Let us consider Method and the Resurrection appearances:
Historians try to establish what “probably” happened in the past. An historian would never claim a miracle “probably happened,” because a miracle is the “most improbable” thing that could happen, by definition. Only an apologist would fallaciously try to establish the historicity of a miracle, because sound historical reasoning rules out the “miraculous explanation” a priori.
Take this example: The pre Pauline Corinthian Creed claims something like the idea that the risen Jesus appeared to Cephas and the Twelve three days after Jesus died. This creed is very early and so the story may not be the result of legendary embellishment. So what happened? (a) Maybe the disciples were hallucinating out of grief. (b) Maybe Cephas and the twelve were inventing stories of the risen Jesus in hopes of lending divine clout to, and carrying on, Jesus’ ethical mandate of loving your neighbor and your enemy – an ethical cause they may have been willing to die for (like Socrates). Whatever the case, any reasonable secular explanation is historically preferable to a miraculous one.
In his debate with William Lane Craig, Bart Ehrman points out that even if we don’t accept a particular mundane explanation, it is still more probable than the miraculous explanation. In fact, in the case of an apparent miracle, even if we don’t know of any Aliens having cloaked ships and transporters that are doing “apparent” miracles on our planet (like in Star Trek: The Next Generation – Devil’s Due), this naturalistic explanation is still a more reasonable explanation than a secular historian claiming a miracle happened:
If anyone is interested, I explain this a little more fully in a blog post (along with the reader comments) here:
