America is a Christian nation?

Well no where in the Constitution does it say that religion and the state must be separate. It says that the government will not establish a religion. Meaning it will not show favoritism for one over another. The reason America was created was due to a split in Christianity. Some believed one way and others another way. Even England has a state sponsored religion, The Church of England. They wanted people to feel free to worship the way they felt was best. So the government could not say that America is a Catholic nation or a Baptist nation. I do not see why we could not say that Christianity is the religion of America, as long as we do not declare one group or denomination over another. Also as long as we permit other citizens to practice what ever religion they like, and do not make them a second cl group. Other than that I think we should say America is a Christian nation and our founding faith was and is that of Christianity.
