The day of the Church
35. Therefore, the
dies Domini is also the
dies Ecclesiae. This is why on the pastoral level the community aspect of the Sunday celebration should be particularly stressed. As I have noted elsewhere, among the many activities of a parish, "none is as vital or as community-forming as the Sunday celebration of the Lord's Day and his Eucharist".(46) Mindful of this, the Second Vatican Council recalled that efforts must be made to ensure that there is "within the parish, a lively sense of community, in the first place through the community celebration of Sunday Mass".(47) Subsequent liturgical directives made the same point, asking that on Sundays and holy days the Eucharistic celebrations held normally in other churches and chapels be coordinated with the celebration in the parish church, in order "to foster the sense of the Church community, which is nourished and expressed in a particular way by the community celebration on Sunday, whether around the Bishop, especially in the Cathedral, or in the parish assembly, in which the pastor represents the Bishop".(48)
36. The Sunday assembly is the privileged place of unity: it is the setting for the celebration of the
sacramentum unitatis which profoundly marks the Church as a people gathered "by" and "in" the unity of the Father, of the Son and of the Holy Spirit.(49) For Christian families, the Sunday assembly is one of the most outstanding expressions of their identity and their "ministry" as "domestic churches",(50) when parents share with their children at the one Table of the word and of the Bread of Life. We do well to recall in this regard that it is first of all the parents who must teach their children to participate in Sunday Mass; they are assisted in this by catechists, who are to see to it that initiation into the Mass is made a part of the formation imparted to the children entrusted to their care, explaining the important reasons behind the obligatory nature of the precept. When circumstances suggest it, the celebration of Masses for Children, in keeping with the provisions of the liturgical norms,(51) can also help in this regard.
At Sunday Masses in parishes, insofar as parishes are "Eucharistic communities",(52) it is normal to find different groups, movements, associations and even the smaller religious communities present in the parish. This allows everyone to experience in common what they share most deeply, beyond the particular spiritual paths which, by discernment of Church authority,(53) legitimately distinguish them. This is why on Sunday, the day of gathering, small group Masses are not to be encouraged: it is not only a question of ensuring that parish assemblies are not without the necessary ministry of priests, but also of ensuring that the life and unity of the Church community are fully safeguarded and promoted.(54) Authorization of possible and clearly restricted exceptions to this general guideline will depend upon the wise discernment of the Pastors of the particular Churches, in view of special needs in the area of formation and pastoral care, and keeping in mind the good of individuals or groups — especially the benefits which such exceptions may bring to the entire Christian community.
