So when Hooker says most truly: 'Our belief in the Trinity, the co-eternity of the Son of God with his Father, the proceeding of the Spirit from the Father and the Son, with other principal points the necessity whereof is by none denied, are notwithstanding in Scripture nowhere to be found by express literal mention, only deduced they are out of Scripture by collection;'--when Hooker thus points, out, what is undoubtedly the truth, that these Church-doctrines are developments, we may add this other truth equally undoubted,--that being _philosophical_ developments, they are developments of a kind which the Church has never yet had the right conditions for making adequately, any more than it has had the conditions for developing out of what is said in the Book of Genesis a true philosophy of nature, or out of what is said in the Book of Daniel, a true philosophy of history. It matters nothing whether the scientific truth was there, and the problem was to extract it; or not there, and the problem was to understand why it was not there, and the relation borne by what was there to the scientific truth. The Church had no means of solving either the one problem or the other. And this from no fault at all of the Church, but for the same reason that she was unfitted to solve a difficulty in Aristotle's _Physics_ or Plato's _Timæus_, and to determine the historical value of Herodotus or Livy; simply from the natural operation of the law of development, which for success in philosophy and criticism requires certain conditions, which in the early and mediæval Church were not to be found. And when the movement of philosophy and criticism came with the Renascence, this movement was almost entirely outside the Churches, whether Catholic or Protestant, and not inside them. It worked in men like Descartes and Bacon, and not in men like Luther and Calvin; so that the doctrine of these two eminent personages, Luther and Calvin, so far as it was a philosophical and critical development from Scripture, had no more likelihood of being an adequate development than the doctrine of the Council of Trent. And so it has gone on to this day. Philosophy and criticism have become a great power in the world, and inevitably tend to alter and develop Church-doctrine, so far as this doctrine is, as to a great extent it is, philosophical and critical. Yet the seat of the developing force is not in the Church itself, but elsewhere; its influences filter strugglingly into the Church, and the Church slowly absorbs and incorporates them. And whatever hinders their filtering in and becoming incorporated, hinders truth and the natural progress of things.
