In the 1950s, a conversation among a handful of American graduate students considering the place of Mennonites in the modern world blossomed into a published forum, CONCERN: A Pamphlet Series for Questions of Christian Renewal. The CONCERN writings here consider the global, missional, experiential, contextualized realities of such a ""place,"" past and present. The writings explore the role of culture and context in the church's mission, lived faith, and theological articulation through various avenues of approach: the global church and the ecumenical movement, Christendom's legacy of colonialism and cultural accommodation, critique of rigid and outdated ecclesial structures and forms, the complexities of the unavoidably enculturated nature of faith as proclaimed and lived. Two contemporary responses offer postcolonial critique and development, demonstrating that such topics continue to be of critical concern in today's globally interconnected yet fragmented and divided world.
