In 1974, Ralph Winter wrote a paradigm-changing article, “The Two Structures of God's Redemptive Mission,” which affected the way many evangelical mission leaders view the role of the local church and the mission agency in world evangelization. What began as a historical observation, primarily, has developed into a theological doctrine which advocates theological legitimacy for mission agencies. Using Winter's document as a beginning point for discussion, this article analyzes and rejects the doctrine of sodalities as being another expression of the universal church. Instead of arguing for the acceptance of mission agencies (independent or demoninational) from a biblical basis, the author maintains that agencies should be accepted and utilized on a pragmatic basis by congregations.
