For all you Theocrats laboring under the notion that devout Southern Baptist Reverend Thomas Jefferson, together with Deacon Benjamin Franklin, found the Pledge of Allegiance on a tablet of gold after a two week speaking-in-tongues session:
The Pledge of Allegiance was written by Francis Bellamy, who though Baptist minister, was a Christian Socialist. His cousin was socialist author Edward Bellamy.
Its original form was:
'I pledge allegiance to my Flag and the Republic for which it stands, one nation, indivisible, with liberty and justice for all.'
In 1954, Congress added the words 'under God' after a campaign from the Knights of Columbus.
