Church and State Issues
From dKosopedia
In the United States, the First Amendment of the Constitution provides that "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof." This differs from the protection to individuals regarding religion found in countries such as Canada where the right to freely exercise one's religion is protected, but the government is not prohibited from being involved in religion.
As a result, U.S. Government controlled schools may not have School Prayer, or a religious affiliation. Controversy has arisen over the Pledge of Allegiance as to whether the words "under God" (inserted in 1954) constitute the establishment of monotheism as the official religion of the United States.
