I started transcribing the first one, I have around 10 pages done, here's the beginning in google translate english:
It seems to me to be of value to compile once in condensed form what the past time has worked out on the Jesus question. Not everyone has time to work through several thick volumes on the Jesus question. Also, many things are scattered in many individual writings and few have them together. Therefore, I have tried to put some essential passages from several books and writings next to each other, in order to give an overview, which, as I hope, presents the true state of affairs briefly and clearly. I take the title of truth fully upon myself, and I believe that I am not only acting quietly with every book, but also with this small text, in the spirit of Arthur Drews, whose life's work was especially dedicated to this struggle for truth. These remarks are intended to ensure that the work he and many others have done in this field does not fall into obscurity but, on the contrary, becomes better known. A clear path to the truth! The slogan of the German people must be no different. And this is especially true in religious matters and in the field of ideology.
About 100 years ago today, in scientific circles, one began to seriously deal with the question: Did Jesus live or not? One may be surprised that this has happened so late. However, the field of faith is originally far away from science. Science has little interest in this question of Jesus and whether it should be answered with "yes" or with "no". The one or the other answer can be equally* right for it. It knows also here as always only the one questioning: What has been true here? It is different for the church and the believing Christians. Whoever has grown up in childlike pious faith in the figure of Christ, whoever has never heard it otherwise than that Christ was born in Bethlehem in the year 1, lived in Palestine until about the age of 30, and then died for all mankind, will bring with him from the outset an emotional emphasis that makes the objective consideration of this question enormously difficult. Holiest emerges, Jesus has lived only in the imagination of an earlier time, but never bodily. Other Christians do not cling to their faith so much in filial fidelity, but their proud would find it hard to bear to convince themselves that daẞ they have only been groẞed in error. I and all others who stand up for the truth here are certainly far from wanting to hurt others. Nevertheless, it is necessary to stand up for the truth. And how many have already broken with the church today for completely different reasons! They say: Lies have short legs. This is often true. But it is also often not true. Superstition, for example, is also a kind of lie. In any case, it is a belief based on an untrue context. And yet a superstition can remain in a people for thousands of years. Yes, perhaps one or the other superstition will last as long as [people] are to be found at all, besides the other progress of culture. This, of course, passes over him, and its victory has nothing to do with the rest of his existence. The age of his belief, i.e. the temporal length, but also the spatial extension of its spreading, does not guarantee the content of the truth of his teaching. In any case, science wants other proofs. Science goes also in this case the way, which it always goes. It is the way of the conscientious research work; it should follow it unswervingly and incorruptibly.
For the science the question about Jesus lies embedded in the question and occidental man. Researching after it, the question of Jesus fell unintentionally into its hand. And how eagerly and thoroughly Christian organizations, in order to cover up the truth, destroyed in the past centuries most precious written material irretrievably and lamentably, nevertheless the threads of the truth began to string together to a fabric which in its basic features is already well overlookable.
I want to anticipate what has emerged from the research, summarized.
