There are “old things and new things” that belong to the treasury of the Church of all time, and must be considered as such. The wise man is able to find both of these in his treasury, without appealing to other criteria apart from those of the Gospel and the Church. Not all that is new is true, nor is all that is old. The truth spans old and new, and it is for this that we must strive, without prejudice. The Church lives according to the law of continuity in virtue of which it recognizes development rooted in tradition. What is most important is that everything work together so that the liturgical celebration truly is the celebration of the sacred mystery, of the crucified and risen Lord who becomes present in his Church, reenacting the mystery of salvation and calling us, in the logic of an authentic and active participation, to share to the full in his own life, which is a life given in love to the Father and to his brothers, a life of holiness.»
