We will now in addition deal only briefly with religion, since the latter stand further away from material life and seems to be most alien to it. religion arose in very primitive times from erroneous, primitive conceptions of men about their own nature and external nature surrounding them. Every ideology, however, once it has arisen, develops in connection with the given concept-material, and develops this material further; otherwise, it would not be an ideology, that is, occupation with thoughts as with independent entities, developing independently and subject only to their own laws. In the last analysis, the material life conditions of the persons inside whose heads this thought process goes on determine the course of the process, which of necessity remains unknown to these persons, for otherwise there would be an end to all ideology. These original religious notions, therefore, which in the main are common to each group of kindred peoples, develop, after the group separates, in a manner peculiar to each people, according to the conditions of life falling to their lot. For a number of groups of peoples, and particularly for the Aryans (so-called Indo-Europeans) this process has been shown in detail by comparative mythology. The gods thus fashioned within each people were national gods, whose domain extended no farther than the national territory which they were to protect; on the other side of its boundaries, other gods held undisputed sway. They could continue to exist, in imagination, only as long as the nation existed; they fell with its fall. The Roman world empire, the economic conditions of whose origin we do not need to examine here, brought about this downfall of the old nationalities. The old national gods decayed, even those of the Romans, which also were patterned to suit only the narrow confines of the city of Rome. The need to complement the world empire by means of a world religion was clearly revealed in the attempts made to recognize all foreign gods that were the least bit respectable and provide altars for them in Rome alongside the native gods. But a new world religion is not to be made in this fashion, by imperial decree. The new world religion, Christianity, had already quietly come into being, out of a mixture of generalized Oriental, particularly Jewish, theology, and vulgarized Greek, particularly Stoic, philosophy. What it originally looked like has to be first laboriously discovered, since its official form, as it has been handed down to us, is merely that in which it became the state religion to which purpose it was adapted by the Council of Nicaea. The fact that already after 250 years it became the state religion suffices to show that it was the religion in correspondence with the conditions of the time. In the Middle Ages, in the same measure as feudalism developed, Christianity grew into the religious counterpart to it, with a corresponding feudal hierarchy.
And when the burghers began to thrive, there developed, in opposition to feudal Catholicism, the Protestant heresy, which first appeared in Southern France among the Albigenses [12], at the time the cities there reached the highest point of their florescence. The Middle Ages had attached to theology all the other forms of ideology -- philosophy, politics, jurisprudence -- and made them subdivision of theology. It thereby constrained every social and political movement to take on a theological form. The sentiments of the masses were fed with religion to the exclusion of all else; it was therefore necessary to put forward their own interests in a religious guise in order to produce a great tempest. And just as the burghers from the beginning brought into being an appendage of propertyless urban plebeians, day laborers and servants of all kinds, belonging to no recognized social estate, precursors of the later proletariat, so likewise heresy soon became divided into a burgher-moderate heresy and a plebeian-revolutionary one, the latter an abomination to the burgher heretics themselves.
The ineradicability of the Protestant heresy corresponded to the invincibility of the rising burghers. When these burghers had become sufficiently strengthened, their struggle against the feudal nobility, which till then had been predominantly local, began to assume national dimensions. The first great action occurred in Germany -- the so-called reformation. The burghers were neither powerful enough nor sufficiently developed to be able to unite under their banner the remaining rebellious estates -- the plebeians of the towns, the lower nobility, and the peasants on the land.
At first, the nobles were defeated; the peasants rose in a revolt which formed the peak of the whole revolutionary struggle; the cities left them in the lurch, and thus the revolution succumbed to the armies of the secular princes who reaped the whole profit. Thenceforward, Germany disappears for three centuries from the ranks of countries playing an independent active part in history. But, beside the German Luther appeared the Frenchman Calvin. With true French acuity, he put the bourgeois character of the Reformation in the forefront, republicanized and democratized the Church.
