In an oft quoted 1798 letter to the Massachusetts Militia, John Adams stated:
“Our constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other.”
Adams was a Unitarian who thoroughly embraced the Enlightenment and would over the course of his life grow more and more hostile to institutional Christianity. Like so many at that time he attended church services but (it could be argued) this was more a sense of social duty and moral principal than any notion of actual worship, communion, or submitting to revelation.
As such, it could be said that Adams typified the very kind of civic religion that continues to bedevil American society and has functioned to confuse and water down genuine Biblical faith.
Regardless this quote is often cited by the Evangelical Right as a justification for political action and a means of assessing contemporary American society.
