Liturgical catechesis in church documents
Constitution on the Sacred Liturgy: Sacrosanctum consilium (1963) 35: 3) "Instruction which is more explicitly liturgical should also be given in a variety of ways; if necessary, short directives to be spoken by the priest or proper minister should be provided within the rites themselves. But they should occur only at the more suitable moments, and be in prescribed or similar words."
Catechesi tradendae (1979) #23: "Catechesis is intrinsically linked with the whole of liturgical and sacramental activity, for it is in the sacraments, especially in the Eucharist, that Christ Jesus works in fullness for the transformation of human beings.
In the early Church, the catechumenate and preparation for the sacraments of Baptism and the Eucharist were the same thing. ... In any case, catechesis always has reference to the sacraments. On the one hand, the catechesis that prepares for the sacraments is an eminent kind, and every form of catechesis necessarily leads to the sacraments of faith. On the other hand, authentic practice of the sacraments is bound to have a catechetical aspect. In other words, sacramental life is impoverished and very soon turns into hollow ritualism if it is not based on serious knowledge of the meaning of the sacraments, and catechesis becomes intellectualized if it fails to come alive in the sacramental practice."
Code of Canon Law (1983) #777: "Attentive to the norms established by the diocesan bishop, a pastor is to take care in a special way:
1/ that suitable catechesis is imparted for the celebration of the sacraments;
2/ that through catechetical instruction imparted for an appropriate period of time children are prepared properly for the first reception of the sacraments of penance and the Most Holy Eucharist and for the sacrament of confirmation..."
Catechism of the Catholic Church (1997) #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."
General Directory for Catechesis (1997)
#30 "...'Catechesis is intrinsically bound to every liturgical and sacramental action.' Frequently however, the practice of catechetics testifies to a weak and fragmetary link with the liturgy: limited attention to liturgical symbols and rites, scant use of the liturgical fonts, catechetical courses with little or no connection with the liturgical year; the marginalization of liturgical celebrations in catechetical programs.."
#71 "Liturgical catechesis, prepares for the sacraments by promoting a deeper understanding and experience of the liturgy. This explains the contents of the prayers, the meaning of the signs and gestures, educates to active paricipation, contemplation and silence. It must be regarded as an 'eminent kind of catechesis'."
National Directory for Catechesis (2003) #110 "In the Church's ministry of evangelization, catechesis and Liturgy are intimately connected."
