Jews and other critics of Christianity in AD 30 Jerusalem never visually demonstrated that Jesus's body was still in its tomb.
• The belief that “he's alive” flourished in Jerusalem.
• They publicly granted that the body was gone.
• They weren't arguing “we showed the corpse.”
But so what? Couldn't it simply be that…
• …they didn't/wouldn't try to show it?”1
• …they couldn't locate Jesus's grave?”2
• …they couldn't prove the (decomposed) corpse was Jesus's?3
Mary visited Jesus's tomb and found that it was empty.
• The Apostles etc. said she did
• The Gospel of Mark's author said she did
• The originator of the “Mary saw it” report wasn't lying
In AD 30, the public stance of the Jerusalem Jews was that, “Yes, Jesus's body is gone from its tomb”, crying “theft!”.
• Matthew 28 says they did
• Those Jews were saying it in AD 70
But so what? Plausibly…
• …it was a lie, to counter claims that “Jesus's empty tomb proves He rose”?2
• …they erroneously believed Jesus's body was gone?3
Whoever started the claim that “Jesus's body is gone from it's tomb” was not telling a apologetics-motivated lie.
• …“missing body” evidence wasn't appealing
• …the lie was overtly falsifiable
• …clearly better lies were available
But so what? Perhaps it was Mary; she mistook an empty tomb for Jesus's?
Christians in AD 30 [were not saying that Jesus's body was gone from its tomb. [Full article.] This is relevant because Christians would have known if Jesus's tomb was empty, and they would have reported it.
After being crucified, Jesus's body was in fact not transferred to a tomb. [Full article.]
• …Jesus's corpse was left on the cross
