Such quotations as these, which might be multiplied indefinitely, show clearly enough that true, religious Christianity has within it no principle of scientific and material culture, no motive to it. The practical end and object of Christians is solely heaven, i.e., the realised salvation of the soul. The theoretical end and object of Christians is solely God, as the being identical with the salvation of the soul. He who knows God knows all things; and as God is infinitely more than the world, so theology is infinitely more than the knowledge of the world. Theology makes happy, for its object is personified happiness. Infelix homo, qui scit illa omnia (created things) te autem nescit, Beatus autem qui te scit, etiam si illa nesciat.--Augustin (Confess. l. v. c. 4). Who then would, who could exchange the blessed Divine Being for the unblessed worthless things of this world? It is true that God reveals himself in Nature, but only vaguely, dimly, only in his most general attributes; himself, his true personal nature, he reveals only in religion, in Christianity. The knowledge of God through Nature is heathenism; the knowledge of God through himself, through Christ, in whom dwelt the fulness of the Godhead bodily, is Christianity. What interest, therefore, should Christians have in occupying themselves with material, natural things? Occupation with Nature, culture in general, presupposes, or, at least, infallibly produces, a heathenish, mundane, anti-theological, anti-supranaturalistic sentiment and belief. Hence the culture of modern Christian nations is so little to be derived from Christianity, that it is only to be explained by the negation of Christianity, a negation which certainly was, in the first instance, only practical. It is indeed necessary to distinguish between what the Christians were as Christians and what they were as heathens, as natural men, and thus between that which they have said and done in agreement, and that which they have said and done in contradiction with their faith.
