We’ve been through this same argument hunderds of times in this forum, and neither side has changed their position.
I will change my position when confronted with evidence that a bishop may legally forbid a universal practice of the Church.
However, I’ve yet to see Mass(other than the TLM) said, ad orientum, but that doesn’t mean it hasn’t happen.
I haven’t
personally seen it either (outside of the EF), but Pope Benedict celebrated
ad orientem back in January.
The instruction itself recalls how the Diocesan Bishop is “the first steward of the mysteries of God in the particular Church entrusted to him, is the moderator, promoter and guardian of her whole liturgical life.” (RS, no. 19) and quotes from the Code of Canon Law, which directs that it pertains to the Diocesan Bishop (CIC, no. 838 §4) “within the limits of his competence, to set forth liturgical norms in his Diocese, by which all are bound.” (RS, no. 21, citing CIC, no. 838 §4)
In regard to the celebration of the Eucharist, the Diocesan Bishop is given a particular role in the publication of norms for the regulation of the liturgy in his particular diocese. The General Instruction of the Roman Missal [GIRM] assigns to the Diocesan Bishop the publication of norms on concelebration (GIRM, no. 202), service at the altar (GIRM, no. 107), Holy Communion under both kinds (GIRM, nos. 282-283), the construction and renovation of church Buildings (GIRM, no. 291 and 315), posture [GIRM no. 43.3, **liturgical music
(GIRM, nos. 48, 87), and the establishment of
days of prayer (GIRM, no. 373). (see “The Diocesan Bishop and the Missale Romanum, editio typica tertia, in The BCL Newsletter: July, 2002, page 82. Also available at
usccb.org/liturgy/innews/072002.shtml)).
Other rights of the Diocesan Bishop to regulate the liturgy are described by documents other than the GIRM, including the regulation of Masses on radio, television and via the internet, and his responsibility to establish a diocesan calendar. With the exception of these and other modifications of the law explicitly assigned to the Diocesan Bishop, no additional changes to liturgical law may be introduced to Diocesan liturgical practice without the specific prior of the Holy See.
So we are still left wondering if a Bishop can outlaw Latin,
ad orientem (which is posture!), or Communion on the tongue. That is, is such power within his competency? I posit that he cannot, that it is not.
When it comes to Latin…
- GIRM 12: “Since no Catholic would now deny the lawfulness and efficacy of a sacred rite celebrated in Latin…”
- GIRM 41: “Since faithful from different countries come together ever more frequently, it is fitting that they know how to sing together at least some parts of the Ordinary of the Mass in Latin…”
When it comes to Communion on the tongue:
- GIRM 160-161: “The consecrated host may be received either on the tongue or in the hand, at the discretion of each communicant. … The communicant replies, Amen, and receives the Sacrament either on the tongue or, where this is allowed and if the communicant so chooses, in the hand.”
- Response to Dubium on Communion in the Hand: “…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…”
- Redemptionis Sacramentum 92: “Although each of the faithful always has the right to receive Holy Communion on the tongue…”
On the topic of
ad orientem worship, which (as I mentioned) is posture, let us look again at the quote you gave: “posture (GIRM no. 43.3)”.
What does GIRM 43.3 govern? The posture of the faithful throughout the various parts of the Mass (i.e. when to sit, stand, and kneel). That doesn’t which direction a priest faces. What is interesting is that GIRM 42 (which mentions the posture of the priest) says that “attention should be paid to what is determined by this General Instruction
and the traditional practice of the Roman Rite and to what serves the common spiritual good of the People of God, rather than private inclination or arbitrary choice.” Since
ad orientem is a “traditional practice” and can “[serve] the common spiritual good” and is not forbidden by the GIRM (and in fact is implicit in the Missal and GIRM itself, see nn. 243-244), it is an option available to the priest.
Also, see the oft-referenced
“Letter on the position of the priest during the Eucharistic Liturgy”. It says, in part: “[GIRM 299] reaffirms that the position toward the assembly seems more convenient inasmuch as it makes communication easier (Cf. the editorial in Notitiae 29 [1993] 245-249),
without excluding, however, the other possibility.” Here the Congregation for Divine Worship authoritatively interprets GIRM 299 to mean that both
versus populum and
ad orientem celebrations are permitted by the GIRM.
