It is the whole community, the body of Christ, united with its head, which celebrates each of the sacraments. Thus, sacramental celebrations are always community celebrations and never private functions. To make visible the communal aspect of the sacraments, the church's preference is that they be celebrated within a significant gathering of the local community whenever possible. For the sacraments of initiation (i.e. Baptism, Confirmation, and Eucharist), this significant gathering of the local community takes place most clearly at the Sunday Mass.
