The Golden Rule:

This country's principles of freedom of religion are based on Judeo-Christian ethics and standards, but not to the exclusion of non-Christian, or secular ethics that are commonly shared.
One of the founding fathers most important contribution to the preservation of religious freedoms was the concept, a Christian concept, of the separation of church and state.
