I suggest that all your quotes above prove that the bible was written by Rabis and not by god.
Your answer to the last quote is quite interesting. You seem to agree that all sin is equal. That actually is close to ancient hebrew thinking. The law for them was like a boundary. You could not cross the boundary, but you could get as close as possible without invoking what you call sin. In fact, all the action in commerce and law was close to the boundary. Still is today.
Jesus made a fundamental revision of this kind of thinking that you do not seem to recognize. He introduced that idea of perfection in that the closer you get to the center of purity, and the further you are from the boundary, the better person you are. One example of that is his statement that if you merely look at a woman with lust in your heart, you have committed adultery with her.
Now if all fundamentalists think as you do, and adhere to the old jewish way of thinking (Jews no longer think this way), then as Harvey points out in the above post, all you fundamentalists are guilty of ignoring the teaching of Christ.
BTW- the whole thing about Jesus being a sacrifice to remove our sin and abolish the old laws was a teaching of Paul/Saul, not Jesus. Jesus at the sermon on the mount said that you had to keep all the laws of moses in order to go to heaven. Perhaps that is why those quoted are so concerned with outdatted jewish law.
Again BTW- the reason jews find these laws to be outdatted is that there is no longer any unblemished red heffers, or a temple to sacrifice them in, or an unblemished Cohen to perform the ceremony.
Besides that moses gave the jews a means to modify existing laws and create new laws. That is what the Talmud is all about. If you want more current jewish law, just read the Talmud. It also is written by Rabis.
