Decentralized
This willingness to have the texts copied meant that at no time during the history of their transmission did any one person, any group, any ecclesiastical structure control the books’ content, individually or corporately. Despite mythological traditions to the contrary, the early church, as a persecuted minority, was not under the control of a single man or group of men, and the copying of manuscripts was done freely, without centralized control.
