This volume deals with the lived experiences and expressions of Christians in diverse communities across the globe. Christian communities do not live in a vacuum but in complex, diverse social-cultural contexts; within wider communities of different faith and social realities. Power, identity and community are key issues in considering Christian communities in contemporary contexts. Also important is the nature and texture of mission; while a reflection on ‘context’ is a priority in working to improve peoples and communities. The interrelated themes: poverty, suffering and marginalized communities; globalization and the reproduction of hierarchies; Christianity and socio-political action; identity, gender and power; the interface of migration, diaspora and ethnicity; and HIV/AIDS, church and mission, were explored by academics, researchers, church leaders, religious non-governmental organizations, faith-based organizations, as well as policy makers. Such a multidimensional perspective was necessary for critical thinking about how missions is articulated and practiced in contemporary contexts and also towards charting new directions for engagement in Christian Mission in the 21st century.
