Book excerpt: In this new three-part book series, Avis tackles a series of issues relevant to Anglicanism in the current day. The first book, In Search of Authority, seeks to examine Anglican Theology in relation to questions of authority. Anglican theology has been a hotbed of debate about the issue of authority since the Reformation. What do we really appeal to when attempting to decide matters of doctrine, worship, ministry or ethics? The debate is very much alive today, between Evangelical, Liberal and Catholic Anglicans around the world. This book focuses on the understanding of authority in Anglican theology.
