Gospel of Peter >> provides more historical evidence that as time went by, early Christian writers tried to place more and more blame on the Jews.
The non-canonical Gospel of Peter, written sometime in the early 2nd century AD actually absolves Pontius Pilate and Roman soldiers of playing any role in the torture and crucifixion of Jesus – placing the blame for the murder and torture wholly on the Jews.
The Acts of Pilates, purportedly a letter written by Pontius Pilate himself, portrays Pilate as a convert to Christianity and entirely sympathetic to Jesus. Though the letter is an obvious forgery by an early Christian writer, it is another manifest attempt by early Christian writers to demonize Jews and make them entirely accountable for the death of Jesus.
You have no problem finding evidence that Christians blame Jews for killing Jesus, because the Jews killed Jesus (and for that they will burn in Hell, where the flames never cease). How about evidence that early Jews rejected culpability in killing Jesus?
