The correct reasoning for why the Framers included clauses in the Constitution that specifically excluded religion from government is that the Framers did this so that religious favoritism or persecution would not happen in the newly formed American government.
The Framers were heavily influenced by Enlightenment ideals and had observed the religious conflicts and persecutions in Europe. They sought to create a framework for government that protected individual freedoms, including the freedom of religion, and prevented any one religion from being favored or established by the government. This led to the establishment clause in the First Amendment, which prohibits the government from establishing a religion and ensures the free exercise of religious beliefs. By doing so, they aimed to create a diverse and pluralistic society where individuals could practice their own religions without fear of persecution or governmental interference.
