"I pledge allegiance to the flag of the United States of America and to the Republic for which it stands. One Nation, under God, indivisible, with liberty and justice for All."
"Under God" was added in 1954 by one of Joe McCarthy's neophytes to reassure backwater Americans that this was still a nation of red-blooded, bullet-headed Christians, not godless commies. The original pledge was written by Francis Bellamy, a Baptist preacher who also happened to be a socialist. He originally wanted to end the Pledge with "with liberty, equality, and fraternity for all", ie, the Jacobin pledge which was the motto of the French Revolution [which was nearing its centennial when he wrote the Pledge]. He scrapped it because, as he said, "We're a thousand years away from that."
