Christian Mystery›SECTION ONE THE SACRAMENTAL ECONOMY›CHAPTER TWO THE SACRAMENTAL CELEBRATION OF THE PASCHAL MYSTERY›II. How is the Liturgy Celebrated?
Signs of the covenant. the Chosen People received from God distinctive signs and symbols that marked its liturgical life. These are no longer solely celebrations of cosmic cycles and social gestures, but signs of the covenant, symbols of God's mighty deeds for his people. Among these liturgical signs from the Old Covenant are circumcision, anointing and consecration of kings and priests, laying on of hands, sacrifices, and above all the Passover. the Church sees in these signs a prefiguring of the sacraments of the New Covenant.
