Faith, at its heart, involves trust―even when complete certainty is absent. Scrupulosity, by contrast, demands answers to doubts that were never real to begin with. Rev. Thomas M. Santa, CSsR.’s Ten Commandments for the Scrupulous (2013) has long served as a practical guide and source of relief for those suffering from scrupulosity. This pamphlet revisits Fr. Santa’s commandments through the contemporary psychological lens of Inference-Based Cognitive Behavioral Therapy (I-CBT) as a way of continuing his legacy of compassionate guidance. This pamphlet aims to help people distinguish between genuine moral reflection and OCD’s false alarms, freeing them to live and practice their faith with confidence, compassion, and peace. Frederick Aardema, PhD, is a clinical psychologist and co-creator of Inference-based Cognitive-Behavioral Therapy (I-CBT), an innovative approach to treating Obsessive-Compulsive Disorder (OCD). Thomas M. Santa, CSsR, the priest director of the Scrupulous Anonymous newsletter, has ministered to people with scrupulosity for more than twenty years. He is an associate faculty member and former director of the Redemptorist Renewal Center in Tucson, Arizona. He has also served as pastor of St. Michael Parish in Old Town, Chicago, and as President/Publisher of Liguori Publications.
