Chapter 6 considers how pietistic idealism shapes the evolution of the orphan care movement in tension with other internal and external pressures. First, it shows that CAFO and the movement itself have already evolved considerably since the movement’s inception in the early 2000s. This evolution has followed a common pattern of religious groups and movements—they have grown in numbers, diversified, professionalized, and gradually become more accommodating to secular society and the state. While these changes have moved the movement toward greater strategic effectiveness in several regards, the chapter proposes this is actually in spite of pietistic idealism, not because of it. Drawing on interviews with movement leaders, the chapter shows that pietistic idealism is fundamentally conservative in that it values preservation over innovation and progress. Thus, while movement leaders would affirm that tactical adjustments are necessary and good for improving strategic effectiveness, effectiveness is not the ultimate goal; obedience is. Those most committed to pietistic idealism will always be more concerned with keeping the movement focused on the main thing—glorifying God and communicating the gospel, even if it means neglecting strategic effectiveness. Evangelical efforts influenced by pietistic idealism will thus be fundamentally self-limiting.
