This never developed. There are others who have the titles of leadership within the Messianic Communities, however, nobody wields the authority and power that Spriggs does. Since Spriggs is the source of new doctrines and the standard which measures the truth of any other teachings his influence is singular and absolute. Sociologically, the group has become more controlling over the years and more theologically deviant. A large part of the reason for this is the extreme isolation of the group.
People live in community and look and behave alike.
They are also cut off from outside intellectual stimulation and challenge. What information is fed to the average Communities member is thoroughly filtered through the narrow lens of Spriggs' construct of reality. This is not to say that he personally reviews every piece of disseminated literature. This appears to be Phariseeism. The Gospel of Jesus Christ should set a person free.
