Composed on the occasion of the eighth centenary of the Carmelite Rule, historian Patrick McMahon, O. Carm., offers an interesting and in-depth study of its background. He then offers a commentary on the accompanying text in order to answer the question of its suitability for all Carmelites, particularly the laity. He concludes with some interesting reflections on the significance of this inheritance for Christians, and particularly Carmelites, today.
