Thomas O'Loughlin writes about liturgy as a priest who knows what it is like to be a member of the congregation, as a historian and biblical scholar with a lively sense of liturgical action, and as a keen observer of life and worship. In this short book, he offers profound insights in a disarmingly colloquial argument, illustrated with recognizable scenes from inside and outside the church. Good liturgy, he tells us, says what it does and does what it says. The ten principles that expand this essential claim constitute a guide to excellent and joyful liturgical life, and a barometer for testing its truth and integrity.Bridget Nichols, Lecturer in Anglicanism and Liturgy, Church of Ireland Theological Institute, Dublin This book has a lot to offer for both personal reflection on liturgy, as well as shared reflection and spiritual growth for liturgy committees, priests, deacons, musicians and ministers of the various parish ministries. Anyone with a passion for the liturgy will appreciate the opportunity to engage with the thoughts that O'Loughlin shares in this book.Liturgy
