The Minimal Facts are:
- Jesus died by crucifixion
- Jesus’ disciples believed that He rose and appeared to them
- Saul, the persecutor of the Church, was suddenly changed
- James, the skeptical brother of Jesus, was suddenly changed
- Jesus tomb was found to be empty
Any attempt to explain the transformation of the apostles and the growth of the early Church must account for all five of these facts adequately. IMO, the resurrection has explanatory depth and scope that is missing from other explanations.
your scavenger theory accounts for only two of the five facts: the crucifixion and the empty tomb.
The resurrection theory, however, accounts for all five.
IOW, the resurrection theory has more explanatory depth and scope in terms of the five facts than the scavenger animals theory.
As you know, a situation is sometimes explained by more than one event. To be clear, the Resurrection does not explain all five facts, either, but rather only the empty tomb. Facts 2-4 are explained by other events, namely, Jesus’ post-mortem appearances.
As an aside, it’s not clear to me what you mean by “scope” as a criterion for preferring an explanation if not explanatory depth: The ability for a theory to be applied to more things does not make it any more likely to be true.
But we must first take a step back and ask how we know those are all facts. For example, why should we believe the Bible’s testimony that James was initially skeptical of Jesus? James even could have been a type of L Ron Hubbard, looking to build up a family member for profit of some sort, we have such little historical record of him if the Bible isn’t trusted. Saul suffering a bad mental event (e.g. stroke) could explain his temporary blindness and change of behavior, with the others either hearing a voice or seeing a light based on his own unreliable testimony rather than theirs.
Then the final fact to be explained is how Jesus’ disciples came to believe that He rose and appeared to them. It seems this fact is speculation if not assumption: If we don’t assume the Bible is reliable, then we don’t know how many of the Disciples actually came to believe; we don’t know how many of them were martyred for the faith; I don’t know that what I’ve been told from Catholic Answers is true, that disciples of a failed messiah simply gave up and looked for another one: Perhaps what skeptics have said is probable, that, being impressed with Jesus’ wondrous healing and inspirational teaching, they searched the Scriptures and found an explanation, with accounts of Jesus eating fish on the shore, miracles and mass conversions in Acts being propaganda.
My point isn’t that these natural explanations are to be preferred to assuming the Bible is true and assuming the Church’s tradition is true. My point is that it’s not clear from this point in time which set of explanations is actually true. Modern miracles don’t help me because they’re always remote and unverifiable. For example, recently in my Facebook newsfeed was a report of a 2013 Eucharistic miracle confirmed by the Church in Poland. It’s in Poland, not in my city; the investigation is not published for me to review like other scientific articles are; even if the study is done well, there’s no way to verify the Host was submitted for analysis rather than heart tissue from a cadaver. Fraud does occur, and people do atrocious things. So it seems that every miracle cited as evidence of the Church’s truthfulness and authority must likewise be believed on faith, which results from circular reasoning: One chooses to believe the Church, and then one chooses to believe the miracle because one has chosen to believe the Church.
I don’t understand why God values choosing to believe without reason or evidence – and please don’t miss my point: At a certain step in
every argument leading to God that I have seen, there is at least one step that must be blindly assumed, even if there is evidence before or after that point. (For example, archeological evidence corroborating the Bible’s claims about places existing and people living there does not demonstrate that the events occurred there as described.)
Why does God create us so finite, give us reason, insist that we rely on it for survival, and then take pleasure in our rejecting it to believe claims about Himself? Finally, my problem is that my suffering tips the balance against Christianity: On one end of the scale is a set of assumptions (in this case, that the Bible reliably presents history), and on the other end is the question of why my Heavenly Father is silently letting me suffer and not directly communicating with me (together with all the other problems in the world). The suffering makes the assumptions on which my faith is based look like wishful thinking.
