The U.S. Supreme Court ruled in Greece v. Galloway that local governments can open their meetings with ceremonial prayer, including religion-specific references. But public officials and citizens should understand the court also made clear in this ruling that the First Amendment imposes important limits on the practice of ceremonial prayer:
Nothing in the decision requires local legislative bodies to open with prayers. Many municipalities have discontinued the practice, feeling it always favors some point of view over others. Municipalities that choose to continue with the practice are advised to follow the practice of the U.S. Congress, which asks invocation-givers to be mindful of religious diversity.
