"Nationalism, within proper limits, has the divine sanction; an imperialism that would, in the interest of one people, obliterate all lines of distinction is everywhere condemned as contrary to the divine will. Later prophecy raises its voice against the attempt at world-power, and that not only, as is sometimes assumed, because it threatens Israel, but for the far more principal reason, that the whole idea is pagan and immoral.
Now it is through maintaining the national diversities, as these express themselves in the difference of language, and are in turn upheld by this difference, that God prevents realization of the attempted scheme… [In this] was a positive intent that concerned the natural life of humanity. Under the providence of God each race or nation has a positive purpose to serve, fulfillment of which depends on relative seclusion from others."
