This question got me to looking for Non-Biblical documentation/accounts for Christ. Doing so I ran across this article:
Is There Any Evidence for Jesus Outside the Bible? (link)
citing some very ancient documents that seem to support the Gospel accounts of the events surrounding Christ:
The first account cited in this article comes from the secular scholar Thallus (52AD) as quoted by Julius Africanus, attempting to explain the darkness and earthquakes occurring during Christ’s crucifixion.
However, the following section in particular has a convincing support for me in that people do not typically hold on to a myth when tortured and threatened with death (the following also taken from the above link):
Cornelius Tacitus was known for his analysis and examination of historical documents and is among the most trusted of ancient historians. He was a senator under Emperor Vespasian and was also proconsul of Asia. In his “Annals’ of 116AD, he describes Emperor Nero’s response to the great fire in Rome and Nero’s claim that the Christians were to blame:
“Consequently, to get rid of the report, Nero fastened the guilt and inflicted the most exquisite tortures on a class hated for their abominations, called Christians by the populace. Christus, from whom the name had its origin, suffered the extreme penalty during the reign of Tiberius at the hands of one of our procurators, Pontius Pilatus, and a most mischievous superstition, thus checked for the moment, again broke out not only in Judea, the first source of the evil, but even in Rome, where all things hideous and shameful from every part of the world find their centre and become popular.”
In this account, Tacitus confirms several historical elements of the Biblical narrative: Jesus lived in Judea, was crucified under Pontius Pilate, and had followers who were persecuted for their faith in Christ.
There are quite a number of other secular/non-Christian documents cited in this acticle that I will let you, the reader, link to: Is There Any Evidence for Jesus Outside the Bible? (link)
With these accounts then it only make sense that the Leaders of the Sanhedrin or the Roman empire would have produced the Body of Christ as soon as the resurrection “myth” started, they would have placed guards at the Tomb, and given the secular documents, I have no doubt that the description in Matthew 27:62-66 where Pilate ordered the Tomb to be secured occurred. Thus, the body of Christ was observed by Roman solders being placed in the Tomb and that Tomb sealed.; thus, most probably preventing the easy theft of Christ’s Body either before or after the burial - these guards would have valued their lives, to fail a task given by the Prefect would have meant scourging if not death for these guards!
Both the leaders of the Sanhedrin and Pilate had much to gain politically by disproving the resurrection of Christ, much more so,. than by allowing the “myth” to continue and would have produced the Body of Christ if they could have done so… and I suspect that they turned the place upside down looking for Christ’s Body! Pilate may not have been a Nobel Piece Prize winner, but he wasn’t stupid, nor were the leaders of the Sanhedrin - they would have known very well that the resurrection of Christ had to be debunked as soon as possible to regain control of Christ’s followers and to quell unrest. Yet we do not see this happening, no indeed, instead we see decades later Nero still dealing with the Christians which doesn’t make any sense of the events if the Crucifixion and Resurrection didn’t occur as related in the Gospels and could have been discredited at the time of the Resurrection.
