But we preach Christ crucified - A stumbling block to Jews and foolishness to Gentiles.
But to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.

Jews demand signs and Greeks search for wisdom - but we preach [the words of] Christ crucified !
A stumbling block to Jews and foolishness to Gentiles.
But to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.
