We repeat and again reaffirm that neither a State nor the Federal Government can constitutionally force a person "to profess a belief or disbelief in any religion." Neither can constitutionally pass laws or impose requirements which aid all religions as against nonbelievers, and neither can aid those religions based on a belief in the existence of God as against those religions founded on different beliefs.

Hugo BlackThe "establishment of religion" clause of the First Amendment means at least this: Neither a state nor the Federal Government can set up a church. Neither can pass laws which aid one religion, aid all religions, or prefer one religion over another. Neither can force nor influence a person to go to or to remain away from church against his will or force him to profess a belief or disbelief in any religion.
Hugo BlackThe first ten amendments were proposed and adopted largely because of fear that Government might unduly interfere with prized individual liberties.

The amendments embodying the Bill of Rights were intended to curb all branches of the Federal Government in the fields touched by the amendments-Legislative, Executive, and Judicial.
