Page "History of religion in the United States" Paragraph 116

Currently, the Supreme Court applies a three-pronged test to determine whether legislation comports with the Establishment Clause, known as the " Lemon Test ".

First, the legislature must have adopted the law with a neutral or non-religious purpose.

Second, the statute's principal or primary effect must be one that neither advances nor inhibits religion.

Third, the statute must not result in an excessive entanglement of government with religion.
