In the early 1900's. a twelve volume work on theology titled The Fundamentals was published. This massive work, in my most humble of opinions, is just as relevant today if not more so with the ever increasing attacks on the faith of Christians--and that's just from folks inside the church. I wanted to publish some excerpts from this work that I think will be greatly encouraging to you.
During the last quarter of a century an influential school of critics has deluged the world with articles and volumes attempting to prove that the Pentateuch did not originate during the time of Moses, and that most of the laws attributed to him did not come into existence until several centuries after his death, and many of them not till the time of Ezekiel. By these critics the patriarchs are relegated to the realm of myth or dim legend and the history of the Pentateuch generally is discredited. In answering these destructive contentions and defending the history which they discredit we can do no better than to give a brief summary of the arguments of Mr. Harold M. Wiener, a young orthodox Jew, who is both a well established barrister in London, and a scholar of the widest attainments. What he has written upon the subject during the last ten years would fill a thousand octavo pages; while our condensation must be limited to less than twenty. In approaching the subject it comes in place to consider.
The Mosaic authorship of the Pentateuch has until very recent times been accepted without question by both Jews and Christians. Such acceptance, coming down to us in unbroken line from the earliest times of which we have any information, gives it the support of what is called general consent, which, while perhaps not absolutely conclusive, compels those who would discredit it to produce incontrovertible opposing evidence. But the evidence which the critics produce in this case is wholly circumstantial, consisting of inferences derived from a literary analysis of the documents and from the application of a discredited evolutionary theory concerning the development of human institutions.
