This ancient Latin axiom is quoted often. The phrase means, “The law of praying is the law of believing,” or put another way, it means the law of prayer (“the way we worship”), and the law of belief (“what we believe”).
This Latin phrase addresses the centrality of worship in the life, identity and mission of the Church.
The statement is sometimes extended and written as, “lex orandi, lex credendi, lex vivendi”, further deepening the implications of this truth—how we worship reflects what we believe and determines how we will live.
The law of prayer or worship is the law of life. Or, even more popularly rendered, as we worship, so will we live . . . and as we worship, so will we become! (8:12)
