St. Peter Celestine, Pope and Confessor

In the Catechism, we learn that visible churches are more than gathering places: they signify the Church living in that place, the dwelling of God with people reconciled and united in Christ. They are holy places where the community gathers for worship, hears God’s word, sings his praise, prays, and offers the sacrifice of Christ sacramentally present; they are also places of recollection and personal prayer. The altar recalls the Cross of Christ, and under sacramental signs the sacrifice of the Cross is made present as the People of God are invited to the Lord’s table. In the liturgy, the whole assembly participates according to each person’s role, joined to Christ our high priest and to the heavenly liturgy. Its signs and symbols, drawn from creation, human life, and salvation history, become bearers of Christ’s saving and sanctifying action. Sunday, the Lord’s Day and day of the Christian family, is the principal day for the Eucharist, joy, and rest. As the Church keeps the saints’ memorials, she is united with the liturgy of heaven, while Christians themselves become temples of the Holy Spirit.

The Catechism teaches that the Church celebrates the one Paschal mystery of Christ in every place, from the first community in Jerusalem until Christ’s return. Although this mystery is one, its liturgical celebration takes diverse forms. These traditions developed as the Church carried out her mission among different peoples and cultures, expressing the same faith through distinctive symbols, forms of communion, theological understanding, and ways of holiness. In the communion of the same faith and sacraments, the Churches can enrich one another and grow in fidelity to Tradition and the Church’s common mission. The Church recognizes the Latin, Byzantine, Alexandrian or Coptic, Syriac, Armenian, Maronite, and Chaldean rites, holding all lawfully recognized rites to be of equal right and dignity and seeking to preserve and foster them.

The liturgy proclaims, celebrates, and lives the mystery of Christ within many cultures, not abolishing them but redeeming and fulfilling them in Christ. It includes an unchanging part instituted by God and entrusted to the Church, as well as elements the Church may adapt to cultures when appropriate. Different recognized rites express and communicate the same mystery of Christ and show the catholicity of the Church. For family reflection, cultural expressions in worship are a gift when they remain faithful to the common faith, the sacramental signs received from Christ, and communion with the Church. The liturgy both finds expression in culture and helps shape it, while calling for conversion wherever customs are incompatible with the Catholic faith.
