“Protestantism is more in conformity with the Nordic spirit than is Roman Catholicism. The Nordic's strong sense of independence, his desire for an individual judgement, and for personal responsibility, rise up in revolt against the authoritarian standpoint of Catholicism; and, furthermore, the Catholic religious service, with its appeal to the senses and emotions, is less congenial to the rationalist spirit of the Nordic man than is the comparative sobriety of the Protestant religious service.”

Human Hereditary, Eugen Fischer, et al., 1931

“In the main two forms of Catholicism are religions of authority, of convention, of ritual; they are preeminently social in their rites and celebrations. Only the Protestant reads his Bible in his closet and communes alone with God. Only the Protestant Church has split into a thousand peculiar sects...Protestantism is the only one of the three forms which permits and even encourages individualism and independence.”
