Lex orandi; lex credendi: the law of prayer is the law of belief. How we worship signals exactly what is most important in our lives. Watch Christians worship and you should be able to discern what they believe. Advancing this axiom, The Book of Common Prayer occupies a central place in worship in the Anglican Way. This homily, offered by Fr. John on Trinity 21, November 9, 2014, is part 1 of a series of reflections on themes from the prayer book that inform our spiritual habits and development.
