The resurrection and the best natural account compared
Research gradeTurns on background
The bodily resurrection explains the empty tomb and the appearances with a single cause. The best natural account needs a theft of the body within about a day and a half that, as Allison puts it, "must forever remain, in the nature of the case, hypothetical", followed by a series of experiences with "no close phenomenological parallel". Allison grants Christians, "with justice", that the natural account requires "an extraordinary confluence of remarkable circumstances". If God exists, and Jesus' life gave God reason to vindicate him (he claimed a messianic role, did deeds his contemporaries took as miracles, and was worshipped alongside God within about two decades of his death), the bodily resurrection is the better explanation. And if any supernatural element is accepted, the bodily form is the more economical one, because it also explains the tomb.
Turns on background. On the historical evidence alone the two explanations come out about even. For someone who rules out God, the natural account is best; on bare theism the comparison is even; on theism with a reason to expect God to vindicate Jesus, the bodily resurrection is the better explanation, modestly. In Allison's words, "The data constrain us by limiting possibilities, not by excluding all possibilities save one." The arguments for and against God, examined elsewhere in this research, leave theism a live, contested position, so the resurrection is a reasonable conclusion, though not a compelled one.

Every part of the natural account is an ordinary, documented kind of event: the theft of bodies, experiences of the dead after bereavement, visions spreading through a group, and the reinterpretation of a leader's death. Paul's own experience was visionary in form. Real but non-bodily appearances would fit the appearance evidence just as well. Even a background favourable to theism, Allison concludes, "does not demand the orthodox Christian verdict".
