Stephen is traditionally venerated as the protomartyr or first martyr of Christianity. According to the Acts of the Apostles, he was a deacon in the early church at Jerusalem who angered members of various synagogues by his teachings. Accused of blasphemy at his trial, he made a speech denouncing the Jewish authorities who were sitting in judgment on him and was then stoned to death. Saul of Tarsus, later known as Paul the Apostle, a Pharisee and Roman citizen who would later become an apostle, participated in Stephen's martyrdom.

The Acts of the Apostles is the fifth book of the New Testament; it tells of the founding of the Christian Church and the spread of its message to the Roman Empire.
