To make a huge show of His Resurrection and/or appear to Pilate and the Sanhedrin, etc would have been contrary to that and all he taught.
Resurrection wasn’t “hidden” it was certainly foretold....and God seldom acts according to how we would. more times than not you cannot see his hand work until after the fact.
Look at Jesus’s birth....everything about it was not even close to how we would see a Birth of a King.....nor of those invited to see the unfolding of this grand event.
Every eye will see Him when the time comes...you can with certainty know this!
