Deicide

Deicide is the killing (or the killer) of a god. The concept may be used for any act of killing a god, including a life-death-rebirth deity who is killed and then resurrected.
The term deicide was coined in the 17th century from medieval Latin *deicidium, from deus "god" and -cidium "cutting, killing."

According to the New Testament accounts, the Judean authorities in Jerusalem under Roman rule, the Pharisees, charged Jesus with blasphemy, a capital crime under biblical law, and sought his execution. According to John 18:31, the Judean authorities claimed to lack the authority to have Jesus put to death, though it is doubtful what legal basis such a claim would have had; the Jesus Seminar historicity project notes for John 18:31: "it's illegal for us: The accuracy of this claim is doubtful." in their Scholars Version. Additionally, John 7:53–8:11 records them asking Jesus about stoning the adulteress and Acts 6:12 records them ordering the stoning of Saint Stephen.
They brought Jesus to Pontius Pilate, the Roman Prefect of Judea, who was hesitant and let the people decide if Jesus were to be executed. According to the Bible, Pontius Pilate only ordered Jesus to be flogged. Washing his hands, Pilate said he would not take the blame for Jesus' death, to which the crowd replied, "His blood is upon us and our children."
Pilate is portrayed in the Gospel accounts as a reluctant accomplice to Jesus' death. Modern scholars say it is most likely that a Roman Governor such as Pilate would have no problem in executing any leader whose followers posed a potential threat to Roman rule. It has also been suggested that the Gospel accounts may have downplayed the role of the Romans in Jesus' death during a time when Christianity was struggling to gain acceptance in the Roman world.
The Catholic Church and other Christian denominations suggest that Jesus' death was necessary to take away the collective sin of the human race. The crucifixion is seen as an example of Christ's eternal love for mankind and as a self-sacrifice on the part of God for humanity.
The Gnostic Gospel of Judas contends that Jesus commanded Judas Iscariot to set in motion the chain of events that would lead to his death.
Against certain Christian movements, some of which rejected the use of Hebrew Scripture, Augustine countered that God had chosen the Jews as a special people, and he considered the scattering of Jewish people by the Roman Empire to be a fulfillment of prophecy. He rejected homicidal attitudes, quoting part of the same prophecy, namely "Slay them not, lest they should at last forget Thy law" (Psalm 59:11). Augustine, who believed Jewish people would be converted to Christianity at "the end of time", argued that God had allowed them to survive their dispersion as a warning to Christians; as such, he argued, they should be permitted to dwell in Christian lands. The sentiment sometimes attributed to Augustine that Christians should let the Jews "survive but not thrive" (it is repeated by author James Carroll in his book Constantine's Sword, for example) is apocryphal and is not found in any of his writings.
