“I suspect that some of you would say ‘A civilized nation is one that has railways, modern industry, organized army, tank, aircraft, etc., and an uncivilized nation is one that does not possess such things.’ Or you would say that a civilized nation is one whose cities … have wide and paved streets, with multi-storey buildings, and so on.’ Civilized nations, of course, do have such things, but I submit that these are products of civilization, not its essence. The essence of civilization is that people are mature, and the clearest sign of their maturity is that they observe the law.”

1910s, Address to the Knights of Columbus (1915)
Context: There must be not merely preparedness in things material; there must be preparedness in soul and mind. To prepare a great army and navy without preparing a proper national spirit would avail nothing. And if there is not only a proper national spirit, but proper national intelligence, we shall realize that even from the standpoint of the army and navy some civil preparedness is indispensable. For example, a plan for national defense which does not include the most far-reaching use and cooperation of our railroads must prove largely futile. These railroads are organized in time of peace. But we must have the most carefully thought out organization from the national and centralized standpoint in order to use them in time of war. This means first that those in charge of them from the highest to the lowest must understand their duty in time of war, must be permeated with the spirit of genuine patriotism; and second, that they and we shall understand that efficiency is as essential as patriotism; one is useless without the other.

The Hireling Ministry, None of Christ's (1652)
Context: The civil state of the nations, being merely and essentially civil, cannot (Christianly) be called "Christian states," after the pattern of that holy and typical land of Canaan, which I have proved at large in the Bloudy Tenent to be a nonesuch and an unparalleled figure of the spiritual state of the church of Christ Jesus, dispersed yet gathered to Him in all nations.
The civil sword (therefore) cannot (rightfully) act either in restraining the souls of the people from worship, etc., or in constraining them to worship, considering that there is not a tittle in the New Testament of Christ Jesus that commits the forming or reforming of His spouse and church to the civil and worldly powers...

Letter to François Adriaan van der Kemp (16 February 1809)
1800s
Context: I will insist that the Hebrews have done more to civilize men than any other nation. If I were an atheist, and believed in blind eternal fate, I should still believe that fate had ordained the Jews to be the most essential instrument for civilizing the nations. If I were an atheist of the other sect, who believe or pretend to believe that all is ordered by chance, I should believe that chance had ordered the Jews to preserve and propagate to all mankind the doctrine of a supreme, intelligent, wise, almighty sovereign of the universe, which I believe to be the great essential principle of all morality, and consequently of all civilization.
