Do We Believe in the Separation of Church and State?

For a country that was apparently founded on the separation of church and state, US politics seems to be deeply enmeshed with Christianity. Now, Louisiana classrooms are required by state law to display the ten commandments…which definitely seems to be blurring the lines between church and state! Today we're talking about what the separation of church and state actually means, whether it's a concept ancient Christians would have recognized, and whether a religious foundation necessitates that a modern society be guided by religion.
