Your post is a tightly packed mass of unsubstantiated allegations. Offer proof for each of these, and then we’ll talk.
The proof begins with the sure knowledge that Yeshua could *not* change a single thing in the Torah, OR, He is a false prophet. *nothing* added, and *nothing* taken away.
Secondly, in order to take on the sin of the world, he had to be innocent of *every* sin. In order for another to pay the debt, he must be free of the sin of the debt. Sin, by definition, is breaking the Torah. So again, there cannot have been any break with the Torah.
Lastly, as the Great Teacher, Yeshua's disciples follow His example - Any who would change what He said and lived by necessarily are not His disciples, as the purpose of a disciple is to preserve the teaching of the Rabbi. Saul broke the tradition of Gamliel to follow Yeshua as His disciple (cannot serve two masters [read: two rabbis])
Now compare. You will know them by their fruits.
Unless you can prove an authority to change what YHWH says is unchanging, there is no other proof necessary.
And speaking of 'a tightly packed mass of unsubstantiated allegations', what better to call a tradition that is proven upon the authority of the very organization that claims the tradition AS it's authority. One must wholly break with logic to accept such a premise.
