Christianity in Africa: Ancient roots, missions, independent churches, and Pentecostal expansion

Africa is not a late appendix to Christian history. The continent appears in the New Testament world, supplied some of ancient Christianity's most consequential intellectual and ecclesial centers, preserved continuous Christian traditions in Egypt and Ethiopia, sustained medieval Christian kingdoms in Nubia, received and reshaped Catholic and Protestant missions, generated African-initiated churches, and became one of the principal centers of global Pentecostal and charismatic Christianity. This chapter reconstructs that long history from the first century to the present, with particular attention to the nineteenth through twenty-first centuries. It distinguishes ancient continuity from later re-entry, mission transmission from colonial domination, denominational transplantation from African appropriation, schism from reform, and foreign influence from indigenous theological agency. The narrative follows Alexandria and the Coptic tradition; Latin North Africa; Aksum, Ethiopian and Eritrean Tewahedo Christianity; Nubia; the Christian Kingdom of Kongo; Catholic and Protestant mission expansion; Bible translation, schools, medicine, and African clergy; Ethiopianism and ecclesial independence; Zionist, Aladura, Kimbanguist, and other prophetic movements; the East African Revival; classical Pentecostalism; and the rise of neo-Pentecostal, prosperity, deliverance, megachurch, media, and network Christianity. It argues that no single genealogy explains African Christianity. Multiple ancient, mission-founded, revivalist, independent, Pentecostal, and network lineages coexist and continually interact. A Sola Scriptura assessment affirms African Christian agency, vernacular Scripture, evangelism, prayer, spiritual gifts, healing, and accountable contextualization while testing sacramental claims, extra-biblical authority, syncretism, prophecy, prosperity teaching, spiritual warfare, and founder-centered government against the apostolic Scriptures. The chapter concludes by showing how Africa's demographic and missionary weight now reshapes global Christianity and prepares the focused national genealogy of Rwanda.
