Although extra Biblical writing concerning the historical Jesus are simply redundant (since the Gospels and Acts are the earliest and most reliable sources of the life of Jesus of Nazareth) there are extra Biblical writings, enough to satisfy the most skeptical unbeliever.

Lawrence Mykytiuk is associate professor of library science and the history librarian at Purdue University. He holds a Ph.D. in Hebrew and Semitic Studies and is the author of the book Identifying Biblical Persons in Northwest Semitic Inscriptions of 1200–539 B.C.E. (Atlanta: Society of Biblical Literature, 2004).

Here are the major sections:

Works of Flavius Josephus
Works of Flavius Josephus

Roman historian Tacitus

Jewish historian Josephus

Greek satirist Lucian of Samosata

Platonist philosopher Celsus

Roman governor Pliny the Younger

Roman historian Suetonius

Roman prisoner Mara bar Serapion

And this useful excerpt captures the broad facts about Jesus that we get from just the first two sources:

We can learn quite a bit about Jesus from Tacitus and Josephus, two famous historians who were not Christian. Almost all the following statements about Jesus, which are asserted in the New Testament, are corroborated or confirmed by the relevant passages in Tacitus and Josephus. These independent historical sources—one a non-Christian Roman and the other Jewish—confirm what we are told in the Gospels:31

  1. He existed as a man. The historian Josephus grew up in a priestly family in first-century Palestine and wrote only decades after Jesus’ death. Jesus’ known associates, such as Jesus’ brother James, were his contemporaries. The historical and cultural context was second nature to Josephus. “If any Jewish writer were ever in a position to know about the non-existence of Jesus, it would have been Josephus. His implicit affirmation of the existence of Jesus has been, and still is, the most significant obstacle for those who argue that the extra-Biblical evidence is not probative on this point,” Robert Van Voorst observes.32 And Tacitus was careful enough not to report real executions of nonexistent people.
  1. His personal name was Jesus, as Josephus informs us.
  1. He was called Christos in Greek, which is a translation of the Hebrew word Messiah, both of which mean “anointed” or “(the) anointed one,” as Josephus states and Tacitus implies, unaware, by reporting, as Romans thought, that his name was Christus.
  1. He had a brother named James (Jacob), as Josephus reports.
  1. He won over both Jews and “Greeks” (i.e., Gentiles of Hellenistic culture), according to Josephus, although it is anachronistic to say that they were “many” at the end of his life. Large growthin the number of Jesus’ actual followers came only after his death.
  1. Jewish leaders of the day expressed unfavorable opinions about him, at least according to some versions of the Testimonium Flavianum.
  1. Pilate rendered the decision that he should be executed, as both Tacitus and Josephus state.
  1. His execution was specifically by crucifixion, according to Josephus.
  1. He was executed during Pontius Pilate’s governorship over Judea (26–36 C.E.), as Josephus implies and Tacitus states, adding that it was during Tiberius’s reign.

Some of Jesus’ followers did not abandon their personal loyalty to him even after his crucifixion but submitted to his teaching. They believed that Jesus later appeared to them alive in accordance with prophecies, most likely those found in the Hebrew Bible. A well-attested link between Jesus and Christians is that Christ, as a term used to identify Jesus, became the basis of the term used to identify his followers: Christians. The Christian movement began in Judea, according to Tacitus. Josephus observes that it continued during the first century. Tacitus deplores the fact that during the second century it had spread as far as Rome.
