"To be sure, citizens in a robust democracy should expect to hear all manner of things that they do not like. But the First Amendment teaches that religious faith stands on a different footing from other forms of speech and observance. Because religious belief is so intimate and so central to our being, government advancement and effective endorsement of one faith carries a particular sting for citizens who hold devoutly to another."...
"As our nation becomes more diverse, so also will our faiths. To plant sectarian prayers at the heart of local government is a prescription for religious discord. In churches, homes, and private settings beyond number, citizens practice diverse faiths that lift and nurture both personal and civic life. But in their public pursuits, Americans respect the manifold beliefs of fellow citizens by abjuring sectarianism and embracing more inclusive themes. That the Board and religious leaders in Forsyth County hold steadfast to their faith is certainly no cause for condemnation. But where prayer in public fora is concerned, the deep beliefs of the speaker afford only more reason to respect the profound convictions of the listener."
