Response: Let’s be 100 percent honest! Probably everyone or virtually everyone has some baggage and bias, unless they are a Martian.
Being, human, I too, have limitations. And, as I have discussed earlier, I was challenged to research the topic. Of course, I wanted the “Jewish” side to win. However, my methodology at first, was to explore virtually exclusively the arguments in support of Jesus’s resurrection. The best “stuff”, at first that I found was by William Lane Craig and Josh McDowell. Afterwards, I explored texts specifically categorized as apologetics [BT1095-1100 Congress Library system] followed by Dogmatics and Systematic Theology [in general BT 65-100]. I also explored commentaries to the Gospels [usually very disappointing] and Introduction to the New Testament… After making my list of pro arguments it was then time to find rebuttals. Very little material exists that is/was written by Jews, REALLY. A healthy amount of material by atheists, agnostics, apostates [X-Christians, etc] exists, but often they repeat the same old and tired rebuttals. About ten years into the project, R. Moshe Shulman provided the suggestion that I go through the Christian Bible chronologically and employ Speculations and Contradictions. I re-wrote, deleted, added, etc material and eventually came out with my text. So, although I am biased, I believe that my research was intellectually honest. And, unlike most, if not all Christian apologists, I try to give them a real voice in my text. Just look at my bibliography. However, Volume 2 will specifically interact with Christian Apologists, at least that is my plan.
The ideal is to examine the topic starting tabula rasa. The comment by E.P Sanders (2000, 39) cited in my Preface (xlv) is an ideal but not always practical. See p. xlv…Also, see the comment of Taussig (2004, 249), my xlvii. In so far as burden of proof, see 14-24. Here, I present both sides of the aisle.
Finally, if you examine my home page, you will see I list a healthy selection of books: PRO and CON, about the topic. Be honest, how many Christian apologists list the best books of their opponents and place it/them on their homepage?
