Adam’s race, as it spread across the earth, would have formed distinct civil communities—each being culturally particular. The nation, therefore, is natural to man as man, and the matured earth would be a multiplicity of nations. I now turn to discuss how the fall and redeeming grace affect the nature of man and his social relations.
You have ZERO evidence of this. Any notion of a “Christian Nation” is completely contrary to what Christ came to bring.
