The Handbook / RES
The hinge of history.
A small set of facts is granted by nearly all historians who study the period, including skeptics: Jesus died by crucifixion; his disciples sincerely believed he appeared to them alive; the church persecutor Paul and the skeptic James were converted by what they believed were appearances; and the tomb was very likely found empty. Natural theories each explain one or two of these facts but fail on the rest. The resurrection explains all of them, and it is exactly what Jesus predicted.
Visions of the bereaved are real, but they don't fit the evidence. The appearances came to individuals and to groups, to friends and to enemies, at different times and places. They convinced a skeptic (James) and a persecutor (Paul) who were not grieving. And a vision does not empty a tomb. Most importantly, in Jewish thought, seeing a dead person would mean seeing a ghost or a spirit, not that he had been bodily raised. The disciples' claim was something hallucinations would not have produced.
Jesus was flogged, crucified and pierced by professional Roman executioners who confirmed his death, and both Roman and Jewish historians report that he was executed. Even if someone had survived such treatment, he would have been a broken, bleeding man needing months of care, not a victorious Lord who convinced his followers he had conquered death. That is why the swoon theory has been abandoned by almost all scholars, skeptical ones included.
The resurrection is not first found in the Gospels but in Paul's letters from the 50s AD, which quote a creed that most scholars date to within a few years of the crucifixion. That is far too early for legend to replace the core facts, especially while Peter, James and hundreds of other witnesses were alive. By ancient standards the Gospels themselves are also early: our main sources for Alexander the Great were written centuries after his death.
The Gospels differ in secondary details but agree on the core: Jesus was buried; on the first day of the week women, including Mary Magdalene, found the tomb empty; angelic messengers announced he had risen; and he then appeared to his disciples. Differences in peripheral details are what we expect from independent witnesses and from ancient biographers who selected and summarized. Historians do not reject an event because accounts of it vary in the details; identical accounts would suggest copying or collusion.
