“Yet, if the phrase “separation of church and state” appears in no official founding document, then what is the source of that phrase? And how did it become so closely associated with the First Amendment? On October 7, 1801, the Danbury Baptist Association of Danbury, Connecticut, sent a letter to President Thomas Jefferson expressing their concern that protection for religion had been written into the laws and constitutions. Believing strongly that freedom of religion was an inalienable right given by God, the fact that it appeared in civil documents suggested that the government viewed it as a government-granted rather than a God-granted right. Apprehensive that the government might someday wrongly believe that it did have the power to regulate public religious activities, the Danbury Baptists communicated their anxiety to President Jefferson.36 On January 1, 1802, Jefferson responded to their letter. He understood their concerns and agreed with them that man accounted only to God and not to government for his faith and religious practice. Jefferson emphasized to the Danbury Baptists that none of man’s natural (i.e., inalienable) rights – including the right to exercise one’s faith publicly – would ever place him in a situation where the government would interfere with his religious expressions.37 He assured them that because of the wall of separation, they need not fear government interference with religious expressions: Believing with you that religion is a matter which lies solely between man and his God, . . . I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should “make no law respecting an establishment of religion or prohibiting the free exercise thereof,” thus building a wall of separation between Church and State.38 In his letter, Jefferson made clear that the “wall of separation” was erected not to limit public religious expressions but rather to provide security against governmental interference with those expressions, whether private or public.”
