“Not after Him — just until Him!”

I’m sorry but I don’t understand the response. Jesus was under authority here as were the disciples. He came to fulfill all of the law and yet He worked on the Sabbath, He touched the lepers, He touched the dead, He did not wash before meals and He consorted with sinners, Gentiles and the ritually impure; all contrary to the teaching of the scribes and Pharisees.

[Philo-Junius]

“He came to fulfill all of the law and yet He worked on the Sabbath...”

Better to say “He did things on the Sabbath which some Pharisees considered work.” The proscription against healing on the Sabbath was never universal because many, if not most, rabbis understood that a treatable illness on Saturday might be terminal on Sunday, and everyone agreed that the Law allowed what would otherwise be “work” in order to save life.

Yet here He tells the people to do what the scribes and Pharisees say. At other times, he "breaks" the laws, which He has the authority to do only because He is God, Who made the Law in the first place. The momentous difference is that now the new Torah is to be spread to all the nations. You might read the section on this (including the discussion of Rabbi Neusner's book) in the Pope's Jesus of Nazareth.
