If it be said that, in the case of the Church of Rome, there is not only a process of development, but an infallible developing power, and that this affords a guaranty, strong as the Divine promise itself, against that risk of error which is attendant on the ordinary methods of human teaching,--we answer, that this is a mere assumption, which requires to be proved, and that it cannot be proved in the face of the facts which attest the historical variations of the Romish Creed, as these are admitted and defended by Mr. Newman himself. For some of these variations are not consistent developments of the primitive articles of faith, but involve either a corruption or a contradiction of these very principles; and if her infallibility has not preserved her from the deification of saints, what security have we that it will preserve her from the deification of Nature? If it has already introduced a Christian Polytheism, why may it not issue in a Christian Pantheism? Admit the principle of development, and it may lead to the deification of man, as well as to the worship of Mary; to a sacred Calendar of Heroes, as well as of Saints.[98] It may terminate either in Infidelity or in Superstition, according to the mental temperament of the individual by whom it is adopted and applied. "An organ of investigation being introduced, which may be employed for any purpose indifferently, the tendency of such a theory of religious inquiry will just tell according to the spirit in which it acts. A skeptic will develop the principle into Infidelity, a believer into Superstition; but the principle itself remains accurately the same in both."[99] The connection between the theory of Ecclesiastical Development and the infidel theory of Progress has not escaped the notice of many acute and profound thinkers in recent times, nor the danger resulting from it to the most fundamental articles of faith. "Modern Spiritualists tell us that Christianity is a development, as the Papists also assert, and the New Testament is its first and rudimentary product; only, unhappily, as the development, it seems, may be things so different as Popery and Infidelity, we are as far as ever from any criterium as to which, out of the ten thousand possible developments, is the true; but it is a matter of the less consequence, since it will, on such reasoning, be _always something future_."[100] One of the most pernicious tenets of the Neologists beyond the Rhine is thus expressed by themselves: "Christianity renews itself in the human heart, and follows _the development_ of the human mind, and invests itself with new forms of thought and language, and adopts new systems of Church organization, to which it gives expression and life." ... "But are these teachers the _only_ destroyers of Faith and Morals? Are not _they_ also chargeable with precisely the same offence who command us to submit implicitly to the so-called divinely-inspired Spirit of '_one_ living Infallible
