Priests take a vow of obedience, so they are in a hard place.
The RCC has faced several bouts of severe corruption during its 2,000+ year history. Perhaps it is time that the laity become more involved in its administration. We need to rethink the amount of power— which is not the same thing as religious authority— that rests in the hands of the Curia.
Or maybe they are all cut from the same cloth...some may be more on the edge of the cloth, but all from the same cloth.
Only the orders take that vow. However there is such a thing as loyalty and duty without a specific vow.
