A few issues regarding the New Testament.

It seems to me worthwhile to mention something I find odd in the New Testament. It is not just that Jesus says to keep the entire Torah including the Oral Law. ["The Pharisees sit on the seat of Moses, and therefore all that they say to do that you must do..."] The thing I find curious is that wherever you look, Jesus is always depending on the authority of the Law of Moses, ---not just once or twice. I mean to say Christians may quibble about what it means when he says that the Law is eternal and will never be nullified. But how can you quibble with the fact that he considers the Law to be obligatory on himself and all others.?? See for example: the golden rule. The golden rule is the law and the prophets. So if the law was nilified, how would that make sense? So how can you argue with that? True that Paul does say that gentiles do not have to keep the Law. However that is understood anyway since the most commandments were addressed to Israel. [Later it does look like Paul wavers on this point. But that does not seem relevant to the basic issue about what Jesus held. Paul was addressing gentiles and so the issue just does not come up at all.] A few more comments about this might be in order. One is the Sabbath day of rest. Ears of wheat that are not in need of the ground one can pick on Shabat. That is to say if they are totally ripe. So what the disciples of Jesus were doing on Shabat was totally permitted. While it is true that picking unripe wheat is one of the 39 kinds of forbidden work, still picking ripe wheat is not. And unless there is a specific degree from the sages not to pick even ripe fruit or wheat we do not make up our own decrees. [I mean to say that while there are plenty of decrees from the sages but after the time of the sages of the Mishna we can no longer make up our own decrees. This authority lasted only up until the end of the Mishna period. Even amoraim could no longer make decrees.]

To address another problem in the New Testament: The Oral Law. On one hand in Mathew 23 does say to listen to the Oral Law. "The scribes and Prushim [Pharisees] sit on Moses's seat and therefore all that they command you to obey that you must obey."
The Prushim a group that was fanatically religious and not the ancestors of the sages of the Mishna. However the Prushim did accept the Oral Law, but added tons of their own restrictions. [They were not the teachers]] They are well known all throughout the Gemara. For example they ate "חולין על טהרת הקודש" regular food as if it was the remainder of sacrifices. [note 1]That is it can not come into contact with anything "Tamee" unclean.
  Obviously this is not a restriction of the sages of the Mishna and certainly nothing that the sages of the Mishna did or taught as being desirable in any shape or form. So clearly the Prushim are not in any way related to the actual sages.


[note 1]
[I mean to say that there are different degree of "Tuma", an Av (a principle), a 2nd, 3rd or even a forth degree.  Food can be eaten no matter how unclean "tame" it is. even if it has been touched by a dead lizard. Only the food of sacrifices or truma has to be clean. That is let's say you have decided to thank God for some deliverance. So you bring a thanksgiving offering to the Temple. The priests then sacrifice the animal and you get part of the meat. That meat must be kept clean. In fact eating it in a state of tuma is Karet. But eating it when it is tame is not karet but still a prohibition from the Torah.

And since it is derived from a sacrifice it can become tame even to the forth degree. That is a dead lizard touches food. That food is allowed to be eaten--but it is a Rishon. [First degree of Tuma]. Then that food touches other food. That other food becomes a Sheni [2nd degree]. Then that other food touches more food. If that last one is truma then it becomes a 3rd degree. If that truma then touches the leftovers from the thanksgiving offering then those leftovers become a forth degree and can not be eaten. But none of this applies unless one has in fact brought a sacrifice.

There are many more issues. One is "sonship". A soul of Atzilut has the category of son. Souls from the next lower world "creation" do not have that level but rather are called servants. Most people have souls from the lower worlds. Only souls from Emanation are called "son".This is all very well explained in the Ari-Rav Isaac Luria.
