As Origens do Cristianismo Segundo Bauer e Engels

Um artigo escrito por Engels em 1882 após a morte de Bauer. Nele  Engels resume as idéias do falecido sobre o Cristianismo e as completa:

In all previous religions, ritual had been the main thing. Only by taking part in the sacrifices and processions, and in the Orient by observing the most detailed diet and cleanliness precepts, could one show to what religion one belonged. While Rome and Greece were tolerant in the last respect, there was in the Orient a rage for religious prohibitions that contributed no little to the final downfall. People of two different religions (Egyptians, Persians, Jews, Chaldeans) could not eat or drink together, perform any every-day act together, or hardly speak to each other. It was largely due to this segregation of man from man that the Orient collapsed. Christianity knew no distinctive ceremonies, not even the sacrifices and processions of the classic world. By thus rejecting all national religions and their common ceremonies, and addressing itself to all peoples without distinction, it became the first possible world religion. Judaism, too, with its new universal god, had made a start on the way to becoming a universal religion; but the children of Israel always remained an aristocracy among the believers and the circumcised, and Christianity itself had to get rid of the notion of the superiority of the Jewish Christians (still dominant in the so-called Book of Revelation of John) before it could really become a universal religion. Islam, itself, on the other hand, by preserving its specifically Oriental ritual, limited the area of its propagation to the Orient and North Africa, conquered and populated anew by Arab Bedouins; here it could become the dominating religion, but not in the West.

Secondly, Christianity struck a chord that was bound to echo in countless hearts. To all complaints about the wickedness of the times and the general material and moral distress, Christian consciousness of sin answered: It is so and it cannot be otherwise; thou art in blame, ye are all to blame for the corruption of the world, thine and your own internal corruption! And where was the man who could deny it? Mea culpa! The admission of each one's share in the responsibility for the general unhappiness was irrefutable and was made the precondition for the spiritual salvation which Christianity at the same time announced. And this spiritual salvation was so instituted that it could be easily understood by members of every old religious community. The idea of atonement to placate the offended deity was current in all the old religions; how could the idea of self-sacrifice of the mediator atoning once for all for the sins of humanity not easily find ground there? Christianity, therefore, clearly expressed the universal feeling that men themselves are guilty of the general corruption as the consciousness of sin of each one; at the same time, it provided, in the death-sacrifice of his judge, a form of the universally longed-for internal salvation from the corrupt world, the consolation of consciousness; it thus again proved its capacity to become a world religion and, indeed, a religion which suited the world as it then was.

So it happened that, among the thousands of prophets and preachers in the desert that filled that period of countless religious novations, the founders of Christianity alone met with success. Not only Palestine, but the entire Orient swarmed with such founders of religions, and between them there raged what can be called a Darwinian struggle for ideological existence. Thanks mainly to the elements mentioned above, Christianity won the day. How it gradually developed its character of world religion by natural selection in the struggle of sects against one another and against the pagan world is taught in detail by the history of the Church in the first three centuries.
