Larry Christenson, a leader in the Charimatic Renewal, reviews the polity of the Catholic Apostolic Church, an earlier group (also called the Irvingites ca: 1835 to 1901) which also experienced the charisms (glossolalia, etc.). Christenson finds the model of the older group a good match for the Renewal. I'm too far from this mind set now to recommend this book, but, if you're interested in new religious movements and how they are similar and dissimilar, you might find comparing the Catholic Apostolic Church to the Charismatic Renewal to be interesting.
