Christian Mystery›SECTION ONE THE SACRAMENTAL ECONOMY›CHAPTER TWO THE SACRAMENTAL CELEBRATION OF THE PASCHAL MYSTERY›III. When is the Liturgy Celebrated?
Beginning with the Easter Triduum as its source of light, the new age of the Resurrection fills the whole liturgical year with its brilliance. Gradually, on either side of this source, the year is transfigured by the liturgy. It really is a "year of the Lord's favor." The economy of salvation is at work within the framework of time, but since its fulfillment in the Passover of Jesus and the outpouring of the Holy Spirit, the culmination of history is anticipated "as a foretaste," and the kingdom of God enters into our time.
