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
For this reason the Church, especially during Advent and Lent and above all at the Easter Vigil, re-reads and re-lives the great events of salvation history in the "today" of her liturgy. But this also demands that catechesis help the faithful to open themselves to this spiritual understanding of the economy of salvation as the Church's liturgy reveals it and enables us to live it.
