“The whole strength of our faith is in mesorah, the faithful transmission of the Torah from Rebbi to talmid.”
Read “Rupture and Reconstruction” by Prof. Chaim Soloveitchik (The Rav’s son) regarding how that has changed today.
“both Rav Kook and Rav JB Soloveichik regarding their inventions of their respective new ideas”
The charedi world is full of “new ideas”:
Rejection of secular education and even (in the case of the Old Yishuv) knowledge of languages. To be on the Sanhedrin you had to know 70 languages.
Kollel for the masses. No precedent ever for that.
Women being responsible for the economic wellbeing of their families, in direct violation of the language of every Ashkenazic ketubah written since the time of the Rishonim.
Halachic decisions being promulgated with no analysis of sources but only with appeals to authority. No precedent for that, either.
