Several non-biblical and extra-biblical documents from the 1st and early 2nd centuries mention Jesus or the early Christian movement. While almost no surviving documents were written during the active lifetime of Jesus by eyewitnesses who recorded him day-to-day (aside from early Christian letters like those of Paul starting in the late 40s/50s AD), numerous Roman, Jewish, and independent writings document his existence.

Jewish Historians and Texts

• Flavius Josephus (Antiquities of the Jews, c. 93–94 AD):
• Written by a Jewish historian under Roman patronage.
• The Testimonium Flavianum: A famous passage (Book 18) that describes Jesus as a wise man, a worker of extraordinary deeds, and a teacher who was crucified under Pontius Pilate and whose followers reported he rose again. Scholars generally agree the passage contains some later Christian additions/interpolations, but a core historical reference to Jesus is authentic.
• James Passage: In Book 20, Josephus mentions the execution of “James, the brother of Jesus, who was called the Christ,” which is widely considered authentic by historians.
• The Babylonian Talmud (Sanhedrin 43a, etc.):
• Rabbinic Jewish texts compiled over the first few centuries record traditions about Yeshu, noting that he practiced sorcery, enticed Israel to apostasy, and was hanged (crucified) on the eve of Passover.

Roman Historians and Officials

• Cornelius Tacitus (The Annals, c. 116 AD):
• A prominent Roman senator and historian.
• In Annals (15.44), while describing Emperor Nero’s persecution of Christians after the Great Fire of Rome, Tacitus writes that the name “Christian” comes from Christus, who was executed in Judea by the procurator Pontius Pilate during the reign of Tiberius. Tacitus was hostile to Christians, viewing them as a “mischievous superstition”.
• Pliny the Younger (Letters to Emperor Trajan, c. 112 AD):
• As the Roman governor of Bithynia-Pontus (modern Turkey), Pliny wrote to Emperor Trajan asking how to handle Christians. He noted that they gathered on a fixed day to sing hymns to “Christ as to a god” and live by strict ethical codes.
• Suetonius (The Lives of the Caesars, c. 121 AD):
• A Roman biographer and court official who wrote that Emperor Claudius expelled Jews from Rome because they were “making constant disturbances at the instigation of Chrestus” (a common Latin misspelling of Christus), reflecting early unrest in the Roman-Jewish community over Jesus.

Other Greco-Roman and Syrian Writers

Mara bar-Serapion (c. 73 AD or later):• An imprisoned Stoic philosopher from Syria who wrote a letter of comfort to his son. He compared the unjust deaths of three wise men—Socrates, Pythagoras, and the “wise king” of the Jews—noting that the Jews were justly punished by losing their kingdom shortly thereafter (alluding to the destruction of Jerusalem in 70 AD).
Lucian of Samosata (mid-2nd century AD):• A Greek satirist who mocked Christians, writing that they worshipped a “crucified sage” who introduced new laws and taught them they were all brothers.

Early Christian Documents Outside the New Testament

• The Didache (c. 50–70 AD):
• An early church manual (“The Teaching of the Twelve Apostles”) that outlines Christian ethics, baptismal practices, and prayers, preserving early oral traditions and sayings of Jesus.
• The Letters of Clement (1 Clement, c. 96 AD) and Ignatius of Antioch (c. 110 AD):
• Early pastoral letters written by church leaders who knew or succeeded the Apostles, documenting early Christian beliefs, the reality of Jesus’s crucifixion, and the structure of early communities.
