Part II,Chapter II,Article 2: Liturgical diversity and the unity of the Mystery..Liturgical traditions and the catholicity of the Church. 1201:The mystery of Christ is so unfathomably rich that it cannot be exhausted by its expression in any single liturgical tradition.

The history of the blossoming and development of these rites witnesses to a remarkable complementarity. When the Churches lived their respective liturgical traditions in the communion of the faith and the sacraments of the faith, they enriched one another and grew in fidelity to Tradition and to the common mission of the whole Church.

1202: The diverse liturgical traditions have arisen by very reason of the Church’s mission. Churches of the same geographical and cultural area came to celebrate the mystery of Christ through particular expressions characterized by culture: in the tradition of the “deposit of faith”, in liturgical symbolism, in the organization of fraternal communion, in the theological understanding of the mysteries, and in various forms of holiness....

1203:The liturgical traditions or rites presently in use, are the Latin (principally the Roman rite, but also the rise of certain local churches, such as the Ambrosian rite, or those of certain religious orders) and the Byzantine, Alexandrain or Coptic, Syriac Armenian, Maronite and Chaldean rites. In faithful obedience to tradition the Sacred Council declares that holy Mother Church holds all lawfully recognized rites to be of equal right and dignity, and that she wishes to preserve them in the future and to foster them in every way”.

1206:“Liturgical diversity can be a source of enrichment, but it can also provoke tensions, mutual misunderstandings and even schisms. In this matter it is clear that diversity must not damage unity. It must express only fidelity to the common faith, to the sacramental signs that the Church has received from Christ, and to hierarchical communion. Cultural adaptation also requires a conversion of heart and even, where necessary, a breaking with ancestral customs incompatible with the Catholic faith”.
