As quoted from Pope Benedict on the web site:
The Church throughout the world is preparing to celebrate the Year of Faith to mark the fiftieth anniversary of the start of the Second Vatican Council an event which launched the most extensive renewal of the Roman Rite ever known. Based upon a deepening appreciation of the sources of the liturgy, the Council promoted the full and active participation of the faithful in the Eucharistic sacrifice.
At our distance today from the Council Fathers’ expressed desires regarding liturgical renewal, and in the light of the universal Church’s experience in the intervening period, it is clear that a great deal has been achieved; but it is equally clear that there have been many misunderstandings and irregularities. The renewal of external forms, desired by the Council Fathers, was intended to make it easier to enter into the inner depth of the mystery.
Its true purpose was to lead people to a personal encounter with the Lord, present in the Eucharist, and thus with the living God, so that through this contact with Christ’s love, the love of his brothers and sisters for one another might also grow. Yet not infrequently, the revision of liturgical forms has remained at an external level, and "active participation" has been confused with external activity.
Hence much still remains to be done on the path of real liturgical renewal. In a changed world, increasingly fixated on material things, we must learn to recognize anew the mysterious presence of the Risen Lord, which alone can give breadth and depth to our life.
