Jozrael, I am not a theologian by a long shot, but I believe that what you have described above is a comparison of the Old Testament text (which is essentually the Jewish Torah) to the New Testament (which is primarily the reported teachings of Jesus).
Granted, Jesus was a Jew and observed many of the important laws of the time. How he departed from the various Jewish sects is still being sorted out by the great theological minds of our time. It is clear to me that our understanding of the bible as laypersons, lacks any sort of historical grounding that would likely clarify the beliefs of the day.
You have presented interesting questions, and I hope you receive better answers than mine among the other tfp member.
Also, welcome.
