Voices of America

In Their Own Words

Thomas Jefferson
“I have always said and always will say that the studious perusal of the Sacred Volume will make better citizens, better fathers, better husbands... the Bible makes the best people in the world."
President
Harry Truman
"The fundamental basis of this nation's law was given to Moses on the Mount. The fundamental basis of our Bill of Rights comes from the teaching we get from Exodus and St. Matthew, from Isaiah and St. Paul. I don't think we emphasize that enough these days. If we don't have the proper fundamental moral background, we will finally end up with a totalitarian government which does not believe in the right for anybody except the state.
President
John Quincy Adams
“It is essential ... that you should form and adopt certain rules or principles, for the government of your own conduct and temper. Unless you have such rules and principles, there will be numberless occasions on which you will have no guide for your government but your passions ... It is in the Bible, you must learn them, and from the Bible how to practice them.”
President
Abraham Lincoln
"We have forgotten God. We have forgotten the gracious hand which preserved us in peace and multiplied and enriched and strengthened us, and we have vainly imagined, in the deceitfulness of our hearts, that all these blessings were produced by some superior wisdom and virtue of our own.
President
Ronald Reagan
"Politics and morality are inseparable. And as morality's foundation is religion, religion and politics are necessarily related. We need religion as a guide."
President
