Yes, it is a proven fact. And I will prove it.
Already posted by Spirithound:
Can. 381 §1. A diocesan bishop in the diocese entrusted to him has all ordinary, proper, and immediate power which is required for the exercise of his pastoral function except for cases which the law or a decree of the Supreme Pontiff reserves to the supreme authority or to another ecclesiastical authority.
Sacrosanctum Concilium:
- Regulation of the Sacred Liturgy depends solely on the authority of the Church, that is, on the Apostolic See and, as laws may determine, on the bishop.
- In virtue of power conceded by the law, the regulation of the Liturgy within certain defined limits belongs also to various kinds of competent territorial bodies of bishops legitimately established.
- Therefore no other person, even if he be a priest, may add, remove, or change anything in the Liturgy on his own authority. Note please that the word used in the original Latin is sacerdos, which means priest/bishop and not presbyter which means priest-not-bishop.
Redemptionis Sacramentum:
[14.] “The regulation of the Sacred Liturgy depends solely on the authority of the Church, which rests specifically with the Apostolic See and, according to the norms of law, with the Bishop”.
[17.] “The Congregation for Divine Worship and the Discipline of the Sacraments attends to those matters that pertain to the Apostolic See as regards the regulation and promotion of the Sacred Liturgy, and especially the Sacraments, with due regard for the competence of the Congregation for the Doctrine of the Faith. It fosters and enforces sacramental discipline, especially as regards their validity and their licit celebration”. Finally, it “carefully seeks to ensure that the liturgical regulations are observed with precision, and that abuses are prevented or eliminated whenever they are detected”. In this regard, according to the tradition of the universal Church, pre-eminent solicitude is accorded the celebration of Holy Mass, and also to the worship that is given to the Holy Eucharist even outside Mass.
[24.] It is the right of the Christian people themselves that their diocesan Bishop should take care to prevent the occurrence of abuses in ecclesiastical discipline, especially as regards the ministry of the word, the celebration of the sacraments and sacramentals, the worship of God and devotion to the Saints.
Notitiae April 1999 from the CDCWS
Query: Whether in dioceses where it is allowed to distribute Communion in the hands of the faithful, a priest or extraordinary ministers of Holy Communion may restrict communicants to receive Communion only in their hands, not on the tongue.
Response: Certainly it is clear from the very documents of the Holy See that in dioceses where the Eucharistic bread is put in the hands of the faithful, the right to receive the Eucharistic bread on the tongue still remains intact to the faithful. Therefore, those who restrict communicants to receive Holy Communion only on in the hands are acting against the norms, …
Now my question is this:
Would you care to prove your assertion that the bishop does have the authority to deny the faithful the right to receive Communion on the tongue???
