-- Is 49:1-6
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 the 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. Through the liturgical life of a local church, Christ, the light and salvation of all peoples, is made manifest to the particular people and culture to which that Church is sent and in which she is rooted. The Church is catholic, capable of integrating into her unity, while purifying them, all the authentic riches of cultures.
