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.
As a professor of missions, I often hear people say "you can be missionary right in your own neighborhood." As with any academic field, it's important to get the terms clear. While you can be an evangelist in your own neighborhood, "missionary" and "missions" should not be confused with "evangelism" or "discipleship."
Missions is cross-cultural discipleship, so some very important work that we do as the church is NOT missions. Drawing a boundary does mean excluding some work from the definition of missions (thought such work may be missional and strategic for the church). Consider the following true examples from my students:
Sharon, from the USA, teaches English in Thailand. She was not sent by her church, is not under a mission agency, and receives a salary from her university. While she is working cross-cultural, she does not see herself as a missionary because her presence in Thailand is not particularly about making disciples
Miguel, from the Philippines, is studying theology and missions in the USA, but plans to plant churches among his own ethnic group in the Philippines. He considers himself a church planter, but not a missionary.
Carmen, from the USA, is financially supported by members of her own church to do the bookkeeping for a mission organization in West Africa. She does not particularly “teach them to obey all Jesus has commanded,” but her mission organization does have an overall plan to make disciples. Carmen sees herself as a missionary because of her important role in an organization that is doing missions.
If a cross cultural worker digs wells but has no overall plan for “teaching them to obey all Jesus commanded,” then while it is obeying the first commandment to manage the earth for the flourishing of humankind, it is not part of the narrower aspect of the churches mission to make disciples across cultures. And in all fairness, I must add, if an organization plants churches and hands out tracks, but is not actually “teaching them to obey all Jesus has commanded,” then it, too, is not actually doing missions.
Of course, in our day-to-day experience, the set of activities which are involved in making disciples is fuzzy. Healthcare can be done in a way that teaches people to obey Jesus, or it can be done without touching on issues of discipleship. A Christian could work cross-culturally in such a way that she makes disciples in her secular workplace, or she could hide her light under a bushel. By defining missions narrowly as cross-cultural discipleship, I am not as much excluding certain activities as I am focusing on the setting (does it cross cultural boundaries) and strategy (does it make disciples) that drives those activities.
The activities (methods) and purpose seem to fall in three general categories. The most obvious is witness. Some “teach them to obey all Jesus commanded” by planting churches, teaching in international seminaries, exorcising demons, and preaching to crowds at college campuses. But in 2016 we reached the threshold where more than 50% of people who call themselves missionaries say their primary activity is not witness, but service, development, healthcare, or cultural production through the arts. A second category of missionary methods includes engagement in public life. And a third we may label as “cultural production.” The below shows how these categories fit together in the bigger picture of making disciples across cultures.
As Y2K approached (remember that?) Louis Bush popularized the idea of prioritizing missionary efforts in the 10-40 window: latitudes 10 to 40 North, where the world's majority of Muslims, Hindus and Buddhists live. At that time missionary boards began focusing on Unreached People groups (as defined by David Barrett's Encyclopedia of World Christianity and popularized in the Joshua Project). The idea was that if fewer than 2% of a people group were evangelical Christians, there would be no indigenous church strong enough to evangelize its own people, so missionary efforts would be necessary. This push for missions among the least-reached in Asia (that's where the 10-40 window is) not only helped prioritize sending-country efforts, but it ensured that other parts of the world could become self-supporting, as expatriate leadership and resources were pulled out and
