No one can assign collective guilt for the death of Jesus to the Jews. Instead, the Church professes with certainty that all sinners share in the guilt for Jesus’ death. [597-598]
The aged prophet Simeon foresaw that Jesus would become ” a sign that is spoken against” (Lk 2:34b).
And in fact Jesus was resolutely rejected by the Jewish authorities, but among the Pharisees, for example, there were also secret followers fo Jesus, like Nicodemus and Joseph of Arimathea. Various Roman and Jewish persons and institutions (Caiaphas, Judas, the Sanhedrin, Herod, Pontius Pilate) took part in Jesus’ trial, and only God knows their guilt as individuals. The idea that all Jews of that time or living today are guilty of Jesus’ death is irrational and biblically untenable.
