"The Eucharist is a great mystery! And it is one which above all must be well celebrated. Holy Mass needs to be set at the centre of the Christian life and celebrated in a dignified manner by every community, in accordance with established norms, with the participation of the assembly, with the presence of ministers who carry out their assigned tasks, and with a serious concern that singing and liturgical music be suitably 'sacred.' One specific project of this Year of the Eucharist might be for each parish community to study the General Instruction of the Roman Missal. The best way to enter into the mystery of salvation made present in the sacred 'signs' remains that of following faithfully the unfolding of the liturgical year. Pastors should be committed to that 'mystagogical' catechesis so dear to the Fathers of the Church, by which the faithful are helped to understand the meaning of the liturgy's words and actions, to pass from its signs to the mystery which they contain, and to enter into that mystery in every aspect of their lives."
John Paul II, Apostolic Letter Mane Nobiscum Domine, 17
