The pledge was written by a godless socialist evolutionist named Francis Julius Bellamy who claimed to be a Christian in the 1890's
Bellamy was also a free mason Little Falls Lodge No. 181 Little Falls, NY  source http://freemasonry.bcy.ca/biography/bellamy_f/bellamy_f.html  Thus making him no Christian at all but a luciferian.

In 1954, in response to the perceived threat of secular Communism, President Eisenhower encouraged Congress to add the words "under God," creating the 31-word pledge that is recited today
His original Pledge read as follows:    "I pledge allegiance to my Flag and to* the Republic for which it stands, one nation, indivisible, with liberty and justice for all"
Which was accompanied by a salute known as the Bellamy Salute and it was the same as hitler used.

It was officially replaced by the hand-over-heart salute when Congress amended the Flag Code on December 22, 1942. At a signal from the Principal the pupils, in ordered ranks, hands to the side, face the Flag. Another signal is given; every pupil gives the flag the military salute -- right hand lifted, palm downward, to a line with the forehead and close to it. Standing thus, all repeat together, slowly, “I pledge allegiance to my Flag and the Republic for which it stands; one Nation indivisible, with Liberty and Justice for all.” At the words, “to my Flag,” the right hand is extended gracefully, palm upward, toward the Flag, and remains in this gesture till the end of the affirmation; whereupon all hands immediately drop to the side.

—    In order to prevent further confusion or controversy, United States Congress instituted the hand-over-the-heart gesture as the salute to be rendered by civilians during the Pledge of Allegiance in the United States, instead of the Bellamy salute.^[2] This was done when Congress amended the Flag Code on December 22, 1942 In 1891, Bellamy was forced from his Boston by a congregation that disliked his tendency to describe Jesus as a socialist. Francis Bellamy was a leader in three related movement groups -- the public education movement, which sought to celebrate and expand public schools, the nationalist movement, which sought to nationalize public services and protect them from privatization, and the Christian socialist movement, which sought to promote an economy based on justice and equality.
