The other great problem, the origin of things, and the relation of God to the world, which is at the basis of religion, as the incarnation is at the basis of Christianity, has been less frequently handled. Originally discussed, like the latter, in controversy with the early unbelievers, it had been touched upon in the speculations of Averroes and Spinoza, in the materialism of French infidelity, and in the earlier systems of speculative philosophy in Germany itself. It was this problem which was attempted by Rothe. (40) Advancing beyond this first question, he has considered the scheme of Providence in the development of religion, and the theory of the Christian church in relation to political society. It is unnecessary here to explain his system: his mind is too original to admit of comparison without injustice; yet the speculations of our own Coleridge, who on philosophical principles makes the state to be the realisation of the church, will perhaps give some imperfect conception of the character of his attempts. This second school that we have been considering, though approximating extremely nearly to orthodoxy, and furnishing the works of most value in the modern theology, yet seeks to approach religion from the psychological or philosophical side. It speculates freely, and believes revelation because it finds it to coincide with the discoveries of free thought. But there is a third tendency, which believes revelation without professing to understand it; which rests on the revelation in scripture as an objective verity, and believes the Bible on the ground of evidence, without questioning its material.(850) The first germ of this reaction in favour of rigid orthodoxy was observable in the feeling aroused by the theses of Harms, in 1817, already named, on occasion of the celebration of the tricentenary of the Reformation; but it was quickened by the attempts, initiated by the Prussian king, between the years 1821 and 1830, to unite the Lutheran and Calvinistic branches of the Protestant church.(851)
