The hierarchy/clergy who heap all the burdens on the people are the bigots.  They consider themselves intellectually and morally superior to the "little people" [Benedict XVI's term for the laity].  Therefore, the hierarchy/clergy act as if they are higher in the spiritual order as well.  A good pastor puts the higher expectation upon himself, not his people.  THEY will observe him---and be inspired to try to be the best people that God created them to be.
