“The American Constitution does resemble the Spanish Inquisition in this: that it is founded on a creed. America is the only nation in the world that is founded on a creed. That creed is set forth with dogmatic and even theological lucidity in the Declaration of Independence; perhaps the only piece of practical politics that is also theoretical politics and also great literature. It enunciates that all men are equal in their claim to justice, that governments exist to give them that justice, and that their authority is for that reason just. It certainly does condemn anarchism, and it does also by inference condemn atheism, since it clearly names the Creator as the ultimate authority from whom these equal rights are derived. Nobody expects a modern political system to proceed logically in the application of such dogmas, and in the matter of God and Government it is naturally God whose claim is taken more lightly. The point is that there is a creed, if not about divine, at least about human things.

“Now a creed is at once the broadest and the narrowest thing in the world. In its nature it is as broad as its scheme for a brotherhood of all men. In its nature it is limited by its definition of the nature of all men. This was true of the Christian Church, which was truly said to exclude neither Jew nor Greek, but which did definitely substitute something else for Jewish religion or Greek philosophy. It was truly said to be a net drawing in of all kinds; but a net of a certain pattern, the pattern of Peter the Fisherman. And this is true even of the most disastrous distortions or degradations of that creed; and true among others of the Spanish Inquisition. It may have been narrow touching theology, it could not confess to being narrow about nationality or ethnology. The Spanish Inquisition might be admittedly Inquisitorial; but the Spanish Inquisition could not be merely Spanish. Such a Spaniard, even when he was narrower than his own creed, had to be broader than his own empire. He might burn a philosopher because he was heterodox; but he must accept a barbarian because he was orthodox. And we see, even in modern times, that the same Church which is blamed for making sages heretics is also blamed for making savages priests. Now in a much vaguer and more evolutionary fashion, there is something of the same idea at the back of the great American experiment; the experiment of a democracy of diverse races which has been compared to a melting-pot. But even that metaphor implies that the pot itself is of a certain shape and a certain substance; a pretty solid substance. The melting-pot must not melt. The original shape was traced on the lines of Jeffersonian democracy; and it will remain in that shape until it becomes shapeless. America invites all men to become citizens; but it implies the dogma that there is such a thing as citizenship. Only, so far as its primary ideal is concerned, America’s exclusiveness is religious because it is not racial. The missionary can condemn a cannibal, precisely because he cannot condemn a Sandwich Islander. And in something of the same spirit the American may exclude a terrorist, precisely because he cannot exclude an Arab.”
