Colonial Clergy John Wise, Thomas Hooker & John Witherspoon, who signed Declaration of Independence: "A Republic must either preserve its Virtue or lose its Liberty" - American Minute with Bill Federer
Calvin Coolidge stated: "In its main feature the Declaration of Independence is a great spiritual document ... Equality, liberty, popular sovereignty, the rights of man - these are not elements which we can see and touch ... They have their source and their roots in the religious convictions ... Unless the faith of the American in these religious convictions is to endure, the principles of our Declaration will perish. We cannot continue to enjoy the result if we neglect and abandon the cause ... If anyone wishes to deny their truth ... the only direction in which he can proceed ... is ... backward toward the time when there was no equality, no rights of the individual, no rule of the people ..
