First Amendment and Religion
The First Amendment has two provisions concerning religion: the Establishment Clause and the Free Exercise Clause. The Establishment clause prohibits the government from “establishing” a religion. The precise definition of “establishment” is unclear. Historically, it meant prohibiting state-sponsored churches, such as the Church of England. Today, what constitutes an “establishment of religion” is often governed under the three-part test set forth by the U.S. Supreme Court in Lemon v. Kurtzman, 403
