U.S. Supreme Court Justice, and Harvard's first Dane Prof. of Law, Joseph Story wrote the definitive law School text Commentaries on the Constitution, in use until the 1930's. His 1834 grade school version "Constitutional Classbook" has this dedication:
“To The Schoolmasters of the United States, Whose Meritorious, Though Ill-Requited Labors Have Conferred Lasting Benefits On Their Country, By Sound Learning, Pure Patriotism,
And Christian Piety This Work Is Respectfully Dedicated,
By Their Grateful Friend and Servant.”
From his 1829 Harvard address:
"VALUE AND IMPORTANCE OF LEGAL STUDIES".
Quote: "One of the beautiful boasts of our municipal jurisprudence is, that Christianity is a part of the common law, from which it seeks the sanction of its rights, and by which it endeavours to regulate its doctrines."
"With us, indeed, who form a part of the Christian community of nations, the law of nature has a higher sanction as it stands supported and illustrated by revelation.
Christianity, while with many minds it acquires authority from its coincidences with the law of nature..."
It is clear, from America's leading jurist, Christianity is key to public education...and the SUCCESSFUL application of Constitutional law.
