“Lex orandi, lex credendi (Latin loosely translated as “the law of praying [is] the law of believing”) is a motto in Christian tradition, which means that it is prayer which leads to belief, or that it is liturgy which leads to theology. It refers to the relationship between worship and belief, and is an ancient Christian principle which provided a measure for developing the ancient Christian creeds, the canon of scripture and other doctrinal matters based on the prayer texts of the Church, that is, the Church’s liturgy.”
