Lex Orandi, Lex Credendi: How the liturgy shaped the worldview of early Christians

A 2004 paper written for the History of Christian Doctrine, exploring the extent to which ancient liturgies both express early Christian theology, and also were instrumental in shaping the worldview of early Christians. This paper looks at extant Christian liturgical materials used around the ancient world up to circa 400 CE as evidence of early Christian belief and theological formation.

1. Lex Orandi, Lex Credendi: The role of liturgy in worldview formation

How are the words that we pray and say and sing in worship connected to what we believe?  How did the worship of early Christians shape their beliefs and actions?  The ancient Latin tagline "Lex Orandi, Lex Credendi" (literally: the law of prayer is the law of belief) has a lot to say about this.  This maxim, first popularized by Prosper of Aquitaine between 435 and 442 (Wainwright, 224-225), tells us that how and what we pray shapes how we believe and hence, how we live.  The converse is true as well.  What we believe will eventually be reflected in our prayers, our worship, and our lifestyle.  This means that our worldview, what it means to think and believe as a Christian, is somehow implicit in our liturgy and prayer life.  That is true now, it was true for Prosper, and it was true for the early Church as well.  What it means to be distinctively Christian, and believe as a Christian, should be available to everyone in our worship, at least in theory.

Chasing Falsifiability down the Rabbit Hole to Transcendence

In my Philosophy of Religion class the other day, a student brought up Karl Popper’s principle of “falsifiability” as a criteria for whether a knowledge claim is valid. The way that my student put it: A claim that is empirically sensible is thus falsifiable (it can be refuted by empirical observation), and thus counts as real knowledge. But knowledge claims that are not empirically falsifiable— such as claims about God, ethical value, aesthetic value— do not count as the same kind of knowledge. Perhaps they are a lesser, derivative kind of knowledge. But they are not the kind of absolutely true knowledge one would want to build their world view upon, because they cannot be empirically falsified. And thus, while God, might be an optional or extra belief added onto a scientific worldview, God could never be essential to a worldview, or even a necessary explanatory hypothesis for the nature of Reality, because the idea of God cannot be falsified scientifically.
