Steve Hays recently pointed me to a post by Michael Bird regarding the authorship of the fourth gospel. In that post, Bird refers to a White Horse Inn radio program that features interviews with several scholars commenting on the gospel's authorship (Craig Blomberg, G.K. Beale, Justin Holcomb, Richard Bauckham, D.A. Carson, Andreas Kostenberger, and Lydia McGrew). The page Bird links doesn't seem to contain the relevant audio, but Patrick Chan found it here. I looked for the program through the White Horse Inn search engine, and it appears that the program originally aired in December of 2019. Apparently, you can't listen to the program at the White Horse Inn site, but you can listen at the site Patrick found. Contrary to what Bird reported, the host who favored something like Richard Bauckham's view of the gospel's authorship was Shane Rosenthal, not Michael Horton.
Some good points are made during the program, but some of the best arguments for authorship by the son of Zebedee aren't mentioned. Here's an article I wrote in 2017 in response to the second edition of Bauckham's book, Jesus And The Eyewitnesses (Grand Rapids, Michigan: Eerdmans, 2017). In that article, I discuss a lot of New Testament and patristic evidence not addressed by the White Horse Inn program.
I should add that Dean Furlong recently published a book that's relevant, based on his doctoral thesis, The Identity Of John The Evangelist (Lanham, Maryland: Lexington Books/Fortress Academic, 2020). His book doesn't say much about the New Testament, but is instead focused on the extrabiblical evidence. He argues that the John of Papias and other early sources was somebody other than the son of Zebedee. I disagree with him, for reasons like the ones referred to in my response to Bauckham linked above. But he makes a better case than Bauckham does, and I agree with some of the other points Furlong makes (the strength of the evidence for the martyrdom of John the son of Zebedee, the fact that Papias attributed the fourth gospel's authorship to his John the Elder, etc.). He provides a large amount of information on Johannine issues, and you don't have to agree with him about everything to find his book useful in a lot of contexts. It's a good resource to have, no matter what position you take on the identity of the author of the fourth gospel, who Papias' elder was, when Revelation was written, and the other issues involved.
