Clearly, prominent Founders saw the Ten Commandments and religious codes in general – as the foundation of American civil law. In fact, the belief was clear that public adherence to religious principles was the greatest source of security for civil government:
The Holy Scriptures can alone secure to society, order and peace, and to our courts of justice and constitutions of government, purity, stability, and usefulness. In vain, without the Bible, we increase penal laws and draw entrenchments protections around our institutions. James McHenry, Signer of the Constitution
Men, in a word, must necessarily be controlled either by a power within them or by a power without them; either by the Word of God or by the strong arm of man; either by the Bible or by the bayonet. Robert Winthrop, Speaker of the U.S. House
Human legislators can undertake only to prescribe the actions of men; they acknowledge their inability to govern and direct the sentiments of the heart. It is one of the greatest marks of Divine favor bestowed upon the children of Israel that the legislator God gave those rules not only of action, but for the government of the heart. John Quincy Adams
We seek to prevent in some measure the extension of the penal code by inspiring a salutary and conservative principle of virtue and of knowledge in an early age. By general instruction we seek, as far as possible, to purify the whole moral atmosphere and to turn the strong current of feeling and opinion, as well as the censures of the law and the denunciations of religion, against immorality and crime. Daniel Webster
Had I a voice that could be heard from New Hampshire to Georgia, it should be exerted in urging the necessity of disseminating virtue and knowledge among our citizens. On this subject, the policy of the eastern States is well worth of imitation. The wise people of that extremity of the union never form a new township without making arrangements that secure to its inhabitants the instruction of youth and the public preaching of the gospel. Hence their children are early taught to know their rights and to respect themselves. They grow up good members of society and staunch defenders of their country’s cause. David Ramsay, Revolutionary Surgeon; Member of the Continental Congress
David Barton - How can I have my deepest and most profound needs met?" There is some overlap there. There are also some unique things that are different for the believer and the nonbeliever but there are many things that bleed together.
