1 Corinthians 1:23

But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness (KJV)

Then: Paul keeps talking. He continues to explain the problems of the human mind in accepting the counterintuitive. Christ, the long-awaited Messiah, could not possibly have come as a normal everyday person who was put to death. The Messiah would be King over and above all others, not a servant subject to earthly laws. Neither could the Greeks comprehend any god choosing those without education, wealth, or status to bring a message of truth, let alone, The Truth.

Now: No matter the culture, Christ crucified is still a stumblingblock, still foolishness. People misunderstand until somehow, some way, epiphany comes into their lives.
