This work provides an account of many Jesuits, from the time of St. Ignatius to the 1990s, who have been incarcerated around the world for their faith. It is divided into chapters that deal with specific themes related to their imprisonment. The principal themes are: prayer as a key element in survival, arrest and trial procedures, the experience of suffering, Mass, the daily drudge of prison life, forced labour, ministry to other prisoners, guards, prisoners who became Jesuits while imprisoned, community in prison, and voluntary incarceration. This is one of the first books to examine the experience of incarcerated Jesuits around the world and down through the centuries from the standpoint of these various themes. Much of the material is by the Jesuits themselves, in letters, autobiographical fragments and other sources - including obscure publications long out of print. The result is a gathering together of these pieces and fragments into a coordinated whole, with commentary on their significance in the context of the political and cultural situations of their time - situations that were generally the immediate cause of the Jesuits imprisonment, whether in Elizabethan England or in Communist China and Russia. A chart of imprisoned Jesuits by country of incarceration at the beginning, and a glossary of names at the back (as well as an index), aims to help the reader to keep track of the names of the many Jesuits who figure in the book.
