The Rule of St David: A Rule of Life for the Order of St David Gwnewch y pethau bychain. Do the little things. On the eve of his death in the year 589, Dewi Sant gathered his monks and spoke his final words: Be joyful, keep the faith, and do the little things that you have heard and seen me do. Fifteen centuries later, those seven words remain the most complete summary of Celtic Christian spirituality ever given. They are not a farewell. They are a rule of life in miniature. This volume contains two things: an extended meditation on those words, and the Rule they inspired. Three introductory essays open the book, each devoted to one of St David's three commands. Drawing on the Desert Fathers, the Celtic hagiographies, the Benedictine tradition, and the great teachers of Christian spirituality from Augustine to Thérèse of Lisieux, these essays explore what it means to be genuinely joyful in a world saturated with anxiety, to keep faith through the long and unglamorous middle of a Christian life, and to find holiness not in extraordinary acts but in the faithful performance of ordinary things. They are theology written for practice, and formation written for the heart. The Rule of St David follows. Compact but comprehensive, arranged in five parts across fifteen chapters and thirty-six articles, it is the founding document of the Order of St David: a secular institute of consecrated life rooted in the twin streams of Celtic and Benedictine spirituality. Its three vows, Rootedness, Wholehearted Devotion, and Faithful Service, give canonical form to everything the introductory essays have explored. This is not a document to be admired. It is a path to be walked. Byddwch lawen. Cadwch y ffydd. Gwnewch y pethau bychain. Be joyful. Keep the faith. Do the little things.
