Should one follow a Rabbi who creates a chsllulel Hashem. Should such a Rabbi resign positions of importance or ask for public teshuvha.
This is extremely vague. What is the definition of a fallen Rabbi in this article?? The passuk says אין צדיק בארץ אשר לא יחטא, unfortunately, nobody is perfect, Moshe Rabbenu also sinned on his lofty level and Hashem said that he caused a chillul Hashem. Of course, some sins are more severe than others, some cause more chillul Hashem than others and hopefully everyone does teshuva swiftly after falling too. To blanketly say that a Rabbi must be like an angel otherwise we can’t learn his Torah leaves us in the dark.
