I don't know if cheerleader display of these signs violate the First Amendment. It's always seemed to me that the application to school sporting events of the establishment clause, intended to prevent Congress from establishing a national church, trivializes the First Amendment (not to mention frustrates the purpose of the framers, which was to protect state religious establishments from encroachments by Congress). But it is clear to me that these signs are an affront to anyone with a grain of religious sensibility. Does anyone really think that when the apostle Paul wrote "press on toward the goal to the win the prize for which God has called me in Christ Jesus" that he had in mind anything like scoring a touchdown in a football game? What a sacrilege! Next thing you know these cheerleaders will be exhorting their teams to "crucify" the opposition. If I were principal of a Christian school, with no concerns about transgressing the First Amendment, I couldn't have ordered these signs to be taken down fast enough.
