A newly-baptized member accepts a calling as the Gospel Doctrine teacher and really shakes things up. Both the Bishopric and the members are caught off guard and blown away her fresh thinking and new approaches. (This usually leads to complaints and hurt feelings and a meeting in the Bishop’s office.)
A fifty-year old life-long member who has been teaching Gospel Doctrine, Seminary, and Sunday School for decades misses insights and doctrinal connections over and over, because he’s still living in ‘tradition.’ He bores his students into complacency and monologues his way through lessons. (This is deemed acceptable and nobody is offended, moved, or edified.)
