18For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. 19For it is written“I will destroy the wisdom of the wise; the intelligence of the intelligent I will frustrate.”c

20Where is the wise person? Where is the teacher of the law? Where is the philosopher of this age? Has not God made foolish the wisdom of the world? 21For since in the wisdom of God the world through its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe. 22Jews demand signs and Greeks look for wisdom, 23but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles, 24but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God. 25For the foolishness of God is wiser than human wisdom, and the weakness of God is stronger than human strength.

26Brothers and sisters, think of what you were when you were called. Not many of you were wise by human standards; not many were influential; not many were of noble birth. 27But God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong. 28God chose the lowly things of this world and the despised things—and the things that are not—to nullify the things that are, 29so that no one may boast before him. 30It is because of him that you are in Christ Jesus, who has become for us wisdom from God—that is, our righteousness, holiness and redemption. 31Therefore, as it is written: “Let the one who boasts boast in the Lord.”

“What no eye has seen,

what no ear has heard,

and what no human mind has conceived”

Though, I am curious where I have said anything silly.

I was not tense, Roman. Its all good. I hope your silly pants are comfortable.

Wow. Max you need to loosen up. That was meant as a joke

Whatever you need to do.

Roman,
The Jews did not execute Jesus. Pilate did, for the crime of sedition. And since it was Pilate, it was Rome that did the killing. Rome was not a Jewish state, so Jewish custom was irrelevant. What happened to most criminals crucified by the Roman state at the time? They either fed carrion birds by hanging from the cross, picked apart until they fell apart, or were tossed in an unmarked graves and more carrion critters ate. Rome was under no obligation to follow any Jewish custom for a criminal condemned for sedition. It is unlikely that Pilate, not over-praised for his restraint and kindness by Josephus, would have made an exception in the case of an unremarkable peasant, with no influence. His own followers, also people of no social weight, had scattered. How likely is it that any jewish authorities were going to kick up a stir over the body of a person we are told they helped condemn? Not very likely at all. And even if they did, there is no reason to assume that Pilate would have acquiesced. Roman crime, Roman rules. I suspect that Jesus never came down from the cross, at least not for several days.

Highly unlikely that Jesus would not have been buried in a tomb or marked grave. Ancient Jewish Burial custom would never allow that - despite the claims of a lot of amateur scholars who are not adequately familiar with ancient Jewish culture. For proof of this, all you have to do is go through the Old Testament which is replete with example after example of Jews burying the wicked, executed criminals, those divinely judged for some crime, and even their enemies in battle. In the book of Tobit, (chapter's 1, 2, 4, 6 & 14) its made clear that his greatest virtue is his burying the dead including, including those executed by state authority.

I'm going to the mall today to get myself a pair of silly pants before we move on to the next topic

How exactly would people in antiquity "produce Jesus' body?"
Not many people would have known what Jesus looked like. Couple this with the fact that his body was likely not entombed anywhere, but that stayed on the cross at the worst, and was food for carrion birds, or, somewhat nicer, was pulled down after he died and tossed into a grave for condemned people. I strongly suspect that Jesus never came down from the cross.
