The Body of Ordinary Believers Carries the Expansion of the Church
Two sources separated by ninety years make the same wager: the spread of the faith rests on ordinary believers, and professional missionaries play only a supporting part. Roland Allen built The Spontaneous Expansion of the Church on the conviction that the gospel travels through the whole body of new believers who hand on what they have received, and that the missionary’s task is to train locals to take over rather than to run the work himself. Trousdale and Sunshine reach the same conclusion in The Kingdom Unleashed, where the disciple-making movements transforming the Global South run on common believers obeying and reproducing rather than on a clergy class.
The convergence reinforces the vault’s definition that a movement is a self-sustaining chain reaction of ordinary people. Allen supplies the older theological ground and Trousdale supplies the contemporary field evidence, so the claim no longer rests on either a single classic or a single dataset. Both authors treat dependence on professionals as the very thing that stalls expansion, which connects this idea to the Disciple Making Movement insistence that every disciple makes disciples.
The shared logic also explains why both writers distrust importing a paid foreign workforce. If expansion is carried by the body, then a structure that reserves the work for specialists starves the engine. Allen pressed this through his three-self argument, and Trousdale presses it through movement practice.
