Firstly, and as befits the subject matter, this was a beautiful book; from the cover to the binding, even to the thickness and quality of the paper - it's rare that I've enjoyed holding and 'experiencing' a book as much as what it actually contains. I haven't had a look at the accomonaying website but there is a certain symmetry to this also, that a book which speaks of liturgy drawing in all the senses use multiple mediums to express itself - very clever.

I live in the liturgical world and it's brave indeed to write such a book as this since there are as many people with passionate views about liturgy as there are people who experience it! Dr Gillhammer draws upon her considerable expertise to produce an accessible introduction to some broad themes within liturgy that invites the reader into a loving relationship with a way of doing church that some malign as excessively historic or fussy or claim can 'get in the way' of so-called 'real' worship. Liturgists expecting an in-depth history ought to welcome such a passion popular hymn to its beauty and riches.

In some ways it felt like Felicity Cloake takes on liturgy, which is a compliment. I also learnt a lot that I didn't know and have come away desiring to know more. If that was the intention, consider it acheived!

A lovely book about liturgy and expressions of faith in the West over the centuries. Gillhammer shares many works of art, including music, poetry, and visual art. This is accessible for those with little familiarity with the liturgy. It is not an academic book, and while not quite devotional, is written for those with an interest in the spiritual dimensions of the liturgy.

I don't find the subtitle particularly captures the nature of the book. It's not a history of the liturgy or really an "untold story." It details what different parts of the liturgy mean, how feasts and fasts were observed in different places at different times, and what it means to participate in the liturgy throughout time and space (the names of the final two chapters).

I chose this for my Lent reading this year, and it was really wonderful. I finished it in Easter because I wanted to pause at Holy Week for other reading. Since the chapters are themed (Death, Joy, Hope, Grief, et c.) it will be nice to return to those at the appropriate times. I appreciated that Gillhammer did not shy away from the darker parts of the liturgy, nor had a morbid interest in them. Unlike certain scholarly works that have disappointed me recently, Gillhammer writes with the understanding that "people really believe(d) this stuff." Again, it's not a devotional book, but can function that way for a believer like me, yet does not assume the reader shares the beliefs of the communities Gillhammer discusses. The introduction goes through the Apostles' Creed in detail to explain Christian beliefs for the unfamiliar reader.

Overall, I found this very engaging and accessible. If you are familiar with Eleanor Parker's Winters in the World, this is similar to that. Some of Parker's translations are in Light on Darkness. I'd give this to readers who are curious about the liturgy, regardless of their faith, and to Christian readers who want to know what it means to participate in high liturgical traditions. It is a beautifully produced book with high-resolution color images, and clear text on bright white pages.

In Light on Darkness, Cosima Clara Gillhammer delivers a deeply researched and accessible exploration of liturgical history and its significance in shaping religious practice and spiritual life. The book illuminates often overlooked aspects of liturgy, offering readers a nuanced understanding of both the historical and theological dimensions of worship.

Gillhammer approaches her subject with clarity and precision. She traces the development of rituals, texts, and ceremonial forms, highlighting the interplay between tradition, interpretation, and cultural context. The narrative balances scholarly insight with readability, making complex liturgical concepts approachable for both academics and general readers with a keen interest in theology, history, or spiritual practice.

What distinguishes Light on Darkness is its commitment to uncovering “untold” stories moments, practices, and voices that have shaped liturgy but rarely appear in mainstream accounts. The book challenges readers to reconsider assumptions about worship, authority, and ritual while providing a richly detailed account of how liturgy has evolved across centuries.

At 256 pages, the work is comprehensive yet digestible, with careful structure and clear explanations that make it suitable for individual study, group discussion, or classroom use. Scholars, clergy, and spiritually engaged readers alike will find it an enlightening resource that deepens understanding and appreciation of the liturgical tradition.

Cosima Clara Gillhammer has done us all a great favor with this book. It’s a treasure and I highly recommend it, even if you don’t imagine it’s your sort of reading. As a review of ancient and medieval Catholic liturgy and its influence on art and culture, it’s a surprising page turner, and beautifully illustrated. I finished it in two days and enthusiastically pressed it on my wife, who immediately sent a copy to a friend.

Gillhammer, an Oxford scholar, assumes her readers know little about Christianity, and that what they think they know is probably mistaken. This may be a fair assumption for a popular audience today, but it briefly made me feel like a relict. Catholic Christians still exist, after all, and almost everything Gillhammer describes is still a part of our life at Holy Rosary Catholic Church, the Dominican parish and priory in Portland, Oregon, where I am grateful to be numbered a parishioner.

My uneasy feelings didn’t last long. Gillhammer navigates the shoals comfortably and talks down to no one. I don’t know what her religious background may be, but she accepts her subject on its own terms, and she writes like a believer rather than an anthropologist conducting forensic analysis. Her book is so successful because in the end she provides something more than just a review of history, art, and culture. In a fresh way, she communicates the transformative and paradoxical beauty of Christ’s gospel.

You don’t need to be religious to enjoy Cosima Clara Gillhammer’s book Light on Darkness: The Untold Story of the Liturgy, you just need to exist in a dominant culture shaped by centuries of Christianity. Which, if you’re reading this, you probably do.

It provides a rich thematic sampling of liturgical writings and practices, investigating their reflections of—and influences on—how we experience such things as joy and grief, suffering and love, the marking of time, and the dramatic sacralization of spaces.
