It is my understanding that Emunas Chachomim means trusting that the Chachomim are being honest and doing their best to preserve the mesora and apply the halacha. In other words, to say that the “rabbis” are just trying to control the people, or “where there is a rabbinic will there is a halachic way” is a failure of emunas chachomim. Similarly if someone says that Chazal made up the story of the pach shemen, chalila, in order to give the Chanukah story a religious spin (like some historians claim), that is a failure of Emunas Chachomim.
I have unfortunately met people who lack Emunas Chachomim and they are always coming up with conspiracy theories as to why the Gedolim are doing X or Y, or why Chazal said X or Y. But learning up a sugya in halacha or hashkafa and happening to conclude differently than the majority of the Gedolim of nowadays is a good thing not a bad thing.
