I’ve heard lots of people say that America was founded on “judeo-Christian values” and that the founding fathers were Christian, and do it should be considered a fundamentally Christian nation. Others say that since freedom of religion is central to the constitution, America can’t really be a Christian nation. As an atheist, I tend to follow this side, but I wanna hear expert opinions. What’s the nuance to this? We’re all the founding fathers religious?
As you are waiting for a response, there are some earlier threads that may partially answer your question. You can read here about how the USA became more religious in the decades after its founding than it had been before, as explained by u/uncovered-history and based on some earlier answers. There is also this thread by u/ekmetzger which discusses the Founding Fathers' personal religious beliefs, and this one by u/TheExquisiteCorpse which focuses on their views on Islam and Muslims
