The New York Times provides us with inspiration in the form of Father James Martin's Op-Ed piece Saints That Weren't. He takes the story of the recently canonized Mother Theodore Guerin as a point of departure. He mines history for further examples, then goes on to say:
"The church's long history of "faithful dissent" offers both hope and perspective to Catholics in our time. It echoes the call of the Second Vatical Council, which, in 1964, declared that expressing opinions "on matters concerning the good of the church" is sometimes an obligation for the faithful."
