The Establishment Clause of the First Amendment is very simple at first reading.  It provides that "Congress shall make no law respecting an establishment of religion...."  Those ten words have spawned volumes and volumes of legal analysis, countless lawsuits and provided a key issue in the culture wars that keep America in constant turmoil.  

An interesting ruling came down affecting the Lehigh County government: today a federal judge ruled that the County's official seal, which includes a prominent yellow cross, violates the US Constitution, specifically the Establishment Clause.  The fallout from this ruling is unclear, and there will be more developments shortly.
