• on-biblical writings: The Jewish historian Flavius Josephus and the Roman historian Tacitus both mention Jesus in their works:
  • Josephus: In his 20-volume history of the Jewish people, Jewish Antiquities, Josephus mentions Jesus twice, including in the Testimonium Flavianum, which mentions Jesus’ brother James. Josephus also records that Jesus’ followers believed he was the Messiah. 
  • Tacitus: In his Annals, Tacitus mentions Jesus and connects him to his execution by Pontius Pilate. 
• Other non-biblical sources:
  • Pliny the Younger: In a letter to Emperor Trajan, Pliny wrote that early Christians would “sing hymns to Christ as to a god”. 
  • The Talmud: The Talmud mentions Jesus, including that he performed miraculous feats and was crucified on the eve of Passover. 
  • Lucian: Lucian mentions Jesus, including that he was regarded as wise and a powerful teacher. 
  • Justin Martyr, Ignacious of Antioch, and Clement of Rome: These contemporaries of the Apostles and their first followers wrote extensively about Jesus. 
• Thallus: Thallus believed that Jesus was a historical figure who was crucified. 

However, some say that the most detailed record of Jesus’ life and death comes from the New Testament, and that these writings are biased and should be evaluated critically.
