What is the relation of modern Christianity to this vast and unparalleled progress of science? In the first place, the deep gulf between its two great branches, conservative Romanism and progressive Protestantism, has naturally widened. The ultramontane clergy (and we must associate with them the orthodox "evangelical alliance") had naturally to offer a strenuous opposition to this rapid advance of the emancipated mind; they continued unmoved in their rigid literal belief, demanding the unconditional surrender of reason to dogma. Liberal Protestantism, on the other hand, took refuge in a kind of monistic pantheism, and sought a means of reconciling two contradictory principles. It endeavored to combine the unavoidable recognition of the established laws of nature, and the philosophic conclusions that followed from them, with a purified form of religion, in which scarcely anything remained of the distinctive teaching of faith. There were many attempts at compromise to be found between the two extremes; but the conviction rapidly spread that dogmatic Christianity had lost every foundation, and that only its valuable ethical contents should be saved for the new monistic religion of the twentieth century. As, however, the existing external forms of the dominant Christian religion remained unaltered, and as, in spite of a progressive political development, they are more intimately than ever connected with the practical needs of the State, there has arisen that widespread religious profession in educated spheres which we can only call "pseudo-Christianity"--at the bottom it is a "religious lie" of the worst character. The great dangers which attend this conflict between sincere conviction and the hypocritical profession of modern pseudo-Christians are admirably described in Max Nordau's interesting work on _The Conventional Lies of Civilization_.
