Religious leaders were not laid out in the Capitol.
One man—who was a religious leader, and also a cultural leader, a quasi diplomat, a globally admired spokesman against communism, a celebrity of lifelong personal humility and integrity, and an advisor to every President since Truman—was laid out in the Capitol.
Your comment exemplifies the current media-speak that communizes and collectivizes everything, generalizing outward from one single event as if it is a universal standard applying to all people in a broad general category. Graham was an unique individual and his life was uniquely excellent—another quality that socialism and collectivism rejects completely and finds offensive. Socialists hate excellence.
That is not the vision of the Founders, who believed in individual rights and responsibilities, individual freedoms and private property (including intellectual property), keeping the government out of religion, not the other way around. Thomas Jefferson institued Sunday church services in the Capitol Building for lawmakers. He also, as head of the public schools during his term, directed that the two books every child should have for lessons were the Bible and a hymnal.
How far we have fallen.
It depends on the Founder. Madison wanted ZERO religion in government. He opposed having chaplains in Congress and the military. I think he would have been opposed to this.
