This week, the trial of football coach Joseph Kennedy will be heard at the U.S. Supreme Court. Kennedy was fired after he repeatedly prayed at the 50-yard line after football games. According to Kennedy, he was saying a prayer of thanks for his team's performance: "That's where I made my commitment to God before I even took the coaching job. There on the field of battle." The case against Kennedy is that his public prayer was violating the first amendment's disestablishment clause -- otherwise known as the "separation between church and state." In his capacity as a public-school football coach, he used his platform and authority to endorse the Christian religion.
