The empty tomb narrative is the most conflicting story in all of Christian canon and apocrypha: How many women went—one, two, three, or at least five? Was the tomb open or closed when they arrived? Were there guards present? How many men or angels were inside or outside the tomb? Does Joshua appear and do they recognize him? Did the women tell the disciples? etc. To answer these questions, I'll defer to the Gospel of Mark, which is unanimously considered the earliest gospel and was copied by the authors of Matt and Luke (John may have known it as well) according to all modern scholars who have published on the Synoptic Problem. I'm not interested in debating this point, but if you have any peer review from the past 30 years to the contrary, please share it
To summarize the story in Mark ch. 15-16, Joshua is crucified at 9am on Friday and dies at 3pm. With evening approaching, Joseph of Arimathea, 'a prominent member of the council', asks Pilate for the body. This is required by Jewish law (Deut. 21:23) as Shabbot begins at sunset. Pilate is surprised that Josh is already dead—crucifixion is a slow death by suffocation and organ failure (often taking days)—and a centurion confirms that he is. Joe takes the body, wraps it in cloth, and brings it to a large, multi-chambered tomb. Mary of Magdala sees this, and on Sunday morning, she and two other women go to anoint the body. Upon arriving, they find the tomb open with a man inside who tells them:
[The End]“Do not be alarmed; you are looking for Yeshua of Nazareth, who was crucified. He has been raised; he is not here. Look, there is the place they laid him. But go, tell his disciples and Peter that he is going ahead of you to Galilee; there you will see him, just as he told you.” So they went out and fled from the tomb, for terror and astonishment had seized them, and they said nothing to anyone, because they were afraid.
Let's first discuss Joseph of Arimathea. The name implies he's from a small town and likely a relative newcomer to Jerusalem. Joe may have chosen to give Josh an honorable burial as he himself was from a rural area and more exposed and perhaps sympathetic to the apocalyptic ideas that Joshua of Nazareth preached. Sadducees, the minority sect who ran the temple, were the only significant group who didn't believe in resurrection—the Essenes and Pharisees (including Paul) practiced some form apocalypticism. Many of them, including Paul, Josh, and John the Dipper, believed that the end of the world was very near, in their lifetime (Mk. ch. 9 and 13)
Joseph may have been appeasing the crowd or perhaps took pity on Joshua, but it was almost certainly not meant to be a permanent resting place. Inside his family tomb was the decaying corpse of a crucified rebel, and Joe would surely feel pressure to move the body as soon as possible. This would've occurred on Saturday evening, or if he employed the help of non-Jews, any time on Saturday; or on Sunday before the women arrived. Joshua's closest followers had already left for Galilee. Wherever the body was moved, it would've been nearly unrecognizable within days if it were ever uncovered. While the guards in Matthew 28 are most likely not historical, it could represent a memory of centurions being present around the tomb
Next, the witnesses (or lack thereof). The women are the epitome of an unreliable narrator in Mark: they flee, frightened, and never tell anyone what they saw. This makes the accuracy of the retelling highly suspicious, and one can presume that when they were questioned by the disciples, their story of seeing a man who scared them wasn't believed, so a story was imagined, which changed over time from a man in Mark to the guards and angel in Matt, two angels in Luke, and Josh appearing to Mary but not being recognized in John. A single, unified story could not have created such discrepancies in the later narratives, and Paul's silence on the topic suggests that he was not aware of the story or didn't believe it was useful for spreading his gospel
Resurrection visions are beyond the scope of the hypothesis, but I'll note that it's very curious that in the earliest description of Joshua's appearance in Matt 28:16-17, not everyone believes: "Now the eleven disciples went to Galilee, to the mountain to which Yeshua had directed them. And when they saw him they worshiped him, but some doubted". In Luke 24:13-16, Josh appears to two disciples, but they don't recognize him, and Mary doesn't recognize Josh in John's tomb narrative. This suggests traditions that the disciples doubted their own visions of Joshua
