Not according to Paul himself, who claimed to have met the risen Jesus.
“But miracles don’t happen!” Diogenes says. If one starts off being 100% committed to the notion that God does not exist, or that he would never intervene in the world, then of course one will be led to that conclusion regardless of where the evidence points.
Note that I am not specifically arguing for the Resurrection at this point – or indeed, for any of the miracles of Jesus. As I said, that’s subject matter for another discussion, and we are dealing with the more modest issue of Christ’s existence. Rather, I’m pointing out the inaccuracy of claiming that the Bible contains no eyewitness testimony of anyone having met Jesus. Even if you adopt the most liberal views in existence with regard to New Testament authorship, one must still deal with Paul’s testimony. The only reason to reject his testimony right off the bat would be a prior commitment to the notion that Paul is wrong – that there is no God who intervenes in the world.
And of course, the whole notion of demanding eyewitness testimony for ancient historical events (or even more modern events) is woefully misguided anyway. For a discussion of philosophical principles for evaluating historical claims, check out Justifying Historical Descriptions by historian-philosopher C. Behan McCullagh. Suffice to say that it provides a much more thorough discussion that demonstrates the naivete of demanding eyewitness accounts.
