Thomas McKean and George Read, both signers of the Declaration of Independence and members of the Continental Congress, along with Richard Bassett, a signer of the Constitution of the United States, participated in the writing of the original Constitution of the State of Delaware, which stated:
Article XXII. Every person who shall be chosen a member of either house, or appointed to any office or place of trust … shall … make and subscribe the following declaration, to wit: “I, _____, do profess faith in God the Father, and in Jesus Christ His only Son, and in the Holy Ghost, one God, blessed for evermore; and I do acknowledge the holy scriptures of the Old and New Testaments to be given by divine inspiration.”
Benjamin Rush, signer of the Declaration of Independence, member of the Continental Congress, president of Society for Promoting Abolition of Slavery, founder of Philadelphia Bible Society, wrote in his book Essays, Literary, Moral, and Philosophical:
I know there is an objection among many people to teaching children doctrines of any kind, because they are liable to be controverted. But let us not be wiser than our Maker.
If moral precepts alone could have reformed mankind, the mission of the Son of God into all the world would have been unnecessary. The perfect morality of the Gospel rests upon the doctrine which, though often controverted has never been refuted: I mean the vicarious life and death of the Son of God.
In the same book, Rush also explained:
Christianity is the only true and perfect religion, and that in proportion as mankind adopts its principles and obeys its precepts, they will be wise and happy.
In contemplating the political institutions of the United States, I lament that we waste so much time and money in punishing crimes and take so little pains to prevent them. We profess to be republicans, and yet we neglect the only means of establishing and perpetuating our republican forms of government, that is, the universal education of our youth in the principles of Christianity by the means of the Bible.
For this Divine book, above all others, favors that equality among mankind, that respect for just laws, and those sober and frugal virtues, which constitute the soul of republicanism.
John Adams, signer of the Declaration of Independence, member of the Continental Congress, and second President of the United States, wrote:
Suppose a nation in some distant Region should take the Bible for their only law Book, and every member should regulate his conduct by the precepts there exhibited! Every member would be obliged in conscience, to temperance, frugality, and industry; to justice, kindness, and charity towards his fellow men; and to piety, love, and reverence toward Almighty God … What a Eutopia, what a Paradise would this region be.
