Diaspora missiology is emerging in some evangelical circles as the new paradigm that would complement traditional missiology. In this article, I will describe and analyze the writings of three first generation Cuban-American theologians and their understanding of how to construct theology in diaspora. First, I will present the multiple origins of the Latino/a population. Second, the metaphor of the Promised Land will be described and assessed though the lens of the prosperity gospel. Third, the writings of Ada María Isasi-Díaz, Justo González, and Fernando Segovia on theology in the diaspora will be described and analyzed. Finally, a Latino/a missiology of social engagement will emerge out of the three theologians discussed.
