A Christian seminarian (at a Southern Baptist seminary--a conservative inerrantist institution), named Chris Petersen, has composed an article titled, "The Triumph of the Gospel of John in American Evangelicalism," that includes some questions I too struggled with before I left the fold.
The questions this student raises are not new. They arise whenever students and scholars of the Bible compare the three synoptic Gospels with the Gospel of John. For instance, professor James D. G. Dunn in his most recent monumental theological works on Jesus has acknowledged that the historical Jesus most probably didn't speak a word of what the Gospel of John portrays Jesus as having said.
Chris also has a five-part series on the discrepancy between the day of the week in which Jesus died according to the three Synoptic Gospels, compared with the day mentioned in the Gospel of John, titled, "The Date of Passover and the Pitfall of Inerrancy."
(Perhaps J. P. Holding and Dave Armstrong might consider reading Chris's pieces and offer to explain to the bright young lad why his questions, like Dr. Dunn's, aren't worth focusing any serious attention on.)
