This short video explains why the Constitution is silent on religion. The Founders believed that religion was a matter best left to the states. As Professor Jeffry Morrison notes, the Founders were not unconcerned about religion, but a belief in federalism led them to allow individual states to make decisions about religious matters.
James Madison and Religion
This short video reviews James Madison’s attitudes towards religion. Although he believed that religious belief was essential in a virtuous republic, he also was a religious libertarian for whom God alone was the “lord of conscience.” Professor Jeffry Morrison suggests that Madison’s Calvinist teachers (e.g., Dr. John Witherspoon) shaped his belief that government should be blind toward religion.
