Crucifixion

The crucifixion is highlighted as the specific mechanism that exposes human wisdom's limits — God choosing Rome's most shameful execution method as the means of cosmic rescue is precisely what no human strategist would have designed.

The Crucifixion is referenced here as a chronological anchor — Paul notes most of the five hundred witnesses are still alive roughly twenty years after the event, making their testimony recent and checkable, not legendary.

The Crucifixion is named bluntly here as something the crowd participated in — Peter does not soften his indictment but uses it as the setup for the even more decisive act of God raising Jesus.
