The Stoning of Stephen.
Wasn’t capital punishment prohibited when the Jewish leaders stoned Stephen at the time of Messiah.
Dr. Fruchrenbaum’s answer:
The stoning of Stephen took place at an “opportune” time, when a Roman procurator had passed away, and the new procurator had not yet arrived on the scene. With no procurator to control matters, the Sanhedrin — through a mob scene — were able to carry out Stephen’s execution, though it was quite illegal.
