“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 being… 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.”
