The Supreme Court was split on the issue of displaying the Ten Commandments on government land:

The Supreme Court ruled today that displaying the Ten Commandments on government property does not necessarily violate the constitutional principle that there must be a separation between church and state.

In one of the cases, Chief Justice Rehnquist wrote: “While the Commandments are religious, they have an undeniable historical meaning. Simply having religious content or promoting a message consistent with a religious doctrine does not run afoul of the Establishment Clause.”

The Judeo-Christian god has now been reduced (or promoted, depending on your religious beliefs) to the status of historical and not necessarily religious meaning?

I doubt that even Zeus would put up with that.
