Glenn takes you back to the 4th episode of Infants on Thrones, originally published in September 2012.  It is a surprisingly good Radio Lab styled episode, centering on the narrative structure of “loss and restoration” found both in and out of the Mormon church.  Mike Tannehill also provides some criteria by which one may determine if a church is in apostasy.  (Be careful Mike.  This was recorded pre-essays on LDS.com, buddy!)
