Shawn of Rerum Novarum has done an excellent series of posts on obedience.
One of my favorite stories on obedience is that of Fr. Regis Scanlon is where he was told by his superior that it was okay to dissent from the Pope and that he didn’t have to be obedient to him. The next time his superior told him to do something he told him “I dissent from you.” Normally those that teach dissent are not okay with people dissenting from them.
