Post-400 AD Christianity is a two-fold history of reformation of theology and praxis. Multitudes of books have been written on the reformation and restoration of apostolic doctrine, but few have even considered the restoration of apostolic ecclesiology. The reason for this: it contradicts the wealth and power of the church, so much so that the church persecuted anyone who even tried to live it out by themselves. - John P. Harrigan, Biblical Praxis of Missions
