At the time of his resignation, Benedict had completed a draft of a fourth encyclical entitled "Lumen fidei" ("The Light of Faith"), intended to accompany his first two encyclicals to complete a trilogy on the three theological virtues of faith, hope, and love. Benedict's successor, Francis, completed and published "Lumen Fidei" in June 2013, four months after Benedict's retirement and Francis' succession. Although the encyclical is officially the work of Francis, paragraph 7 of the encyclical explicitly expresses Francis' debt to Benedict: "These considerations on faith — in continuity with all that the Church's magisterium has pronounced on this theological virtue — are meant to supplement what Benedict XVI had written in his encyclical letters on charity and hope. He himself had almost completed a first draft of an encyclical on faith. For this I am deeply grateful to him, and as his brother in Christ I have taken up his fine work and added a few contributions of my own."
