" Every religion is constantly changing, and at any given time is the measure of the civilization attained by what Guizot described as the “just milieu” of those who profess it. Each religion is slowly, but certainly, modified in its dogma and practice by the gradual development of the people amongst whom it is professed. Each discovery destroys in whole or part some theretofore-cherished belief. No religion is suddenly rejected by any people; it is, rather, gradually outgrown.
