Alan Jacobs, quoted in the same report:

Very few churches overall are really interested in Christian formation. They know that if they demand a level of Christian formation of people, if they demand spiritual disciplines from them, if they demand serious study from them… they’re afraid that if they do that then the people will not be entertained and will go somewhere where they are entertained and where they are affirmed and where they’re not asked to think hard thoughts and practice difficult disciplines.
