Was Paul Crucified for you?

I'm reading this book "The Mark of Jesus" by Timothy George and John Woodbridge. Since my recent posts have been about 1 Corinthians, I thought posting this would be fitting, it's kind of what I've been trying to say, but seeing it said by someone else is always good, lol.

"Was Paul cruficied for you?" Here Paul reminds the Corinthian believers that their lives in Christ are inextricably bound up with what happened one Friday afternoon in Jerusalem outside the gates of the city when Jesus was impaled on a Roman cross. Why does he mention the cross at this point? Because the Cross is where all bragging stops. Behind all the side-choosing and sloganeering - "I am of Paul," "I am of Apollos," etc.-was the self-assertion and self-glorification of those who had an overweening confidence in their own virtues and abilities: the wise, the weighty, and well-born, as Paul refers to them in 1:26. The comman anthropological assumptions of Greek philosophy and Helenistic culture, not unlike those of the modern cult of self-esteem, greatly valued human assertiveness in any form as a badge of excellence, strength, and virtue. Indeed, the word 'virtue' comes from the Latin 'virtus,' meaning "manliness" or "worth." Physical prowess (cf. Augustine's recollection of how his pagan father Patricius used to take pride in showing off his well-formed adolescent son in the public baths), military feasts, oratorical abilities, intellectual acumen, political power, monetary success, social status - all of these were things to be proud of and to glory in.
But in contrast to all of this, Paul held up something utterly despicable, contemptible, and valueless by any worldly standard - the cross of Christ. For two thousand years the cross has been so variously and beautifully represented in Christian iconography and symbolism that it is almost impossible for us to appreciate the sense of horror and shock that must have greeted the apostolic proclamation of a crucified Redeemer. Actually, the Latin word 'crux' was regarded as an expression so crude that no polite Roman would utter it in public. In order to get around this difficulty, the romans devised a euphemistic circumlocution, "Hang him on the unlucky tree" (arbori infelici suspendito), an expression that comes from Cicero. But what the world regarded as too shameful to whisper in polite company, a detestable object used for the brutal execution of the dregs of society, Paul declared to be the proper basis for exaltation. In the cross, and the cross alone, Paul said, he would make his boast in life and death, for all time and eternity.
