Through a decoloniality framework that emerges from the embodied and embedded theological experience of the ex-colonised religio-cultural situation, this research explores how a reimagining ecumenical theology in Africa can support and promote Aspiration Five of Agenda 2063. The Aspiration focuses on building an Africa with a strong cultural identity, common heritage, values and ethics. It speaks of the integrity of African diversity in culture, language, and religions as a basis of strength that contributes to cultivating a robust sense of identity and pride towards socio-political and economic development on the continent. Through an exploratory methodological design, the research argues for a more nuanced and broad understanding of African ecumenical theology that resonates with African culture, heritage, and values. Such ecumenical theological engagements stand in deep historical recognition and continuation of the contributions of African theologians grappling with the issues of cultural identity, heritage, and values. The research proposed that reimagining ecumenical theology to promote Aspiration Five of Agenda 2063 should include memory, resistance, and creativity. Strategies for promoting Agenda 2063 include ecumenical theological education, ecumenical gatherings, and intentional collaboration with religious, non-religious, and governmental organisations working to implement Agenda 2063. The AU Agenda 2063 must be communicated harmoniously with the church’s social, cultural, and theological teachings. Thus, theological training must be relevant to Agenda 2063, whose objective is the flourishing and well-being of the continent.
