Acts 4:2

They were annoyed. While Jesus lived, the Pharisees were his worst enemies. But after his resurrection, the Sadducees became the stronger source of opposition to the messianic community, because they did not believe man survives death! "Christ on the cross" was offensive to the Jews and nonsense to the Gentiles (1 Corinthians 1:23). But first century preaching strongly emphasized the Risen Jesus and the resurrection of all the dead.
