Many of the enumerated mitzvot concern ritual and ceremony that can only be obeyed within the establishment of the Aaronic priesthood and the ancient Temple functions. That is, ever since the Diaspara of the Jewish people, it has been literally impossible to fulfill all of the Torah’s righteous demands....
Jesus the Messiah kept all of the taryag mitzvot, and He is the only One who ever did. Therefore, being sinless, He became the only true Mediator between God and Man. As a result, Jesus became the only High Priest who could offer Himself up as the true kapparah (Sin-Bearer) of the world.
“Therefore God has also highly exalted him, and given him a name that is above every name: That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; and that every tongue should confess that Jesus Christ is Lord (Adonai), to the glory of God the Father” (Phil. 2:6-11).
