All the preceding chapters have built up to this final and perhaps most important chapter. As the title of this chapter suggests, the goal is to present a clear answer to the question, “What does it mean to be a developing Christian in today's world?” Although there are many pressing problems in today's world that a developing Christian is obliged to confront, five key categories of problems are discussed: (1) poverty and income equality, (2) the immigrant and refugee crisis, (3) the many faces of violence, (4) the many faces of bigotry, and (5) the problems caused by power and oppression. In each case, consideration is given to explaining why developing Christians should consider the problem to be intolerable, why the problem exists, and potential solutions to them. To make the arguments in this book even more concrete and practical, the life of an exemplary modern Christian (Dorothy Day) is discussed and linked to the present and prior chapters. The chapter ends with a plea for dialog, unity, and a call to social action.
