The phrase "separation between church & state" comes from a letter written in 1802 by Thomas Jefferson, to the Danbury Baptist Association in Connecticut.
"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 & State."
Jefferson was repeating Roger Williams, who wrote in 1644, "A hedge or wall of separation between the garden of the church and the wilderness of the world."
