Silence Speaks presents the stories of four internationally recognized 20th-century Catholic theologians and their conflicts with Church authority over their ideas and writings. Each of these men became subject to disciplinary actions that included a prohibition from teaching and writing for various periods of time. Each of them endured critical opposition for their theological insights on ecumenism, war and peace, evolution, the role of laypeople in the Church, and freedom of religion. Despite being silenced and suffering internal spiritual crises, each man remained obedient to the Church and ultimately enjoyed at least partial vindication of his views. Readers will find here in one volume a wealth of information gleaned from many sources.
