Pope Francis has published his first encyclical Lumen Fidei, the Light of Faith, for the Year of Faith, completing Pope Emeritus Benedicts series of encyclicals on the Theological Virtues, Love, and Hope. Pope Francis writes the following about the Year of Faith:
’5. Christ, on the eve of his passion, assured Peter: “I have prayed for you that your faith may not fail” (Lk 22:32). He then told him to strengthen his brothers and sisters in that same faith. Conscious of the duty entrusted to the Successor of Peter, Benedict XVI proclaimed the present Year of Faith, a time of grace which is helping us to sense the great joy of believing and to renew our wonder at the vast horizons which faith opens up, so as then to profess that faith in its unity and integrity, faithful to the memory of the Lord and sustained by his presence and by the working of the Holy Spirit. The conviction born of a faith which brings grandeur and fulfilment to life, a faith centred on Christ and on the power of his grace, inspired the mission of the first Christians. In the acts of the martyrs, we read the following dialogue between the Roman prefect Rusticus and a Christian named Hierax: “‘Where are your parents?’, the judge asked the martyr. He replied: ‘Our true father is Christ, and our mother is faith in him’”.
 For those early Christians, faith, as an encounter with the living God revealed in Christ, was indeed a “mother”, for it had brought them to the light and given birth within them to divine life, a new experience and a luminous vision of existence for which they were prepared to bear public witness to the end.
6. The Year of Faith was inaugurated on the fiftieth anniversary of the opening of the Second Vatican Council. This is itself a clear indication that Vatican II was a Council on faith, inasmuch as it asked us to restore the primacy of God in Christ to the centre of our lives, both as a Church and as individuals. The Church never takes faith for granted, but knows that this gift of God needs to be nourished and reinforced so that it can continue to guide her pilgrim way. The Second Vatican Council enabled the light of faith to illumine our human experience from within, accompanying the men and women of our time on their journey. It clearly showed how faith enriches life in all its dimensions.
7. 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. The Successor of Peter, yesterday, today and tomorrow, is always called to strengthen his brothers and sisters in the priceless treasure of that faith which God has given as a light for humanity’s path.
In God’s gift of faith, a supernatural infused virtue, we realize that a great love has been offered us, a good word has been spoken to us, and that when we welcome that word, Jesus Christ the Word made flesh, the Holy Spirit transforms us, lights up our way to the future and enables us joyfully to advance along that way on wings of hope. Thus wonderfully interwoven, faith, hope and charity are the driving force of the Christian life as it advances towards full communion with God. But what is it like, this road which faith opens up before us? What is the origin of this powerful light which brightens the journey of a successful and fruitful life?
