“Suns are extinguished or become corrupted, planets perish and scatter across the wastes of the sky; other suns are kindled, new planets formed to make their revolutions or describe new orbits, and man, an infinitely minute part of a globe which itself is only an imperceptible point in the immense whole, believes that the universe is made for himself.”

Context: There are several sorts of religions, not only in different parts of the island, but even in every town; some worshipping the sun, others the moon or one of the planets. Some worship such men as have been eminent in former times for virtue or glory, not only as ordinary deities, but as the supreme god. Yet the greater and wiser sort of them worship none of these, but adore one eternal, invisible, infinite, and incomprehensible Deity; as a Being that is far above all our apprehensions, that is spread over the whole universe, not by His bulk, but by His power and virtue; Him they call the Father of All, and acknowledge that the beginnings, the increase, the progress, the vicissitudes, and the end of all things come only from Him; nor do they offer divine honours to any but to Him alone. And, indeed, though they differ concerning other things, yet all agree in this: that they think there is one Supreme Being that made and governs the world, whom they call, in the language of their country, Mithras. They differ in this: that one thinks the god whom he worships is this Supreme Being, and another thinks that his idol is that god; but they all agree in one principle, that whoever is this Supreme Being, He is also that great essence to whose glory and majesty all honours are ascribed by the consent of all nations.
