1 Corinthians 1:23

but we preach Christ crucified, unto Jews. stumblingblock, and unto Gentiles foolishness;

'unto Jews. stumblingblock' -'To the Jews it was incredible that one who had ended life upon. cross could possibly be God's Chosen One. They pointed to their own law and the law unmistakably said, "He that is hanged is accursed of God." (Deuteronomy 21:23) To the Jew the fact of the crucifixion, so far from proving that Jesus was the Son of God, disproved it finally.' [Note:. Barclay pp. 19-20]

They never thought that Jesus might have been accursed of God, because He was dying for "our sins"! (Galatians 3:13; 1 Peter 2:24) They overlooked the clear passages that described the future Messiah, as. suffering servant. (Isaiah 2:1)

'unto Gentiles foolishness' -'To the Greek idea the first characteristic of God was..the total inability to feel. The Greeks argued that God cannot feel. If God can feel joy or sorrow or anger or grief it means that some man has for that moment moved and affected God. If that is so it means that for that moment that man has influenced God and is therefore greater than He is..A God who suffered was to the Greek. contradiction in terms.' (Barclay pp. 20-21)
