  1. 515 BC – AD 70

    Second Temple Judaism

    Location
    Judea and the Jewish diaspora
    People involved
    Priests, scribes, Pharisees, Sadducees, Essenes
    What happened
    After the return from Babylon the Temple was rebuilt and Jewish life was shaped by synagogue worship, scriptural study and messianic expectation. The Greek translation of the Hebrew Scriptures, the Septuagint, spread through the diaspora from the third century BC.
    Why it matters
    Christianity emerged inside this world; its Scriptures, vocabulary and worship patterns are unintelligible apart from it, and the Septuagint shaped which books early Christians read as Scripture.

    Academic historians

    The crucifixion under Pilate and the existence of Jesus are attested outside the New Testament by Tacitus (Annals 15.44) and Josephus, and are accepted by the overwhelming majority of historians. The resurrection itself is a claim of faith that historical method cannot verify or refute.
