In this issue of Areopagus Journal, we respond to a longstanding attack on the inspiration, infallibility, and authority of the Bible that questions biblical claims regarding its authorship. Our first article by Prof. Daniel Block responds to the Weelhausen documentary Hypothesis theory held by most critical scholars. The second article written by Prof. Richard Schultz responds to the claim of liberal scholars that there were at least two, if not three or more, authors of the Book of Isaiah, compiled later into one book, and not given a specific prophetic authority. Schultz addresses the growing evidence that points to one book and Isaiah as its single prophetic author. The third article written by Prof. Matt Aernie addresses the liberal position that the four traditional Evangelists could not have been the writes of the four Gospels. Aernie responds with external and internal evidences to make an adequate positive case for the traditional authorship of the Gospels.The last article is by Prof. Terry Wilder who responds to skeptics that the New Testament letters are forgeries by demonstrating how the canonical letters pass the tests that the false epistles fail. He also demonstrates the internal evidence, integrity and historical acceptability of the New Testament epistles.
