“Believing with you that religion is a matter which lies solely between Man & his God, that he owes account to none other for his faith or his worship, that the legitimate powers of government reach actions only, & not opinions, 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” Thomas Jefferson author of the Virginia Statute of Religious Freedom that Madison used for inspiration.
Separation of Church and State is a foundational principle of this Republic. One essential to it being a FREE Republic.
Sure worked for the Soviet Republic.
