1. You will first have to learn Hebrew then the Talmud to understand anything that’s going on between the Pharisees and Jesus.
2. Pharisees includes both righteous G-d fearing Jews and also corrupt Jews. But because they were leaders and some were heretical Jesus had rebuked them. For we know many Pharisees that also believed in Jesus.
3. Just so you know I’m not crazy and the NT is a jewish text, Jesus brings down that “circumcision” is permitted on Shabbat (I.e. cutting foreskin or bleeding are 2 of 39 Biblical Forms of “melacha” - creative work). Hebrew is very rich and there are various types of work. Proof that all Jews and Jesus agree to this law that Shabbat can be broken for we are also commanded on the 8th day to circumcise a boy. So which law is heavier? That’s great explained in the Talmud as well as Jesus brings it down
4. Saving a life mean and you break all Shabbat laws if needed because life isn’t much greater. HOWEVER some Pharisees who were “legalistic” like “SOME CHAREDI’s” in the Orthodox world, wouldn’t even break Shabbat to save a life. Jesus would rebuke these same type of Jews today but most Jews know to break Shabbat for a life.
5. Therefore it is a given that if physical life can be saved then a spiritual life can be saved since that’s all the more greater! And Shabbat is a very spiritual day too, this Jesus did NOT break Shabbat according to the Torah but SOME (NOT ALL) Pharisees did not like this because they were “overly religious” and looked passed the meaning or “purpose” of G-d’s PERFECT (NOT OLD) Torah.
I hope that makes sense
You don’t learn this in Sunday school sadly and because they don’t know and just ignore the fact that there is so much to know from the Torah before understanding this occurrence
