Liturgy is concerned with the worship of God. Yet in spite of that - some might say because of that - it is necessary to have rules. It is sometimes mistakenly thought that these rules are archaic and therefore irrevelant; in fact the rules and their interpretation have changed considerably in recent years, so much so that there is now widespread concern among the clergy and church administrators about the degree to which Liturgical Law is being correctly understood and applied.This book has a straight forward aim which is to describe and analyse a wide range of Ecclesiastical Law topics which are scarcely dealt with in other books on Church Law and Ecclesiastical Law. As such it provides not merely a statement of legal principles but also a discussion in-depth of the relevant law and its developments. The style is precise and easy to read. The authorities and foot-notes are comprehensive. Arguably it presents the most comprehensive coverage of Ecclesiastical Law published in modern times.
