[D]uring the [Second Vatican] Council there was an emotional tension as we faced the common task of making the truth and beauty of the faith shine out in our time, without sacrificing it to the demands of the present or leaving it tied to the past: the eternal presence of God resounds in the faith, transcending time, yet it can only be welcomed by us in our own unrepeatable today. Therefore I believe that the most important thing, especially on such a significant occasion as this, is to revive in the whole Church that positive tension, that yearning to announce Christ again to contemporary man. But, so that this interior thrust towards the new evangelization neither remain just an idea nor be lost in confusion, it needs to be built on a concrete and precise basis, and this basis is the documents of the Second Vatican Council, the place where it found expression. This is why I have often insisted on the need to return, as it were, to the “letter” of the Council – that is to its texts – also to draw from them its authentic spirit, and why I have repeated that the true legacy of Vatican II is to be found in them. Reference to the documents saves us from extremes of anachronistic nostalgia and running too far ahead, and allows what is new to be welcomed in a context of continuity. The Council did not formulate anything new in matters of faith, nor did it wish to replace what was ancient. Rather, it concerned itself with seeing that the same faith might continue to be lived in the present day, that it might remain a living faith in a world of change.

If we place ourselves in harmony with the authentic approach which Blessed John XXIIIwished to give to Vatican II, we will be able to realize it during this Year of Faith, following the same path of the Church as she continuously endeavours to deepen the deposit of faith entrusted to her by Christ. The Council Fathers wished to present the faith in a meaningful way; and if they opened themselves trustingly to dialogue with the modern world it is because they were certain of their faith, of the solid rock on which they stood. In the years following, however, many embraced uncritically the dominant mentality, placing in doubt the very foundations of the deposit of faith, which they sadly no longer felt able to accept as truths.

If today the Church proposes a new Year of Faith and a new evangelization, it is not to honour an anniversary, but because there is more need of it, even more than there was fifty years ago! And the reply to be given to this need is the one desired by the Popes, by the Council Fathers and contained in its documents. Even the initiative to create a Pontifical Council for the promotion of the new evangelization, which I thank for its special effort for the Year of Faith, is to be understood in this context. Recent decades have seen the advance of a spiritual “desertification”. In the Council’s time it was already possible from a few tragic pages of history to know what a life or a world without God looked like, but now we see it every day around us. This void has spread. But it is in starting from the experience of this desert, from this void, that we can again discover the joy of believing, its vital importance for us, men and women. In the desert we rediscover the value of what is essential for living; thus in today’s world there are innumerable signs, often expressed implicitly or negatively, of the thirst for God, for the ultimate meaning of life. And in the desert people of faith are needed who, with their own lives, point out the way to the Promised Land and keep hope alive. Living faith opens the heart to the grace of God which frees us from pessimism. Today, more than ever, evangelizing means witnessing to the new life, transformed by God, and thus showing the path.
