Well burning a body to nothing in an inferno hides a body, and then of course crushing the bones to powder. So does submerging it bound in weights or placing it into a vat of lye or lime - all of which methods would have been available in Jesus’ time. History tells of many sects who proclaimed a founder’s miraculous resurrection - actually a common theme in the Mediterranean area at the time.
But what’s funny how we Catholics were always taught - overtly or covertly - to use only the Jews as the foil. And while Jews were the local power and culture from which Jesus arose, and certainly had a hand in his death, his story would fall on much more powerful ears - especially well after he died.
Lets think of a new paradigm - lets think of Jesus’ miraculous Resurrection as a message carried by and needed by the Roman Empire - especially 300 years after he died!
The Romans truly would be the ones who needed to preserve the Resurrection story, especially as they faced assaults from within and without. Constantine adopted Christianity (as many Emperors adopted all sorts of spiritual notions) and the story became entwined with what was left of the might, authority and power of the fading Roman Empire and would be reborn later in Constantinople and catapulted throughout all of Europe under the Holy Roman Empire - and the construct would be complete - God rules - Jesus came to Earth as the transfer from God to Man, and his vicar on earth, originally the Emperors, then the Pope and from the Pope to Holy Roman Kings, then Queens, all their Authority carried and supported through the Resurrection story
To me, if anyone had motive to hide Jesus’ body, it was not the post crucifixion apostles nor was it the Jews. It was Rome who needed a Resurrected Christ - and Rome had a long, long history of adopting religions over centuries and various Emperors creating religions to propel their power.
