Reply To: Question of an ignorant, closed-minded Lubavitcher

The question of perfection is a very broad question that is not specifically about Moshiach or the Rebbe, rather deep sugya in hashkofa which I didn’t have the patience or interest to share my thoughts on.

However, since people keep asking, I’ll share some general points for thought.

There is definitely some idea of perfection in true tzaddikim, specially as the Alter Rebbe defines a tzadik in Tanya (as mentioned by Sechel) that he is someone who has succeeded in completely eradicating evil impulses from his heart, thus blocking the possibility of sin.

We see similarly in Gemara Chulin 7a where the Gemara first assumes that R’ Meir accidentally ate a leaf without taking teruma, but then refutes this since its impossible that Hashem would allow a tzaddik to fall in sin.
This implies a certain degree of perfection.

On the other hand, the very idea that tzaddikim are human comes with an intrinsic degree of imperfection. This can be manifest in very minute yeridos which would even be praiseworthy for a simple Yid, but for a tzaddik of that stature are considered imperfections on which he must do teshuva.
(As I think is implied from Rav Avigdor Miller that was brought before).

All of this has no relevance to questioning a tzaddik.
There is a difference between questioning and doubting. One must trust a tzaddik and obey his instructions even without understanding (ויאמינו בהשם ובמשה עבדו. אפילו אומר לך על ימין שהו שמאל ועל שמאל שהוא ימין ).

At the same time, of course there is no issue with asking questions and trying to understand. This is the derech of Torah, תורה היא וללמוד אני צריך.
But the Jewish way is naaseh v’nishma – first accepting, then respectfully trying to understand.
