Christian Mystery›SECTION ONE THE SACRAMENTAL ECONOMY›CHAPTER ONE THE PASCHAL MYSTERY IN THE AGE OF THE CHURCH›III. The Holy Spirit and the Church in the Liturgy
In the liturgy of the New Covenant every liturgical action, especially the celebration of the Eucharist and the sacraments, is an encounter between Christ and the Church. the liturgical assembly derives its unity from the "communion of the Holy Spirit" who gathers the children of God into the one Body of Christ. This assembly transcends racial, cultural, social - indeed, all human affinities.
