4: No early Church debate.
The early Church debated many fundamentals, even the nature of the Resurrection, but not the fact of the Resurrection. That was a given.
In John’s account, when Peter and he enter the empty tomb they “saw the burial cloths there, and the cloth that had covered his head, not with the burial cloths but rolled up in a separate place.” For John, the sight shows that Jesus wasn’t taken away, and that he didn’t rise like Lazaraus did. Something new had happened. Says the Gospel: “he saw and believed.”
