o Read Acts 4:1-12. 4:2: "they preached in Jesus the resurrection of the dead."

You have to hand it to the priests, and especially the Sadducees (who did not believe in the resurrection at all).  At least they could recognize the most critical truth to confront.  It is not the message of the cross by itself.  Many men died on  crosses in Roman times, thousands.  And some of them claimed to be "the Christ", the One to be anointed King (Acts 5:36-37).  But only One ever, ever was resurrected.  Only One!  It was Jesus!!  This message had to be stopped because anyone who believed Jesus was raised from the dead must bow before Him as Lord.  There can be salvation in no One else (v12).
