This book, written by a Catholic priest, is a personal encounter with Seventh-day Adventism. It consists of letters exchanged between the author, and an Adventist friend. It captures the deep spirituality of Catholicism and compares it quite objectively with Adventism. I read this book and was stunned at the contrast between the incredibly spiritual depth of Catholic teaching and the message of the Bible on the one hand, and the Adventist attempt to read things into the Bible and bring back the Old Covenant Sabbath on the other hand. Truly one of the best books I have read on the Catholic view of the Sabbath and other Adventist teachings. This is really a MUST for any Catholic interested in Adventism, or any Adventist interested in Catholicism.
