This is an exclusive interview of Cardinal Muller, the head of the Vatican Congregation for the Doctrine of the Faith, and one of the most outstanding Catholic figures in theology today. As the Prefect of the CDF, he has a privileged perspective on the worldwide state of the Church on doctrinal, moral and theological matters, and the questions Catholics and others have today on those matters. This interview takes hope as its basic subject: it is a “report on hope”. It is an in-depth discussion of hope in relation to faith and love, and in relation to Jesus Christ, the Church, the family, and contemporary society. Paper.
