“The eyes of the mind reach the destination before the legs get there,” so say African elders. This speaks of the power of imagining and envisioning of the world that serves everybody better. An ecumenical vision of a just and peaceful Africa attests to this common wisdom. In this sense, theological imagination remains relevant for any ecumenical vision that intends to bring about transformation in the African continent. This essay argues for the importance of theological imagination in advancing any transformative ecumenical program that targets the social sphere in Africa. The reflection on theological imagination in view of ecumenical transformation will then be tested in three social areas of engagement, namely, education, politics, and gender justice. It focuses on the context of Nigeria because of its peculiar turbulent sociopolitical environment and its challenging, but promising, ecumenical opportunity.
