The Handbook / JES
Who was he, and who did he claim to be?
Almost every historian of the ancient world, Christian or not, agrees that Jesus of Nazareth existed and was crucified under Pontius Pilate. He is mentioned by Roman and Jewish writers within about a century of his death, and Paul's letters, written within twenty to thirty years, name people who knew Jesus personally, including his brother James. By ancient standards, that is excellent evidence. The real debate is not whether Jesus lived, but who he was.
Jesus rarely used the bare words 'I am God', because in a Jewish setting that would have been confusing. Instead he did and said things that only God could rightly do: he forgave sins against others, claimed authority over the Sabbath and the Law, accepted worship, and told the high priest he would sit at God's right hand and come on the clouds. His hearers understood him, and both times they tried to stone or condemn him for blasphemy. These claims appear in the earliest Gospel, not just in John.
When you check the ancient sources themselves, most of the claimed parallels disappear. Horus was not born of a virgin on December 25 and had no twelve disciples; Mithras was born from a rock and is never said to die or rise; Dionysus' stories are about a god, not a recent man executed under a Roman governor. Specialists in ancient religion have largely abandoned the idea of a common 'dying and rising god' pattern. The Gospels describe a Jewish man in datable history, and their roots are in the Hebrew Scriptures, not pagan myth.
Jesus' teaching cannot be separated from his claims about himself. He forgave sins, said people's eternal destiny depends on their response to him, and claimed to share God's authority. A merely human teacher who said such things would not be good; he would be either badly deluded or deliberately deceptive. That leaves an uncomfortable choice. 'Good teacher only' is the one option Jesus did not leave open.
Some fulfillments in the Gospels are direct predictions; others are patterns, where Israel's history foreshadows the Messiah. Recognizing this answers many objections. And the central fulfillments could not easily be staged or invented: a Messiah from David's line who would suffer, be pierced and die for others' sins, and then be vindicated. A crucified Messiah was a scandal, not something anyone would invent to fit expectations. Jesus himself taught that the whole of Scripture points to him.
