The most important lesson to learn about devil’s advocacy isn’t the need for a formal contrarian position; it’s the need to interpret criticism as a noble function. An effective promotor fidei is not a token argumentative smarty-pants; it’s someone who deeply respects the Catholic Church and is trying to defend the faith by surfacing contrary arguments in situations where skepticism is unlikely to surface naturally. (Who wants to argue against someone who’s lived a life so admirable that they merit consideration as a saint?)
