Don't know if you wanted to discuss the Pledge of Allegiance, so I will withhold lengthy comment. We should all note that "under God" wasn't part of the original pledge. Those words were added as a result of a petition by the Knights of Columbus in 1954. The original pledge was modeled on the Oath of Allegiance that Confederate soldiers were required to take in order to obtain release from prisoner-of-war camps.
By waging war on the South, people in the North believed they were doing God's will. The "Battle Hymn of the Republic" describes God in the forefront of invincible Northern soldiers led by Grant and Sherman, tramping down the grapes of wrath before His judgement seat. John Brown, who murdered Southerners in Kansas and attempted insurrection at Harpers Ferry, was lauded as a second Christ by respected Northern men like Ralph Waldo Emerson and Henry David Thoreau. Thoreau wrote of Brown's death: "Some 1800 years ago, Christ was crucified. This morning, Captain Brown was hung. He is not Old Brown any longer; he is an angel of light."
Just my opinion, but I don't see much happening "under God" in Washington and would prefer an independent Confederacy that remained free of the influence of the United States.
Recently my wife got some ribbing about being a Southerner and having to apply for employment as an alien national. Her response, "Well, we tried our best to make that happen!"
