Also, would you mind telling us where the tzitz eliezer and rav yaakov emden say such things?
Rabbi Dovid tzvi hoffman would not be surprising, as i mentioned sbove, yekkishe rabonim started going with this shita around the time of rav hirsh.
Rabbi kook’s use of it is no more convincing to me than his assessment of the nevala-painting Rembrandt as a “tzadik” because of his painting of the tosfos yom tov.
The term “gadol hador”…there were no zionist rabbis who were acknowledged by the entire torah world as being its leader. Whereas the converse is true – dati leumi people accepted the chazon ish, rav Moshe feinstein wnd rav elyashiv despite not being at all from their camp. The yeshiva and chassidish world did not accept rabbi yoshe ber soloveitchik as a leader of the generation, nor did they accept rabbi kook after the gedolim vegan distancing themselves from him.
There’s a reason why in no mainstream yeshiva will.you find the books of rabbi kook or rabbi yoshe ber soloveitchik, though the latter you will sometimes come across.
every dati leumi yeshiva has an igros moshe.
