The 9 Laws of Liturgy, Especially in Advent

Liturgy matters.

Throughout Christian history, a majority of Christians have used a liturgy in the sense of a set form of words, actions and rituals, as opposed to a free-form, open-ended kind of worship. This does not mean non-liturgical churches are totally disorganized — they often plan their services according to familiar patterns and models. But they do not follow the precise sequence of texts, passages or actions, which they regard as too formal and constricting. Still today, though, liturgical churches overwhelmingly represent the Christian norm. Once we take account of Catholics, Orthodox, Anglicans and Lutherans, that would probably represent three quarters of all Christians worldwide. Recently too, even historically non-liturgical churches have selectively adopted liturgical forms, in what some call an “ancient futures” movement.

Liturgy is a vast topic, which is the subject of very wide-ranging scholarship. Here, though, let me just suggest briefly why it is so central to church life, and never more so than in a season like Advent.

In its origins, the Greek word leitourgia meant “people’s work,” better translated as something like “public service” or “public duty.” In common usage, the word also refers to the liturgy, namely the particular service that culminates in the Eucharist or Holy Communion. A Catholic or Anglican liturgy includes various parts that together form a logical sequence and a unified whole, like a symphony. These include, for instance, such set-pieces as the Kyrie Eleison, the Gloria, the Creed, the Sanctus and the Agnus Dei (Lamb of God).

So what does liturgy do, and why does it still exert its astonishing appeal after two millennia? Without any attempt to be definitive, let me offer my nine laws of liturgy:

1. Liturgy takes us out and puts us in

Liturgy takes us out of the regular world and returns us to a sacred moment or sacred time. It is a way of putting us in touch with a particular reality, of converging and conforming our world with the supernatural. Liturgy thus explains why we are here but at the same time also places us somewhere else.

Paths cross here.

2. Liturgy unites, making many one

The liturgy organizes and moves people through a common sense of participation, of shared action. It unites us and makes us a common body. We say and do things in the same way, we speak the same words and hear the same things and express agreement to them. It is communal action. To use the Anglican phrase, we all share in common (i.e., communal) prayer.

3. That unity crosses boundaries of time and space

The fact that liturgy is fixed means that anywhere you go in the world, you will hear the same words and the same patterns. Services are not “dealer’s choice” in which any words or forms are permissible, and they don’t depend on the whims of particular leaders. That is also why we use the formal language appropriate to solemn things. Historic form and language are used to consecrate time.

When we share in a liturgy today, we are doing essentially the same thing that countless others were doing a hundred or a thousand years ago. Liturgy thus creates community and continuity with past and present, proclaiming a link with past and future. We see this, for example, when we repeat ancient Greek terms like Kyrie Eleison.

Language speaks us.

4. Liturgy uses action to declare and reinforce common belief

The old phrase says lex orandi,lex credendi, “the law of prayer is the law of belief” — roughly, show me how you worship and I’ll know what you believe. Not just in its verbal statements, a Eucharist proclaims the Church’s basic teachings through what the participants say and do. Every moment, it teaches the idea of incarnation.

5. Liturgy tells stories in ways that make us live them

People make sense of the world through storytelling, which allow us to build and shape memory. We tell stories in different ways, sometimes through words but also through action. Ritual and behavior are singularly effective ways of telling a story. A liturgy like the Christian Eucharist also tells a story in order to preserve and pass on the church’s memory.

6. Liturgy uses performance to tell stories

Without embarrassment, I use the theatrical word “performance.” As in any theatrical performance, liturgy uses cues to move to different phases — some moments and events signify beginnings and endings, calling you to be onstage. Like any play too there are ups and downs, an ascent to a climax and then a return to something like normal. In a Eucharist particularly, we share different actions and experiences appropriate to different phases of the event. And there are clearly distinct portions, different “acts.”

7. Liturgy unites and binds things that otherwise are wholly separate

Liturgy is sacramental, in that it uses many different kinds of material symbol and object to carry spiritual truths. It also unites the mind and the bodily senses. It is not just rational and book-centered. It uses physical beauty as a means of presenting and reinforcing truth. Readings and texts are integrated into the larger “performance,” with its changing moods and lessons.

8. Liturgy consecrates time — or else time consecrates liturgy

Stories and performances all have their appropriate times and settings. Liturgical actions, likewise, depend wholly on the cycles of the church year. Participating in liturgy means we share in this cycle, we join its beginnings and share the route to its end. Much of this journey involves non-literate means, including seasonally appropriate colors and lights.

Finally, and shockingly:

9. Liturgy allows earth to become heaven, however briefly

The Bible repeatedly describes liturgical actions, on Earth and in heaven, at God’s court. We see this especially in books like Isaiah and Revelation. In turn, those scriptural passages have had a huge impact on the actual practice and language of earthly churches. In a prayer like the Sanctus, the “Holy,” humans celebrate with angels, breaking down divisions between natural and supernatural, Earth and heaven. That is the central theme of the Eucharist.

And those are my nine laws. Another person might have three or 300, and they would probably be just as valid.
