Book excerpt: To celebrate the 10th anniversary of Anglicanorum Coetibus, Tracey Rowland gathers together leading voices to examine the issue of the Anglican Patrimony and its relevance for Christians today. The Anglicanorum Coetibus is the 2009 papal decree which established the Anglican Ordinariate within the Catholic Church, and this volume examines the longstanding effects of this cultural decree. Rowland introduces different aspects of the culture of Anglicanism, explains the concept of an Ordinariate within the context of ecumenical theory, and examines aspects of Anglican liturgical theology and pastoral life.
