What is the history and nature of Opus Dei, particularly its cult-like nature and its obsession with secrecy, the worst being teaching children to conceal their involvement from their parents? One of the most shocking revelations is the story of how Opus Dei has infiltrated its sympathisers into the Vatican and subverted the integrity of the process by which the claim to sainthood of people is assessed - for example abolishing the 'devil's advocate'. If this process were carried out properly testimonies like Maria Carmen del Tapia (see her excellent book. Beyond the Threshold) would be properly taken into account. Escriva is not a saint. This book is a valuable contribution to public information about what is clearly a harmful organisation - the website of the Opus Dei Awareness Network ODAN is worth consulting.
