This permanent necessity of Religious Institutions is primarily a need for men to teach and exemplify, not simply Natural, This-World Morality, but a Supernatural, Other-World Ethic; and not simply that abstraction, Religion in General or a Religious Hypothesis, but that rich concretion, this or that Historical Religion. In proportion as such an Historical Religion is deep and delicate, it will doubtless contain affinities with all that is wholesome and real within the other extant historical religions. Nevertheless, all religions are effectual through their special developments, where these developments remain true at all. As well deprive a flower of its 'mere details' of pistil, stamen, pollen, or an insect of its 'superfluous' antennae, as simplify any Historical Religion down to the sorry stump labelled 'the religion of every honest man'. We shall escape all bigotry, without lapsing into such most unjust indifferentism, if we vigorously hold and unceasingly apply the doctrine of such a Church theologian as Juan de Lugo. De Lugo (A.D. 1583-1660), Spaniard, post-Reformation Roman Catholic, Jesuit, Theological Professor, and a Cardinal writing in Rome under the eyes of Pope Urban VIII, teaches that the members of the various Christian sects, of the Jewish and Mohammedan communions, and of the heathen religions and philosophical schools, who achieve their salvation, do so, ordinarily, simply through the aid afforded by God's grace to their good faith in its instinctive concentration upon, and in its practice of, those elements in their respective community's worship and teaching, which are true and good and originally revealed by God.[51] Thus we escape all undue individualism and all unjust equalization of the (very variously valuable) religious and philosophical bodies; and yet we clearly hold the profound importance of the single soul's good faith and religious instinct, and of the worship or school, be they ever so elementary and imperfect, which environ such a soul.
