State invocations of God are common in the United States; indeed, the national motto is “In God We Trust.” Yet the Establishment Clause forbids the state from favoring some religions over others. Nonetheless, courts have found the national motto and other examples of what is termed ceremonial deism constitutional on the ground that the practices are longstanding, have de minimis and nonsectarian religious content, and achieve a secular goal. Therefore, they conclude, a reasonable person would not think that the state was endorsing religion.
