For centuries his name was forgotten. However, St. Jude Thaddeus was perhaps the only one of the apostles who witnessed the life of Jesus from beginning to end, since he was his cousin. The importance of his apostolate contains a series of questions whose answers are not so well known: what happened to the life of this man who spread the word of Jesus? Why is he known as the apostle of impossible causes? Why was tolerance and integration the main premise? What made you try to rescue the role of women in the religious service? Through an emotive and suggestive narrative, Antonio Velasco Piña takes the reader on an initiatory journey that will lead him to the spirit of a man who, from a young age, was committed to the teachings of those who changed the history of humanity. Many of the concerns that our civilization is currently experiencing, such as the integration of all the visions of the world, the preponderance of the role of the female figure in the conception of the world and, above all, tolerance as a means of coexistence, are not recent: There was someone who proclaimed them for two thousand years. This book tells us how it happened.
