In the exhortation, the Holy Father mentioned, among other things, the dismissal rite of Mass and the need for a Compendium on the Eucharist:
Finally, I would like to comment briefly on the observations of the Synod Fathers regarding the dismissal at the end of the Eucharistic celebration. After the blessing, the deacon or the priest dismisses the people with the words: Ite, missa est. These words help us to grasp the relationship between the Mass just celebrated and the mission of Christians in the world. In antiquity, missa simply meant "dismissal." However in Christian usage it gradually took on a deeper meaning. The word "dismissal" has come to imply a "mission." These few words succinctly express the missionary nature of the Church. The People of God might be helped to understand more clearly this essential dimension of the Church's life, taking the dismissal as a starting-point. In this context, it might also be helpful to provide new texts, duly approved, for the prayer over the people and the final blessing, in order to make this connection clear. (n. 51, referring to Proposition n. 24)Both of these considerations are becoming a reality. There has been a recent revision to the third edition of the Roman Missal (from 2002) which includes these new texts. We won't hear these in English for a few years still.
At the conclusion of these reflections, in which I have taken up a number of themes raised at the Synod, I also wish to accept the proposal which the Synod Fathers advanced as a means of helping the Christian people to believe, celebrate and live ever more fully the mystery of the Eucharist. The competent offices of the Roman Curia will publish a Compendium which will assemble texts from the Catechism of the Catholic Church, prayers, explanations of the Eucharistic Prayers of the Roman Missal and other useful aids for a correct understanding, celebration and adoration of the Sacrament of the Altar. It is my hope that this book will help make the memorial of the Passover of the Lord increasingly the source and summit of the Church's life and mission. This will encourage each member of the faithful to make his or her life a true act of spiritual worship. (n. 93, referring to Proposition 17)
