Who composed that Army of fine young Fellows that was then before my Eyes? There were among them, Roman Catholicks, English Episcopalians, Scotch and American Presbyterians, Methodists, Moravians, Anababtists, German Lutherans, German Calvinists Universalists, Arians, Priestleyans, Socinians, Independents, Congregationalists, Horse Protestants and House Protestants, Deists and Atheists; and "Protestans qui ne croyent rien ["Protestants who believe nothing"]." Very few however of several of these Species. Nevertheless all Educated in the general Principles of Christianity: and the general Principles of English and American Liberty.
Could my Answer be understood, by any candid Reader or Hearer, to recommend, to all the others, the general Principles, Institutions or Systems of Education of the Roman Catholicks? Or those of the Quakers? Or those of the Presbyterians? Or those of the Menonists? Or those of the Methodists? or those of the Moravians? Or those of the Universalists? or those of the Philosophers? No.
The general Principles, on which the Fathers Atchieved Independence, were the only Principles in which that beautiful Assembly of young Gentlemen could Unite, and these Principles only could be intended by them in their Address, or by me in my Answer. And what were these general Principles? I answer, the general Principles of Christianity, in which all those Sects were united: And the general Principles of English and American Liberty, in which all those young Men United, and which had United all Parties in America, in Majorities sufficient to assert and maintain her Independence.
Now I will avow, that I then believed, and now believe, that those general Principles of Christianity, are as eternal and immutable, as the Existence and Attributes of God; and that those Principles of Liberty, are as unalterable as human Nature and our terrestrial, mundane System. I could therefore safely say, consistently with all my then and present Information, that I believed they would never make Discoveries in contradiction to these general Principles. In favour of these general Principles in Phylosophy, Religion and Government, I could fill Sheets of quotations from Frederick of Prussia, from Hume, Gibbon, Bolingbroke, Reausseau and Voltaire, as well as Neuton and Locke: not to mention thousands of Divines and Philosophers of inferiour Fame.
