F. Evangelism is a reinforcing process. There are four basic ways for the gospel to enter a culture; all reflect a form of cross-cultural incarnation and contextualization. Donald McGavran, a missionary executive in India, noticed that the gospel spread more effectively within a particular cultural group; this success in a rigidly prejudiced society led to the formulation of the famous but dated Principle of Homogeneity: “Men like to become Christians without crossing racial, linguistic or class barriers.” Traditional church growth theory understands that the gospel expands through the relational network which McGavran called “the bridges of God.” This classic missiological strategy focuses on establishing one or more converts within a targeted ethnic group and supporting their indigenous work of evangelizing their own ethnic group through existing relationships in their existing personal networks. Known as a person of peace approach, diffusion of the gospel begins through the conversion of a key person of influence and the gospel then spreads throughout that person’s network of influence, particularly among family relatives.
