-We have no indication that writers in antiquity who opposed Christianity questioned the existence of Jesus
-There is no physical or archeological evidence for Jesus, and all the sources we have are documentary. The sources for the historical Jesus are mainly Christian writings, such as the gospels and the purported letters of the apostles. The authenticity and reliability of these sources has been questioned by many scholars, and few events mentioned in the gospels are universally accepted
-In conjunction with Biblical sources, three mentions of Jesus in non-Christian sources have been used in the historical analyses of the existence of Jesus. These are two passages in the writings of the Jewish historian Josephus, and one from the Roman historian Tacitus.
Virtually all modern scholars of antiquity agree that Jesus existed, and most biblical scholars and classical historians see the theories of his non-existence as effectively refuted. In antiquity, the existence of Jesus was never denied by those who opposed Christianity. Christopher Tuckett states that the existence of Jesus and his crucifixion by Pontius Pilate seem to be part of the bedrock of historical tradition, based on the availability of non-Christian evidence.
