CIC 1076 The Church was made manifest to the world on the day of Pentecost by the outpouring of the Holy Spirit.1 The gift of the Spirit ushers in a new era in the “dispensation of the mystery” the age of the Church, during which Christ manifests, makes present, and communicates his work of salvation through the liturgy of his Church, “until he comes.”2 In this age of the Church Christ now lives and acts in and with his Church, in a new way appropriate to this new age. He acts through the sacraments in what the common Tradition of the East and the West calls “the sacramental economy”; this is the communication (or “dispensation”) of the fruits of Christ’s Paschal mystery in the celebration of the Church’s “sacramental” liturgy.
It is therefore important first to explain this “sacramental dispensation” (chapter one). The nature and essential features of liturgical celebration will then appear more clearly (chapter two).
