My book was originally inspired by the COVID-19 pandemic, but as the interview indicates expanded as a Catholic response to emergencies in general, such as accidents, catastrophic illnesses. As you say, we all live with the possibility of dying without the sacraments. In my book I attempt to show the inextricable link between specific doctrines and their associated devotions. My own experience has shown me that the traditional explication of doctrine is life-changing and life-enriching. In this way my book is different to a manual of devotions.
