of the Year of Faith
The “door of faith” (Acts 14:27) is always open for us, ushering us into the life of communion with God and offering entry into his Church. It is possible to cross that threshold when the word of God is proclaimed and the heart allows itself to be shaped by transforming grace. To enter through that door is to set out on a journey that lasts a lifetime. It begins with baptism (cf. Rom 6:4), through which we can address God as Father, and it ends with the passage through death to eternal life, fruit of the resurrection of the Lord Jesus, whose will it was, by the gift of the Holy Spirit, to draw those who believe in him into his own glory (cf. Jn 17:22). To profess faith in the Trinity – Father, Son and Holy Spirit – is to believe in one God who is Love (cf. 1 Jn 4:8): the Father, who in the fullness of time sent his Son for our salvation; Jesus Christ, who in the mystery of his death and resurrection redeemed the world; the Holy Spirit, who leads the Church across the centuries as we await the Lord’s glorious return.
Ever since the start of my ministry as Successor of Peter, I have spoken of the need to rediscover the journey of faith so as to shed ever clearer light on the joy and renewed enthusiasm of the encounter with Christ. During the homily at the Mass marking the inauguration of my pontificate I said: “The Church as a whole and all her Pastors, like Christ, must set out to lead people out of the desert, towards the place of life, towards friendship with the Son of God, towards the One who gives us life, and life in abundance.”1
It often happens that Christians are more concerned for the social, cultural and political consequences of their commitment, continuing to think of the faith as a self-evident presupposition for life in society. In reality, not only can this presupposition no longer be taken for granted, but it is often openly denied.2 Whereas in the past it was possible to recognize a unitary cultural matrix, broadly accepted in its appeal to the content of the faith and the values inspired by it, today this no longer seems to be the case in large swathes of society, because of a profound crisis of faith that has affected many people.
We cannot accept that salt should become tasteless or the light be kept hidden (cf. Mt 5:13-16). The people of today can still experience the need to go to the well, like the Samaritan woman, in order to hear Jesus, who invites us to believe in him and to draw upon the source of living water welling up within him (cf. Jn 4:14). We must rediscover a taste for feeding ourselves on the word of God, faithfully handed down by the Church, and on the bread of life, offered as sustenance for his disciples (cf. Jn 6:51). Indeed, the teaching of Jesus still resounds in our day with the same power: “Do not labour for the food which perishes, but for the food which endures to eternal life” (Jn 6:27). The question posed by his listeners is the same that we ask today: “What must we do, to be doing the works of God?” (Jn 6:28). We know Jesus’ reply: “This is the work of God, that you believe in him whom he has sent” (Jn 6:29). Belief in Jesus Christ, then, is the way to arrive definitively at salvation.
In the light of all this, I have decided to announce a Year of Faith.
On this happy occasion, I wish to invite my brother bishops from all over the world to join the Successor of Peter, during this time of spiritual grace that the Lord offers us, in recalling the precious gift of faith. We want to celebrate this Year in a worthy and fruitful manner.
Not without reason, Christians in the early centuries were required to learn the creed from memory. It served them as a daily prayer not to forget the commitment they had undertaken in baptism. With words rich in meaning, Saint Augustine speaks of this in a homily on the redditio symboli, the handing over of the creed: “the symbol of the holy mystery that you have all received together and that today you have recited one by one, are the words on which the faith of Mother Church is firmly built above the stable foundation that is Christ the Lord. You have received it and recited it, but in your minds and hearts you must keep it ever present, you must repeat it in your beds, recall it in the public squares and not forget it during meals: even when your body is asleep, you must watch over it with your hearts.”16
At this point I would like to sketch a path intended to help us understand more profoundly not only the content of the faith, but also the act by which we choose to entrust ourselves fully to God, in complete freedom. In fact, there exists a profound unity between the act by which we believe and the content to which we give our assent. Saint Paul helps us to enter into this reality when he writes: “Man believes with his heart and so is justified, and he confesses with his lips and so is saved” (Rom 10:10). The heart indicates that the first act by which one comes to faith is God’s gift and the action of grace which acts and transforms the person deep within.
On the other hand, we must not forget that in our cultural context, very many people, while not claiming to have the gift of faith, are nevertheless sincerely searching for the ultimate meaning and definitive truth of their lives and of the world. This search is an authentic “preamble” to the faith, because it guides people onto the path that leads to the mystery of God. Human reason, in fact, bears within itself a demand for “what is perennially valid and lasting”.19 This demand constitutes a permanent summons, indelibly written into the human heart, to set out to find the One whom we would not be seeking had he not already set out to meet us.20 To this encounter, faith invites us and it opens us in fullness.
13. One thing that will be of decisive importance in this Year is retracing the history of our faith, marked as it is by the unfathomable mystery of the interweaving of holiness and sin. While the former highlights the great contribution that men and women have made to the growth and development of the community through the witness of their lives, the latter must provoke in each person a sincere and continuing work of conversion in order to experience the mercy of the Father which is held out to everyone.
During this time we will need to keep our gaze fixed upon Jesus Christ, the “pioneer and perfecter of our faith” (Heb 12:2): in him, all the anguish and all the longing of the human heart finds fulfilment. The joy of love, the answer to the drama of suffering and pain, the power of forgiveness in the face of an offence received and the victory of life over the emptiness of death: all this finds fulfilment in the mystery of his Incarnation, in his becoming man, in his sharing our human weakness so as to transform it by the power of his resurrection. In him who died and rose again for our salvation, the examples of faith that have marked these two thousand years of our salvation history are brought into the fullness of light.
By faith, Mary accepted the Angel’s word and believed the message that she was to become the Mother of God in the obedience of her devotion (cf. Lk 1:38). Visiting Elizabeth, she raised her hymn of praise to the Most High for the marvels he worked in those who trust him (cf. Lk 1:46-55). With joy and trepidation she gave birth to her only son, keeping her virginity intact (cf. Lk 2:6-7). Trusting in Joseph, her husband, she took Jesus to Egypt to save him from Herod’s persecution (cf. Mt 2:13-15). With the same faith, she followed the Lord in his preaching and remained with him all the way to Golgotha (cf. Jn 19:25-27). By faith, Mary tasted the fruits of Jesus’ resurrection, and treasuring every memory in her heart (cf. Lk 2:19, 51), she passed them on to the Twelve assembled with her in the Upper Room to receive the Holy Spirit (cf. Acts 1:14; 2:1-4).
By faith, the Apostles left everything to follow their Master (cf. Mk 10:28). They believed the words with which he proclaimed the Kingdom of God present and fulfilled in his person (cf. Lk 11:20). They lived in communion of life with Jesus who instructed them with his teaching, leaving them a new rule of life, by which they would be recognized as his disciples after his death (cf. Jn 13:34-35). By faith, they went out to the whole world, following the command to bring the Gospel to all creation (cf. Mk16:15) and they fearlessly proclaimed to all the joy of the resurrection, of which they were faithful witnesses.
By faith, the disciples formed the first community, gathered around the teaching of the Apostles, in prayer, in celebration of the Eucharist, holding their possessions in common so as to meet the needs of the brethren (cf. Acts 2:42-47).
By faith, the martyrs gave their lives, bearing witness to the truth of the Gospel that had transformed them and made them capable of attaining to the greatest gift of love: the forgiveness of their persecutors.
By faith, men and women have consecrated their lives to Christ, leaving all things behind so as to live obedience, poverty and chastity with Gospel simplicity, concrete signs of waiting for the Lord who comes without delay. By faith, countless Christians have promoted action for justice so as to put into practice the word of the Lord, who came to proclaim deliverance from oppression and a year of favour for all (cf. Lk 4:18-19).
By faith, across the centuries, men and women of all ages, whose names are written in the Book of Life (cf. Rev 7:9, 13:8), have confessed the beauty of following the Lord Jesus wherever they were called to bear witness to the fact that they were Christian: in the family, in the workplace, in public life, in the exercise of the charisms and ministries to which they were called.
By faith, we too live: by the living recognition of the Lord Jesus, present in our lives and in our history.
Having reached the end of his life, Saint Paul asks his disciple Timothy to “aim at faith” (2 Tim 2:22) with the same constancy as when he was a boy (cf. 2 Tim 3:15). We hear this invitation directed to each of us, that none of us grow lazy in the faith. It is the lifelong companion that makes it possible to perceive, ever anew, the marvels that God works for us. Intent on gathering the signs of the times in the present of history, faith commits every one of us to become a living sign of the presence of the Risen Lord in the world. What the world is in particular need of today is the credible witness of people enlightened in mind and heart by the word of the Lord, and capable of opening the hearts and minds of many to the desire for God and for true life, life without end.
“That the word of the Lord may speed on and triumph” (2 Th3:1): may this Year of Faith make our relationship with Christ the Lord increasingly firm, since only in him is there the certitude for looking to the future and the guarantee of an authentic and lasting love. The words of Saint Peter shed one final ray of light on faith: “In this you rejoice, though now for a little while you may have to suffer various trials, so that the genuineness of your faith, more precious than gold which though perishable is tested by fire, may redound to praise and glory and honour at the revelation of Jesus Christ. Without having seen him you love him; though you do not now see him you believe in him and rejoice with unutterable and exalted joy. As the outcome of your faith you obtain the salvation of your souls” (1 Pet1:6-9).
The life of Christians knows the experience of joy as well as the experience of suffering. How many of the saints have lived in solitude! How many believers, even in our own day, are tested by God’s silence when they would rather hear his consoling voice! The trials of life, while helping us to understand the mystery of the Cross and to participate in the sufferings of Christ (cf. Col 1:24), are a prelude to the joy and hope to which faith leads: “when I am weak, then I am strong” (2 Cor 12:10). We believe with firm certitude that the Lord Jesus has conquered evil and death. With this sure confidence we entrust ourselves to him: he, present in our midst, overcomes the power of the evil one (cf. Lk11:20); and the Church, the visible community of his mercy, abides in him as a sign of definitive reconciliation with the Father.
Let us entrust this time of grace to the Mother of God, proclaimed “blessed because she believed” (Lk1:45).
