Designs.... were there not different views/sects in Judaism at the time of Christ? PSac has said before that a couple of friends of his - a Jewish scholar and a rabbi - say that there were different views on different matters. And if Judaism was going through (or even just had gone through) some sort of reform, doesn't different views stand to reason?
As for Paul - he was often an apostle to the gentiles, so the things he taught were new - to them.
As for Christ - the things he taught about the law might not have all been new - he UPHELD the law - but he taught and lived them without hypocrisy, and he brought that to the poor (ones who would be often overlooked) The new covenant was certainly new... and yes, even the NT makes it obvious that the jews believed in the resurrection, and why not? Its in the scriptures.
But what about the belief in a spiritual kingdom? What about the Son of God? What about those joined as brothers with Him, to rule/serve/minister with Him? What about sins being blotted out completely (no time-out for bad behavior) due to faith in Him, and/or His mercy?
Christ is the image of God. We see God, by seeing His Son. We know God, by knowing His Son. Not just because of what He taught, but because of how He lived and loved.
Even now, Designs, you must admit that Judaism has different sects and beliefs in matters such as the afterlife or the Messiah, over land and fighting, etc?
