Did the Founders want us to be faithful to their faith?

The Founding Fathers had their own pack of tricks: they turned their backs on the past. If they had meekly inherited the faith of their fathers, they would have written a constitution establishing Christianity as the national religion. They did not.... At a time when all but two states required religious tests for office, the Constitution prohibited them. At a time when most states still had an official religion, the Bill of Rights forbade the federal government from establishing one.
