and the reverence of many Americans towards it, was forged by Major Robert Anderson's fight in defense of the flag at the Battle of Fort Sumter, which opened the American Civil War in April 1861. During the war the flag was used throughout the Union to symbolize American nationalism and rejection of secessionism. Goodheart explains the flag was transformed into a sacred symbol of patriotism: Soldiers and veterans An important dimension is the role of the soldiers, ready to sacrifice their lives to preserve the nation. They are memorialized in many monuments and semi-sacred days, such as Veterans Day and Memorial Day. Historian Jonathan Ebel argues that the "soldier-savior" is a sort of Messiah, who embodies the synthesis of civil religion, and the Christian ideals of sacrifice and redemption. In Europe, there are numerous cemeteries exclusively for American soldiers who fought in world wars. They have become American sacred spaces. Pacifists have made some sharp criticisms. For example, Kelly Denton-Borhaug, writing from the Moravian peace tradition, argues that the theme of "sacrifice" has fueled the rise of what she calls "U.S. war culture". The result is a diversion of attention from what she considers the militarism and the immoral, oppressive, sometimes barbaric conduct in the global American war on terror. Pledge of Allegiance Kao and Copulsky argue the concept of civil religion illuminates the popular constitutional debate over the Pledge of Allegiance. The function of the pledge has four aspects: preservationist, pluralist, priestly, and prophetic. The debate is not between those who believe in God and those who do not, but it is a dispute on the meaning and place of civil religion in America. Cloud explores political oaths since 1787 and traces the tension between a need for national unity and a desire to affirm religious faith. He reviews major Supreme Court decisions involving the Pledge of Allegiance, including the contradictory Minersville School District v. Gobitis (1940) and West Virginia v. Barnette (1943) decisions. He argues that the Pledge was changed in 1954 during the Cold War to encourage school children to reject communism's atheistic philosophy by affirming belief in God. School rituals Adam Gamoran (1990) argues that civil religion in public schools can be seen in such daily rituals as the pledge of allegiance; in holiday observances, with activities such as music and art; and in the social studies, history and English curricula.
