This work explores how Christian language alters in various social, cultural, historical and religious contexts. Having delineated the core language of Christianity, David Martin analyses how it mutates in different historical and social contexts, notably: peace and war; the arts - particularly painting and music; the sacred space (the city) and the sacred text (the liturgy); education; and the global situation of Christianity and contemporary secular society - evangelicalism, rational religion, Pentecostalism and Base Communities. Presenting a unique perspective to show how and why Christianity alters according to context, this book should prove insightful and accessible to students, clergy and general readers alike.
