We shall continue in the future to take special care to promote and follow the renewal of the Church according to the teaching of the Second Vatican Council, in the spirit of an ever living Tradition. In fact, to the substance of Tradition properly understood belongs also a correct re-reading of the "signs of the times, which require us to draw from the rich treasure of Revelation "things both new and old."(71) Acting in this spirit, in accordance with this counsel of the Gospel, the Second Vatican Council carried out a providential effort to renew the face of the Church in the sacred liturgy, most often having recourse to what is "ancient," what comes from the heritage of the Fathers and is the expression of the faith and doctrine of a Church which has remained united for so many centuries.
In order to be able to continue in the future to put into practice the directives of the Council in the field of liturgy, and in particular in the field of eucharistic worship, close collaboration is necessary between the competent department of the Holy See and each episcopal conference, a collaboration which must be at the same time vigilant and creative. We must keep our sights fixed on the greatness of the most holy Mystery and at the same time on spiritual movements and social changes, which are so significant for our times, since they not only sometimes create difficulties but also prepare us for a new way of participating in that great Mystery of Faith.
Above all I wish to emphasize that the problems of the liturgy, and in particular of the Eucharistic Liturgy, must not be an occasion of dividing Catholics and for threatening the unity of the Church. This is demanded by an elementary understanding of that sacrament which Christ has left us as the source of spiritual unity. And how could the Eucharist, which in the Church is the sacramentum pietatis, signum unitatis, vinculum caritatis,(72) form between us at this time a point or division and a source of distortion of thought and of behavior, instead of being the focal point and constitutive center, which it truly is in its essence, of the unity of the Church herself?
We are all equally indebted to our Redeemer. We should all listen together to that spirit of truth and of love whom He has promised to the Church and who is operative in her. In the name of this truth and of this love, in the name of the crucified Christ and of His Mother, I ask you, and beg you: Let us abandon all opposition and division, and let us all unite in this great mission of salvation which is the price and at the same time the fruit of our redemption. The Apostolic See will continue to do all that is possible to provide the means of ensuring that unity of which we speak. Let everyone avoid anything in his own way of acting which could "grieve the Holy Spirit."(73)
In order that this unity and the constant and systematic collaboration which leads to it may be perseveringly continued, I beg on my knees that, through the intercession of Mary, holy spouse of the Holy Spirit and Mother of the Church, we may all receive the light of the Holy Spirit. And blessing everyone, with all my heart I once more address myself to you, my venerable and dear brothers in the episcopate, with a fraternal greeting and with full trust. In this collegial unity in which we share, let us do all we can to ensure that the Eucharist may become an ever greater source of life and light for the consciences of all our brothers and sisters of all the communities in the universal unity of Christ's Church on earth.
In a spirit of fraternal charity, to you and to all our confreres in the priesthood I cordially impart the apostolic blessing.
From the Vatican, February 24, First Sunday of Lent, in the year 1980, the second of the Pontificate.
