Such is the mystery of Christ, revealed and fulfilled in history according to the wisely ordered plan that St. Paul calls the "plan of the mystery" 2 and the patristic tradition will call the "economy of the Word incarnate" or the "economy of salvation."
Catechism number 1075
Liturgical catechesis aims to initiate people into the mystery of Christ (It is
"mystagogy." ) by proceeding from the visible to the invisible, from
the sign to the thing signified, from the "sacraments" to the
"mysteries."
Such catechesis is to be presented by local and regional catechisms.
This Catechism, which aims to serve the whole Church in all the diversity of
her rites and cultures,15 will present what is fundamental and common
to the whole Church in the liturgy as mystery and as celebration, and then the
seven sacraments and the sacramentals.
