...6. The renewal of the Church is also achieved through the witness offered by the lives of believers: by their very existence in the world, Christians are called to radiate the word of truth that the Lord Jesus has left us. The Council itself, in the Dogmatic Constitution Lumen Gentium, said this: While “Christ, ‘holy, innocent and undefiled’ (Heb 7:26) knew nothing of sin (2 Cor 5:21), but came only to expiate the sins of the people (Heb 2:17)... the Church ... clasping sinners to its bosom, at once holy and always in need of purification, follows constantly the path of penance and renewal. The Church, ‘like a stranger in a foreign land, presses forward amid the persecutions of the world and the consolations of God’, announcing the cross and death of the Lord until he comes (1 Cor 11:26). But by the power of the risen Lord it is given strength to overcome, in patience and in love, its sorrow and its difficulties, both those that are from within and those that are from without, so that it may reveal in the world, faithfully, although with shadows, the mystery of its Lord until, in the end, it shall be manifested in full light.”

The Year of Faith, from this perspective, is a summons to an authentic and renewed conversion to the Lord, the one Saviour of the world. In the mystery of his death and resurrection, God has revealed in its fullness the Love that saves and calls us to conversion of life through the forgiveness of sins (Acts 5:31). For Saint Paul, this Love ushers us into a new life: “We were buried ... with him by baptism into death, so that as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life” (Rom 6:4). Through faith, this new life shapes the whole of human existence according to the radical new reality of the resurrection. To the extent that he freely cooperates, man’s thoughts and affections, mentality and conduct are slowly purified and transformed, on a journey that is never completely finished in this life. “Faith working through love” (Gal 5:6) becomes a new criterion of understanding and action that changes the whole of man’s life (Rom 12:2; Col 3:9-10; Eph 4:20-29; 2 Cor 5:17).

7. “Caritas Christi urget nos” (2 Cor 5:14): it is the love of Christ that fills our hearts and impels us to evangelize. Today as in the past, he sends us through the highways of the world to proclaim his Gospel to all the peoples of the earth (Mt 28:19). Through his love, Jesus Christ attracts to himself the people of every generation: in every age he convokes the Church, entrusting her with the proclamation of the Gospel by a mandate that is ever new. Today too, there is a need for stronger ecclesial commitment to new evangelization in order to rediscover the joy of believing and the enthusiasm for communicating the faith. In rediscovering his love day by day, the missionary commitment of believers attains force and vigour that can never fade away. Faith grows when it is lived as an experience of love received and when it is communicated as an experience of grace and joy. It makes us fruitful, because it expands our hearts in hope and enables us to bear life-giving witness: indeed, it opens the hearts and minds of those who listen to respond to the Lord’s invitation to adhere to his word and become his disciples. Believers, so Saint Augustine tells us, “strengthen themselves by believing”. The saintly Bishop of Hippo had good reason to express himself in this way. As we know, his life was a continual search for the beauty of the faith until such time as his heart would find rest in God. His extensive writings, in which he explains the importance of believing and the truth of the faith, continue even now to form a heritage of incomparable riches, and they still help many people in search of God to find the right path towards the “door of faith”.
