Once people groups are identified, strategists begin to catalog these groups in terms of evangelistic response and need, for the purposes prayer (Johnstone, 2001). And mission organizations begin to direct mission resources to the fields (i.e., people groups) 1) that were seen as “ripe” (receptive); or 2) to those where no work has been done. If it were not for the concept of people groups, mission mobilizers would not have come to emphasize unreached people groups in the 1990s. Beginning with the world’s 7000 distinct languages (P. Lewis, Simons, & Fennig, 2013), the Joshua project took into account features such as religion, and ethnicity, (“Global Statistics,” n.d.) to arrive at a list of over 16,000 people groups.
Missiologists (Bush, 2013) have, understandably, connected the concept of ethnolinguistic people groups to the use of ethne in the New Testament. For example, they contend that Matthew 28:19 means “Make disciples of all people groups.” This argument is fraught with difficulties:
Think of the difficulties in interpreting ethne as ethnic groups: Is the child of an African-American father and Korean mother a member of a distinct ethne—yet another ethne that must be evangelized and will be included in the “all cultures in heaven” list? Would reaching a Korean-African American be considered as one new ethne or two or three ethne? What about people like Tiger Woods—“Cabalasians” who have numerous ethnicities in their background (as in fact, we all do)? Are they included as a distinct ethne? Are Caucasian Americans in the twenty-first century—with the innumerable combinations of Scandinavian, Mediterranean, Eastern European ancestry—to be understood as a single ethne? If we extend ethne to mean “however people identify themselves ethnically” or “all possible ethnic permutations” then we are left with so many possibilities that we may as well just say “all people.” In fact, that is exactly what many theologians conclude: We must interpret “every tribe and nation” as a metaphor for many people from all over the world. (Nehrbass, 2016, p. 71)
The model of people groups has now been amended to include seventeen major “affinity blocs”, including the Arab world, East Asians, Eurasians, Jews, Malay, North Americans, Pacific Islanders, etc. As affinity blocs are highly reductive and do not take into account these major differences in ethnicity, language or religion, the concept may appear to be a regression from “people groups.” However, affinity blocs are also a missiological application of the homogenous unit principle: Mission strategies within the Arab world will be tailored differently than they will among North Americans or East Asians.
The concept of people groups, combined with the 20th century push for “evangelization in this generation” led to the discourse of unreached people groups. Once these unreached people groups could be identified, mission mobilizers suggested adopting people groups, especially in a geographic region missiologists called the 10/40 window.
