their own freedom of opinion have always proved themselves intolerant of the spiritual liberty of others?"
-- Robert E. Lee

And the one most germane to this thread:
"When a religion is good, I conceive it will support itself; and when it does not support itself, and God does not take care to support it so that its professors are obliged to call for help of the civil power, 'tis a sign, I apprehend, of its being a bad one. "
--Benjamin Franklin

P.S. For good measure, one more quote showing how foreign Pat's ideas would be to the Founders of the US:
"During almost fifteen centuries has the legal establishment of Christianity been on trial. What has been its fruit? More or less, in all places, pride and indolence in the clergy; ignorance and servility in the laity; in both, superstition, bigotry and persecution. "
--James Madison
