Historical background of the New Testament

Most scholars who study the historical Jesus and early Christianity believe that the canonical gospels and the life of Jesus must be viewed within their historical and cultural context, rather than purely in terms of Christian orthodoxy. They look at Second Temple Judaism, the tensions, trends, and changes in the region under the influence of Hellenism and the Roman occupation, and the Jewish factions of the time, seeing Jesus as a Jew in this environment; and the written New Testament as arising from a period of oral gospel traditions after his death.
