"The day commemorates the enactment of the Virginia Statute for Religious Freedom in 1786.
Why is this seemingly obscure piece of Revolutionary-era legislation so vital? And why doesn’t the Christian Right want you to know anything about it?
The bill, authored by Thomas Jefferson and later pushed through the state legislature by then member of the House of Delegates, James Madison, is regarded as the root of how the framers of the Constitution approached matters of religion and government, and it was as revolutionary as the era in which it was written.
It not only disestablished the Anglican Church as the official state church, but it provided that no one can be compelled to attend any religious institution or to underwrite it with taxes; that individuals are free to believe as they will and that this “shall in no wise diminish, enlarge, or affect their civil capacities.”
As a practical matter, this meant that what we believe or don’t believe is not the concern of government and that we are all equal as citizens."
