And thirdly, if the germs were really deposited by Christ and His Apostles, they would have developed in a _somewhat_ similar manner in all parts of Christendom. Different surroundings will account for some variety of development, but not for absolute difference in kind. The germ respecting communion with the Church of Rome, if there was one, developed in the East, where all germs were in the first instance planted, into the doctrine that no such communion was necessary.[111] Therefore, from the Roman point of view, it is necessary to maintain that the development of Christian doctrine involves, not merely the better comprehension of the contents of doctrines, and the expansion of seeds and germs of truth, but the admission of actual supplements and additions, derived from new revelations of fresh items of truth. As the Jesuit Father Harper said, in his reply to Dr. Pusey's _Eirenicon_, "Christ grew in wisdom daily. So does the Church, not in mere appearance, but of truth. Her creed, therefore, can never shrink back to the dimensions of the past, but must ever enlarge with the onward future." Hence the necessity for the doctrine of Infallibility. For Roman developments are not the only ones. The Eastern Churches have theirs; Protestant Churches have theirs; and outside these there are other developments, both non-Christian and anti-Christian. Unless there is some authority which can say, "Our developments are Divinely inspired and necessary, while all others are superfluous or wrong," the doctrine of Development may be used with as much force against Rome as for her. Consequently, we find the author of the Essay using the theory of Development as an argument for that of the Infallibility. "If the Christian doctrine, as originally taught, admits of true and important developments, ... this is a strong antecedent argument in favour of a provision in the Dispensation for putting a seal of authority upon those developments.... If certain large developments of it are true, they must surely be accredited as true" (pp. 117-19).
