The day that Benedict XVI formally assumed as bishop of Rome, during the pronounced homily interspersed the phrase: "We suffer for the patience of God." This book explores this statement that assumes the enigma of evil, not evading but facing the role that God plays in this regard. The purpose is to unravel, in Joseph Ratzinger, the presence of a theology of God's patience and how it gives rise to the suffering of men. It is a question of explaining through this theological category what has been implicitly said through other theological categories related to the mystery of the divine permission. The work also offers a theological illumination of the pastoral ministry of Benedict XVI as successor of Peter. Indeed, over the years, the chosen phrase has been revealed as prophetic regarding a pontificate marked by adversities.
