Nowhere in the Bible or in old Jewish or Christian literature does the language of resurrection refer to a materially new body, physically unconnected to the old. A resurrected body is always the old body or a piece of it come back to life and/or transformed. . . . Resurrection meant bodies in the ground coming back to life. To rise from the dead was to rise from one’s tomb. Dale C. Allison, Jr., “The Resurrection of Jesus and Rational Apologetics,” Philosophia Christi 10 (2008): 315-338.
Surely that's overstated:
i) In reference to the Resurrection of Christ, I agree. That's because there was an extant corpse to resurrect. Indeed, his body had only been on ice for about 48 hours.
ii) But surely Christians and Jews were aware of the fact that sometimes there were no mortal remains (cf. 2 Kgs 23:15-16; Amos 2:1; Rev 20:13). In that case, there is no body in the ground to return to life.
In that event, resurrection requires a materially new body. In that regard, it's physically unconnected to the old. However, although it's numerically distinct, it can be a duplicate body. Discontinuous in one respect, but structurally indistinguishable.
