I haven't read this book, but I've noticed the same tendencies in Ehrmam. They come out especially forcefully in his debate with Craig. But why should he stop writing these books? -- they're selling like bottes of water at an Iron Man competition in Death Valley. For those interested, here's my argument on "How Confucius Proves Jesus;" (partly from my book Why the Jesus Seminar can't find Jesus, which beats up on some of Bart's comrades in arms) it takes a rather different approach from the norm: http://christthetao.blogspot.com/2011/01/how-confucius-proves-jesus.html
Thanks, David. I appreciate your interactions with John Loftus.
