Did the Father do it alone? Jesus Himself? The Holy Spirit? Was it teamwork? Is it a sin to care how it happened?
We know that after his resurrection Jesus could appear and disappear suddenly and go through closed doors. So, it is quite conceivable that He simply walked out of the tomb. Later, an angel came down and removed the rock at the door in order to make the resurrection known and to let the women in.
The pseudepigraphical Gospel of Peter is more detailed in its account of the events after the Crucifixion than any of the canonical gospels, it states:
"9. And in the night in which the Lord's day was drawing on, as the soldiers kept guard two by two in a watch, there was a great voice in the heaven; and they saw the heavens opened, and two men descend with a great light and approach the tomb. And the stone that was put at the door rolled of itself and made way in part; and the tomb was opened, and both the young men entered in. 10. When therefore those soldiers saw it, they awakened the centurion and the elders, for they too were close by keeping guard.
"And as they declared what things they had seen, again they saw three men come forth from the tomb, and two of them supporting one, and a cross following them. And the heads of the two reached to heaven, but the head of him who was led by them overpassed the heavens. And they heard a voice from the heavens, saying, You have preached to them that sleep. And a response was heard from the cross, Yes."
Of course, this is not to be believed. I quoted it for fun.
