The Anglican Catholic Church holds the Affirmation of St Louis as its founding document from which it seeks to express its identity as part of the One, Holy, Catholic and Apostolic Church of the Nicene Creed. The Affirmation contains a section on moral principles which stands in opposition to the moral theology of the Anglican Communion from which the Continuing Anglican Movement emerged in 1978. The purpose of this book is to use the Catholic Principles that lie at the heart of the doctrine of the Catholic Church to investigate the moral content of the Affirmation, to describe the moral theology therefrom and to examine the foundations and ramifications for the Anglican Catholic Church in holding these principles and how it continues to seek continuity with those with whom it shares an ecclesial heritage.
