In this simple, beautifully written book Rowan Williams explores four essential components of the Christian life: baptism, Bible, Eucharist, and prayer. Despite huge differences in Christian thinking and practice both today and in past centuries, he says, these four basic elements have remained constant and indispensable for the majority of those who call themselves Christians. In accessible, pastoral terms Williams discusses the meaning and practice of baptism, the Bible, the Eucharist, and prayer, inviting readers to really think through the Christian faith and how to live it out. Questions for reflection and discussion at the end of each chapter help readers to dig deeper and apply Williams' insights to their own lives.
