John Adams - “The Christian religion, as I understand it, is the brightest of the glory and the express portrait of the character of the eternal, self-existent, independent, benevolent, all-powerful, and all-merciful Creator, Preserver and Father of the Universe, the first good, the first perfect, and the first fair.
