Tacitus reports that Christus was executed under Pontius Pilate during Tiberius’s reign and that the movement spread from Judea to Rome (Annals 15.44). Josephus’s Antiquities 20 refers to James as ‘the brother of Jesus, who was called Christ’; this shorter reference is accepted as authentic by the large majority of scholars. Pliny documents Christians worshipping Christ and refusing to curse him around A.D. 112.
Precision matters. Suetonius’s ‘Chrestus’ may reflect disputes about Christ, but it is not certain. Mara bar Serapion’s ‘wise king’ is suggestive rather than explicit. Celsus and Lucian show hostile critics treating Jesus and his followers as historical, but they write later. None of this proves the resurrection by itself. It does make the claim that Jesus was simply invented as a nonexistent person a poor fit for the ancient evidence.
