Is the Bible Really Unique?
Format: Kindle
Oswalt takes up the question of the uniqueness of the Christian Bible by focusing on the Old Testament (which is also the holy book of the Jews) and its similarities and differences to the myths of the periods in which it was put together. His comparison and contrast make for very interesting reading. He allows the two world views to stand alone, allowing the reader to understand his conclusions without forcing him/her to agree with the author. In reading this book, I also began to notice some very interesting parallels between the ancient worldview of "continuity" (versus the biblical view that Oswalt calls "transcendence") and some modern views being espoused in the Western world. Definitely worth a read whether or not you agree with him. It will help broaden your view both of your view and of the other side's view.

Good Core Content but I won't read it again
Format: Kindle
This book makes a strong stand for the position that the Bible does not fit within the genre of myth. That is the positive aspects of this work. However, this book at times seems somewhat philosophical, it can be hard to follow the author's logic, and it does not adequately cover one of the most fundamental questions the author poses. For example, the question of whether the theology of the Bible should receive special credence if the historical basis it rests on is found to be incorrect is asked, but the answer given is short and does not fully interact with the question which I found to be very disappointing.
