I can see the importance of אמונת חכמים faith in the wise. even though the verse that is used most often for this is ככל אשר יורוך''you must listen to all they command you'', still it is often taken for granted that this refers to the  stupid religious teachers of this generation. As opposed to this the verse refers to when a doubt in law comes up then one goes to the Sanhedrin which is formed of people with genuine semicha /ordination. but authentic ordination ceased during the middle of the Talmudic period.
