Joshua plays a key role in ACTEA’s research, consultations, and publications, including editing the ACTEA Series and co-managing the journal African Christian Theology. Originally from the U.S., he has mission experience in India and Papua New Guinea, has taught in South Africa (2000–2001), and has lived in Kenya since 2007. There, he’s worked as a curriculum developer and theological educator, primarily serving the Maasai and Turkana communities. His teaching experience spans Chemistry, Old Testament, Christian History, Missions Studies, and World Religions. Passionate about Christian history, particularly in Africa, he has published extensively on related topics, missiology, New Testament exegesis, and African Christian theology. He serves on several journal peer review boards, including Priscilla Papers, and co-founded the “African Christian Theology” Facebook group (unconnected with ACTEA’s journal). He is one of the series editors of African Christian Studies Series (Pickwick Publications), the series editor of Rethinking Church in the 21st Century, and the series editor of the ACTEA Series. He serves on the editorial board of HTS Theological Studies. An ordained minister, he and his wife, Ruth, have six children. They co-authored a text on congregational hermeneutics and homiletics in Maa, which has also been translated into Swahili and Turkana.
