Christian Mystery›SECTION ONE THE SACRAMENTAL ECONOMY›CHAPTER TWO THE SACRAMENTAL CELEBRATION OF THE PASCHAL MYSTERY›IV. Where is the Liturgy Celebrated?
The gathering of the People of God begins with Baptism; a church must have a place for the celebration of Baptism (baptistry) and for fostering remembrance of the baptismal promises (holy water font). The renewal of the baptismal life requires penance. A church, then, must lend itself to the expression of repentance and the reception of forgiveness, which requires an appropriate place to receive penitents. A church must also be a space that invites us to the recollection and silent prayer that extend and internalize the great prayer of the Eucharist.
