The question of the historicity of Jesus is part of the study of the historical Jesus as undertaken in the quest for the historical Jesus and the scholarly reconstructions of the life of Jesus. While the Christ myth theory proposes that Jesus never existed, nearly all historians reject the Christ myth theory and accept that a human Jesus existed, although few events mentioned in the gospels are universally accepted. Standard historical criteria have aided in evaluating the historicity of the gospel-narratives, and two events subject to "almost universal assent" are that Jesus was baptized by John the Baptist and was crucified by order of the Roman Prefect Pontius Pilate.
