From the 20th Century

"Every thinking man, when he thinks, realizes that the teachings of the Bible are so interwoven and entwined with our whole civic and social life that it would be literally-I do not mean figuratively, but literally- impossible for us to figure what that loss would be if these teachings were removed. We would lose all the standards by which we now judge both public and private morals; all the standards towards which we, with more or less resolution, strive to raise ourselves."
President Theodore Roosevelt

"The foundations of our society and our government rest so much on the teachings of the Bible that it would be difficult to support them if faith in these teachings would cease to be practically universal in our country."
President Calvin Coolidge

"I just want to do God's will. And He's allowed me to go to the mountain. And I've looked over, and I've seen the promised land..."
Dr. Martin Luther King Jr.

"I shall allow no man to belittle my soul by making me hate him."
Booker T. Washington.

"America was born a Christian nation. America was born to exemplify that devotion to the elements of righteousness which are derived from the revelations of Holy Scriptures. Ladies and gentlemen, I have a very simple thing to ask of you. I as of every man and woman in this audience that from this night on they will realize that part of the destiny of America lies in their daily perusal of this great book of revelations. That if they would see America free and pure they will make their own spirits free and pure by this baptism of the Holy Scripture."
Woodrow Wilson, 1911, pre-Presidential campaign speech.

"The secret of my success? It is simple. It is found in the Bible, 'In all thy ways acknowledge Him and He shall direct thy paths."
George Washington Carver.

"If you will not have God (and He is a jealous God), you should pay your respects to Hitler and Stalin."
TS Elliot

"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 Harry S. Truman.

"History fails to record a single precedent in which nations subject to moral decay have not passed into political and economic decline. There has been either a spiritual awakening to overcome the moral lapse, or a progressive deterioration to ultimate national disaster"
General Douglas MacArthur

"Without God there is not virtue because there is no prompting of the conscience without God there is a coarsening of the society; without God democracy will not and cannot long endure. If we ever forget that we are One Nation Under God, then we will be a Nation gone under."
President Ronald Reagan
