This model seems a poor one, and to my thinking is infantilising. It is common elsewhere in hierarchical structures. Modern corporate events are often over-managed, with speakers (keynote ones, no less) and controlled questions. There is no real conversation - which is always horizontal in nature. At such events communication tends only to the vertical. I have witnessed some cathedral discussion events where people in the 'audience' are invited to write out a question and hand it to a frock-coated flunky who conveys it to someone who then decides whether or not it is to be asked. And not asked by the questioner, but by a measured intermediary. The practical need to best manage large events cannot be disputed, but when does this verge into control, even repression? These are not conversations between adults, seeking to better understand something (discernment). They are staged events.
Alan Ecclestone thought it vitally important that the church (the gathered body of Christ's followers) should meet outside the liturgy and that its members should be enabled to speak and be listened to. He realised this might take time, as people found their voices and also learned to truly listen to one another. It is worth the effort. This is being the local Church. Local and at once universal.
