This book invites us into 'frontier-crossing' in three parts: The first is dedicated to the memory of a theological educator who influenced students and pastors in contextualising theology, liberating them from western-only concepts, building bridges over racial and cultural divides, and encouraging learner-centred dialogical education. The second shares with us some of his own writings, especially on pastoral training and intercultural learning in Birmingham (UK) and Umlazi, Durban, rendering culture a starting point for church and mission. The third, the 'Legacy', raises awareness of various contemporary issues such as African Christianity as a new religion, the significance of new religious movements, especially African Indigenous Churches, the impact of the African Diaspora on Europe, liberating theological education, listening to women's voices, diasporic identity as hybridity, and interreligious dialogue. It may serve as a textbook for transcending barriers, not only in content but also in critical methodology.
