“Most people see America as an experiment in classical liberalism, whereby the founders created a system of limited government, religious pluralism and liberty. Religious leaders are free to spread their message through the culture—but not to take control of the levers of power and base lawmaking on their sectarian Bible interpretations. The Constitution protects everyone’s natural rights, with its main purpose limiting the sphere of government—not implementing rules to assure proper religious observance.
There really is no other way to seriously read our Constitution, but many religious people still argue the founders were Christians who envisioned a Christian nation. Some of the founders were indeed devout Christians and these folks cherry-pick Christian quotations from them.

Christian nationalists often argue that America cannot survive as a multicultural, multi-religious nation. To which I’ll quote a 1788 rebuttal from George Washington: “I had always hoped that this land might become a safe and agreeable asylum to the virtuous and persecuted part of mankind, to whatever nation they might belong.” As we approach the 250th anniversary of our founding, Americans must not let Washington’s brilliant legacy and the nation’s ideals get hijacked”
