''Christians in the Twenty-First Century'' examines Christianity as it is understood and practised both by active followers and those who regard themselves as Christian. The book opens with an examination of key Christian concepts - the Bible, the Creeds, the Church and the sacraments - and the major traditions of Roman Catholicism, Eastern Orthodoxy and Protestantism as well as more recent movements. The book continues with an analysis of the challenges presented by the rise of science, new approaches to biblical scholarship, the rise of fundamentalist movements, the ordination of women, secularization, the interfaith movement, and the impact of the electronic revolution.
