Worship does truth. The ancient church captured how worship does truth in the phrase lex orandi; lex credendi; est. . . . [One] way to state the essence of this Latin phrase is to say, “Show me how you worship and I’ll show you what you believe.” If how we worship shapes what we believe, then it is imperative that we pay attention to how we worship. If worship is shaped by culture, it will result in a culturally conditioned faith. If worship is shaped by narcissism, it will result in a me-oriented consumer faith.
