Thomas Jefferson on the Wall of Separation

"Because religious belief, or non-belief, is such an important part of every person's life, freedom of religion affects every individual. State churches that use government power to support themselves and force their views on persons of other faiths undermine all our civil rights. Moreover, state support of the church tends to make the clergy unresponsive to the people and leads to corruption within religion. Erecting the 'wall of separation between church and state,' therefore, is absolutely essential in a free society.

"We have solved ... the great and interesting question whether freedom of religion is compatible with order in government and obedience to the laws. And we have experienced the quiet as well as the comfort which results from leaving every one to profess freely and openly those principles of religion which are the inductions of his own reason and the serious convictions of his own inquiries."
