Roman crucifixion was a killing method, not a punishment that
people recovered from. The Romans were professionals at
execution and had extensive experience with crucifixion. The
process was designed to be certain and public. Soldiers
confirmed death before a body was released. They were
experienced enough to know the difference between
unconsciousness and death.
In the case of Jesus, John records that a soldier pierced his
side with a spear and that blood and water came out. Medical
analysis of this detail suggests it is consistent with death
from crucifixion, where fluid accumulates around the heart
and lungs. John presents this as something personally
witnessed and emphasises that the witness is reliable. This
is not the kind of detail a fabricator includes.
Pilate confirmed the death before releasing the body to Joseph
of Arimathea, a prominent figure whose identity could be
checked. Tacitus, the Roman historian with no sympathy for
Christianity, records that Christ was executed under Pontius
Pilate. The death of Jesus is not disputed by serious
historians, including those who reject everything else the
New Testament claims.
The suggestion that Jesus merely fainted on the cross and
revived in the tomb requires believing that a man who had been
flogged, crucifixed, and pierced with a spear recovered in a
cold tomb, unwrapped himself from burial cloths, rolled a
large stone away from inside, overpowered Roman guards, and
then convinced his disciples that he had conquered death. That
sequence of events is far harder to accept than the
alternative.
