the profession or propagation of principles on supposition of their ill tendency, is a dangerous fallacy which at once destroys all religious liberty,' it is declared 'that it is time enough for the rightful purposes of civil government for its officers to interfere [only] when [religious] principles break out into overt acts against peace and good order.' In these two sentences is found the true distinction between what properly belongs to the church and what to the State.Reynolds was the first Supreme Court decision to use the metaphor "a wall of separation between Church and State." American historian George Bancroft was consulted by Chief Justice Morrison Waite in Reynolds regarding the views on establishment by the Founding Fathers. Bancroft advised Waite to consult Jefferson and Waite then discovered the above quoted letter in a library after skimming through the index to Jefferson's collected works according to historian Don Drakeman. The Establishment Clause forbids federal, state, and local laws which purpose is "an establishment of religion." The term "establishment" denoted in general direct aid to the church by the government. In Larkin v. Grendel's Den, Inc.

The First Amendment's framers knew that intertwining government with religion could lead to bloodshed or oppression, because this happened too often historically. To prevent this dangerous development they set up the Establishment Clause as a line of demarcation between the functions and operations of the institutions of religion and government in society.

The Establishment Clause thus serves to ensure laws, as said by Supreme Court in Gillette v. United States (1970), which are "secular in purpose, evenhanded in operation, and neutral in primary impact". The First Amendment's prohibition on an establishment of
