Jesus Christ

 was the central figure of Christianity. According to the Roman Gemellus, he lived during the time of the Caesars Augustus and Tiberius in the regions of Judea and Syria. (PDA: Byzantium!)

Jack Harkness implicitly compared Jesus' conception to how a Nostrovite exobiologically implanted its eggs into Gwen Cooper. (TW: Something Borrowed)

Those who came to follow Jesus as a deity believed he was the messiah, "Christos" meaning "saviour" in Greek. Others thought of him as "a maverick rabbi", or a "false prophet".

Gemellus maintained that he was a carpenter's son, a child prodigy, and "extremely handsome, charismatic and persuasive". He was able to amass great audiences when he spoke, and his lectures often attacked Judaism as inadequate to inform the rigours of daily life.

Eventually, betrayed by Jewish religious leaders who had become jealous of his abilities, he was nailed to a stauros, or cross. In the 21st year of the reign of Tiberius Caesar, the Pharisees, leaders of the Jewish community, influenced the Roman procurator of the area, Pontius Pilate, to have Jesus executed for heresey.

Gemellus also knew of a story, of which he was no great believer, that Jesus' body, after death, had somehow vanished after its entombment. Christians, he said, believed that he had come back to life, resurrected by the Jewish God.

Christians from just after the time of Christ believed they were being systematically suppressed by the same combination of Jewish and Roman interests who had killed Jesus. The First Doctor once met a man named Daniel who insisted that the Jewish establishment in Jerusalem was conspiring to discredit Christianity. (PDA: Byzantium!)

Owen Harper compared himself to Jesus, as both came back from the dead. (TW: A Day in the Death)

The Tenth Doctor claimed to have been present at Christ's birth (DW: Voyage of the Damned) and to remember what really happened at his death. (DW: Planet of the Dead)
