As a follow-up to the points I was trying to make above in a fashion I am not happy with, I’'ll turn to Anglican scholar N.T. Wright who makes these cogent points:
Thus, Christianity was born into a world where one of its central tenets, resurrection, was universally recognized as false.
Except, of course, in Judaism. Resurrection was a late arrival on the scene in classic biblical writing, however. Much of the Hebrew Bible assumes that the dead are in Sheol, which sometimes looks uncomfortably like Hades: “The dead do not praise the Lord, nor do any that go down into silence” (Psalm 115:17). Clear statements of resurrection are extremely rare[2]. Daniel 12 is the most blatant, and remembered as such for centuries afterwards: “Many of those who sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt” (Daniel 12:2). Daniel is, however, the latest book of the Hebrew Bible.
In the postbiblical period, the Jewish group known as the Sadducees famously denied the future life altogether. The Sadducees, according to the first-century C.E. Jewish historian Josephus, held that “the soul perishes along with the body” (18.16). Other Jews spoke, platonically, of a disembodied immortality; according to the Jewish philosopher Philo of Alexandria, at death the philosopher’s soul would assume “a higher existence, immortal and uncreated.”[3] Still others appear to display some kind of resurrection belief, as in Josephus and the Wisdom of Solomon. “In the time of their visitation they will shine forth, and will run like sparks through the stubble. They will govern nations and rule over people, and the Lord will reign over them for ever” (Wisdom of Solomon 3:7-8)[4]. The clearest statements of resurrection after Daniel 12, however, are found in 2 Maccabees, the Mishnah and the later rabbinic writings. In 2 Maccabees, a martyr on the verge of death puts out his tongue, stretches out his arms and declares: “I got these from Heaven, and because of his Laws I disdain them, and from him I hope to get them back again” (2 Maccabees 7:11). According to Mishnah 10.1, “All Israelites have a share in the world to come; … and these are they that have no share in the world to come: he that says that there is no resurrection of the dead prescribed in the Law.”
Remember, resurrection does not mean being “raised to heaven” or “taken up in glory.” Neither Elijah nor Enoch had been resurrected in the sense that Daniel, 2 Maccabees and the rabbis meant it; nor, for that matter, had anyone else. Resurrection will happen only to people who are already dead. To speak of the destruction of the body and the continuing existence, however blessed, of something else (call it a “soul” for the sake of argument) is not to speak of resurrection, but simply of death itself. Resurrection” is not simply death from another viewpoint; it is the reversal of death, its cancellation, the destruction of its power. That is what pagans denied, and what Daniel, 2 Maccabees, the Pharisees and arguably most first-century C.E. Jews affirmed, justifying their belief by reference to the creator God and this God’s passion for eventual justice[5].
The doctrine remained, however, quite imprecise and unfocused. Josephus describes it, confusingly, in various incompatible ways. The rabbis discuss what, precisely, it will mean and how God will do it. Furthermore, the idea could be used metaphorically, particularly for the restoration of Israel after the Exile, as in Ezekiel 37, where the revived dry bones represent the House of Israel.
The early Christian hope for bodily resurrection is clearly Jewish in origin, there being no possible pagan antecedent. Here, however, there is no spectrum of opinion: Earliest Christianity simply believed in resurrection, that is, the overcoming of death by the justice bringing power of the creator God.

The good bishop puts it better than I did above.
