One of the concerns brought up by those who are not in the NCW is that the NCW does not celebrate the Mass inside the church building. They believe that by holding the Eucharistic celebrations outside the church building, the NCW has become a parallel church. Nothing could not be further from the truth. Our Catholic brothers who do not walk in the Way do not understand that we are all united by one faith, one baptism, and in union with the Holy See as the Body of Christ. To put it in simple terms, a physical place does not unite Christians.
The following quotes were taken from a paper written by Krzysztof Broszkowski entitled The Unity of the Parish and the Celebration of the Eucharist in Small Parish Communities in the Light of Recent Documents of the Magisterium of the Church. It is a 20 page document, which can be found here. Below are excerpts from his article, which I enumerated due to the fact that there are some people who believe that we are celebrating the Eucharist separately from the main parish. His article shows that the Neocatechumenal Way is not celebrating separately from the parish as a parallel church but whose celebration is one with the parish. You can read the entire paper in the weblink, but the bold is mine.
1. Eucharistic celebrations by small communities in a parish, often held outside the main church building, raise concerns, whether the unity of the parish is not disturbed. The reasons for those concerns are more of theological than pastoral nature and mostly relate to the communities of the Neocatechumenal Way. In order to find out if the concerns are justified in the light of the theological criteria, we will analyze selected Church documents of the 20th and the 21st century.
2. The document Communionis notio stresses that, since unity is a gift of God bestowed on people in sacraments, every Eucharist, even if it takes place in a small community, is a Eucharist of the catholic Church: Paragraph 10 “Moreover, one’s belonging to a particular Church never conflicts with the reality that in the Church no-one is a stranger: each member of the faithful, especially in the celebration of the Eucharist, is in his or her Church, in the Church of Christ, regardless of whether or not he or she belongs, according to canon law, to the diocese, parish or other particular community where the celebration takes place.7 In this sense, without impinging on the necessary regulations regarding juridical dependence, whoever belongs to one particular Church belongs to all the Churches; since belonging to the Communion, like belonging to the Church, is never simply particular, but by its very nature is always universal.”8
3. In the light of these words no Eucharist taking place in a small parish community is separated from other parishioners, since it is the celebration of the Paschal Mystery, the source of the communion. The Encyclical Letter Ecclesia de Eucharistia, written by John Paul II 10 years later, specifies in more detail how the paschal unity of the parish should be understood.
4. Other detailed instructions of the Congregation point to the growing acceptance towards celebrations in smaller groupings. This fact proves that, in theological sense, these celebrations are not contradictory to church unity, but serve as important pastoral tools.
5. In the Paragraph 52 of the Ecclesia de Eucharistia the Pope indicates that the communion, the unity of the whole community with the universal Church is guaranteed by the priest celebrating the Eucharist. Presiding at the Eucharist, the priest is responsible for doing it in persona Christi and must “provide a witness to and a service of communion not only for the community directly taking part in the celebration, but also for the universal Church, which is a part of every Eucharist.” John Paul II reminds about this truth in order to warn against making the celebration of the Eucharist a private event, and especially against introducing unauthorised changes. However, the rule itself can also serve as proof that through the celebration of the Eucharist separately, the community does not become a parallel church.
6. The charism of Neocatechumenate in the context of parish life was highly spoken about by a Spanish Cardinal, who is the current Prefect of the Congregation for Divine Worship and the Discipline of the Sacraments, Antonio Cañizares Llovera. The cardinal wrote about it in a short article for the Spanish weekly “La Razón:” “The Word of God, the Eucharist, baptism, received or to be received, and the Christian community, are the core of the itinerary of the growth of faith, which is accompanied by not strictly liturgical celebrations on its every stage. The Sunday Eucharist, usually anticipated on a Saturday night in neocatechumenal communities, is «the soul and strength» of the whole Way. The celebration of the Eucharist, performed within the proper itinerary of these communities, celebrated with the highest dignity, with the sense of «mystery and sacrum», in the spirit of the Church and liturgy. The Word of God and the Eucharist indicate God’s priority and form the basis that gives life, strength, capacity and enthusiasm to communities to enable them to give testimony of their faith.”14
7. According to Cañizares the relation between the liturgy and catechesis in the Neocatechumenal Way may serves as a model.15
In his encyclical letter Ecclesia de Eucharistia, St. John Paul II stated:
I remember the parish church of Niegowić, where I had my first pastoral assignment, the collegiate church of Saint Florian in Krakow, Wawel Cathedral, Saint Peter's Basilica and so many basilicas and churches in Rome and throughout the world. I have been able to celebrate Holy Mass in chapels built along mountain paths, on lakeshores and seacoasts; I have celebrated it on altars built in stadiums and in city squares... This varied scenario of celebrations of the Eucharist has given me a powerful experience of its universal and, so to speak, cosmic character. Yes, cosmic! Because even when it is celebrated on the humble altar of a country church, the Eucharist is always in some way celebrated on the altar of the world. It unites heaven and earth.
