The predictable controversy surrounding the litigation, which involves similar but distinct mandatory Ten Commandments display laws arising out of Texas and Louisiana, is revealing as to just how far America has fallen from its Founders’ vision. Jeff Landry signed into law a bill requiring that the Ten Commandments be displayed in every public school classroom — from kindergarten through the university level — throughout the state. From the Founders’ perspective, the Establishment Clause was a necessary federalism provision for a fledgling, religiously pluralistic republic. Instead, the notion of a “wall of separation between Church & State” has its origins in a pithy 1802 letter Thomas Jefferson sent to the Danbury Baptist Association in Connecticut. The United States was founded on ecumenical biblical principles, and the Ten Commandments — the wellspring of so much of Western morality — embody that ecumenicism.
