Pesak
Question
The Torah says that if you have a question you are to go to the rabbis of your time. But if a pesak was given by a rav of a previous generation, it doesn't become void just because he passed away, yet you imply that it does when you say that R. Moshe's pesak re. gelatin is no longer binding (I am not referring here to the claim that today hewould rule that it's mutar). Similarly, R. Zvi Pesah Frank's permission to eat gelatin does not lose its authority when he passed away. A talmid of either of these gedolm is supposed to follow their rebbe's shitah, even if he is no longer alive.
Answer
Answered by Aaron Abadiyou say, "is supposed to follow their rebbe's shitah." If that's the case, how come all the years students differed from their teachers. Rabah says one thing & Abaya argues, even though Rabah was his teacher. And this exists throughout history. Maybe you need to take a better look at how it works before presenting your opinion. AA
