On "Christianity at the Crossroads" by Michael Kruger ****

This is a basic introduction to Christianity in the second century. As such, it's a good summary of the various issues that the second century presents for scholars to explore, written for lay people. I found the early parts a bit basic, retreading much that I've read elsewhere, covering the second-century society and culture, the basic practices and possible government forms, the manner of worship and meeting, and so on.

In chapter 4--about halfway through the book--is where Kruger really starts to get down to an argument that he explores more fully in another book: namely, he discusses how diverse the second century was in terms of belief and practice (as per much modern scholarship, based around Walter Bauer's thesis that there wasn't really any such thing as a unitary Christianity early on). Kruger doesn't believe that, so after exploring the differing non-mainstream Christian groups, he proceeds in chapter 5 to show how there actually was an orthodox Christian faith all the way back in the second century, one that stemmed from the first century. He argues this primarily by discussing "the rule of faith"--that is, the basic tenets that made Christians, in fact, Christians, into which the non-mainstream did not fit: the idea that Jesus Christ came in the flesh, died, and rose the third day; that he was God in the flesh; and so on.

Chapters 6 and 7 are where this book really shine, which is not surprising, given that the chapters cover topics that Kruger specializes in and has written several other works on: namely, the canonization of the scripture and the literary culture of the early church. Kruger goes into more detail on these subjects elsewhere, but these two chapters seem a very good and detailed summary of the issues and are what make this book worth the time spent reading it, even beyond just the basic introduction.
