The United States has never had a state church. American church attendance and church membership was very low, at about 30% of the population, until the revivals at the end of the eighteenth century and the beginning of the nineteenth century. The First Amendment of the Constitution, which is modeled on the older Virginia law of religious liberty, prohibits the establishment of a state religion. In fact, the words "Jesus Christ, Christianity, Bible, Creator, Divine, and God" are never mentioned in the Constitution-- not even once. Here's your list. Pick one and go there.
