To commemorate the fiftieth anniversary of the Second Vatican Council, three of the most important authors in the field of Spanish religious and theological thinking offer their reflections on the subject of faith. Each of them is a child of a Council member whose memory we are celebrating. The authors, each with their individual and distinct style, expose aspects concerning the Christian faith that can help readers to personalise it and make it ever more deeply their own. This book will help those who read it - whatever their personal or ecclesiastical status - feel lovingly looked upon by the Lord and be able to sincerely say those words of St. Paul: "I know whom I have believed."
