A good introductory level work to the book of Genesis. In this book, Enns and Byas talk about the overarching theme of the book of Genesis as a whole; it's the story of Israel. Enns and Byas propose that Genesis was written in the exilic period or post-exhilic period (i.e when Israel was in Babylonian Captivity) with the purpose of showing them how, even though their ancestors routinely messed up, God was still faithful to them and carried on with the plan of building the nation anyway. The moral flaws of Abraham, Isaac, Jacob, and Joseph are highlighted in Genesis, but so is their faithfulness, and the author has shown that God was good to his promise to bless those who bless Israel and curse those who curse Israel. Moreover, what the author is doing in some of the earliest parts is subverting Babylonian theology. For example, Genesis 1 exhaults Yahweh as the supreme Creator of all and ascribes to him some things ascribed to the Babylonian God, Marduk. And goes one step further. For example, Marduk had to overcome a chaos dragon named Tiamut before he created the heavens and earth. This was not so with Yahweh. Yahweh simply showed up over "The Deep" (i.e Tiamut's place of residence) and the chaos dragon was nowhere to be found. God just showed up and got to work. No battle needed (of course, later books such as Job and the Psalms do depict God going to war with a sea dragon of chaos, but Genesis depicts such a fight as God showing up to the ring and his opponent being too scared to show his face). He just shows up and starts bringing functions to the universe.
Given his book "The Evolution Of Adam", which left a bad taste in my mouth, I didn't expect to agree with Enns as much as I did. I expected to find myself disagreeing with about half of it, but I read the book to glean what I thought Enns probably would get more or less right. After all, nobody is 100% wrong about everything they write, and you can even learn from people you disagree with. However, to my surprise, Enns' book was surprisingly informative.
It wasn't quite as in depth as I would have liked, but it wasn't designed to do that, and the authors admit up front that this was going to just be a broad overview of the book. Now, I said that "Enns and Byas propose that Genesis was written in the exilic period or post-exhilic period". This is true. They adhere to what is known in layman's terms as "The Documentary Hypothesis" or, to use the more scholarly term, JEDP. But while I disagree that Moses had NO hand whatsoever in the composition of the Torah, I'm willing to concede that someone else might have written Genesis, and especially the parts near the end of the Torah that record Moses' unsurpassing humility and his death. I would hold to what Michael Heiser calls "A Mosaic Core" view. Maybe all Moses wrote down were the laws and regulations. Maybe he recorded none of the historical narrative at all. Or maybe he wrote only two of the five books. But Moses had to have SOME impact on the shaping of the Torah. Why? Because Jesus said so! Everytime Jesus talks about what the Torah says, He will talk about it as Moses being the one who wrote what is in the scriptures.
