not modify the Pledge of Allegiance, or any other article or monument in our country, to remove from it the word "God".

It's not some old pledge, it's also a part of our recent history. Read:
"The Pledge of Allegiance of the United States is an oath of loyalty to the federal flag and the Republic of the United States of America, originally composed by Francis Bellamy in 1892 and formally adopted by Congress as the pledge in 1942. The Pledge has been modified four times since its composition, with the most recent change adding the words "under God" in 1954. Congressional sessions open with the recital of the Pledge, as do government meetings at local levels, meetings held by the National Exchange Club, Knights of Columbus, Royal Rangers, Boy Scouts of America, Girl Scouts of the USA, Fraternal Order of Eagles, Freemasons, Lions Club, Rotary Club and their concordant bodies, as well as other organizations."
