DH,
Its how I’ve been taught. It may be hard for me to be explicit on YWN about it, but basically, I don’t believe in the infallibility of chazal. I don’t believe that they never made any mistakes.
For example, I don’t believe the sun goes “behind” the rakiah at night. But that’s irrelevant to following halacha.
Not that it changes halacha. I also believe in the halachic process – I think you need a living process in order to make a viable way to follow Torah Judaism. Contemporary rabbonim pasken based on historical context and extrapolate to the contempary needs of the people. There is a reason Torah lo bashamayim he is so important.
I have never been taught that everything chazal and the great leaders of the past said is 100% true. Even in my RW elementary school.
