EnoughisEnough:
I think you are on to something.
Look at history. The history of the Jewish people and their religion.
We are introduced to 2 religious groups in Israel in the New Testament - the Sadducees and the Pharisees. The Sadducees outnumbered the Pharisees and had more influence. Their role in society was to keep the Israelite religion free from outside influence and preserve the Mosiac Law as well as temple worship. The majority of Israelite history has the Israelites holding no belief in life after death. The New Testament shows that the Sadducees strongly held this belief.
The Pharisees on the other hand did were religious progressives. They believed that God was soon going to end all the wicked on the Earth, usher in this utopian kingdom on Earth, and raise all the righteous dead in new bodies. The Pharisees believed in resurrection.
There was a third set of beliefs by Jews - immortality. In Josephus' writings we are made aware of the Essenes who believed that a person consists of 2 parts - a body that disintegrates and an immortal soul that would enjoy a pleasant afterlife.
Keep in mind, most Israelites were neither Sadducees or Pharisees. There are no writings that reveal what the every day Israelite believed. What we do know is it comes down to one of three views -
- Annihilation (The oldest held belief)
- Immortality (Thanks to Greek influence)
- Resurrection
