What was so foolish about the cross?
“The Christian good news is all about God dying on a rubbish-heap at the wrong end of the Empire. It’s all about God babbling nonsense to a room full of philosophers. It’s all about the true God confronting the world of posturing, power and prestige, and overthrowing it in order to set up his own kingdom, a kingdom in which the weak and the foolish find themselves just as welcome as the strong and the wise, if not more so”.
N. T. Wright, Paul for Everyone: 1 Corinthians.
