Hos Corpus Christi Watershed kan vi lese at en biskop i USA har nektet alle feiring av messen ad orientem i sitt bispedømme, men et dokument fra Vatikanet fra år 2000 nekter biskoper å komme med slike bestemmelser:
When the 2000 (2002) Missal was promulgated, the Vatican’s CDW was asked whether bishops have authority to forbid “ad orientem” celebration. Dated 10 April 2000, the CDW response was unequivocal:
HIS DICASTERY [i.e. the Vatican’s Congregation for Divine Worship] wishes to state that Holy Mass may be celebrated versus populum or versus apsidem. Both positions are in accord with liturgical law; both are to be considered correct.
There is no preference expressed in the liturgical legislation for either position. As both positions enjoy the favor of law, the legislation may not be invoked to say that one position or the other accords more closely with the mind of the Church.
This letter (PROTOCOL NO. 564/00/L) specifically addresses whether a bishop can forbid “ad orientem.” They stated that, while exercising his rightful role as “moderator of the Sacred Liturgy in the particular Church entrusted to his pastoral care,” the Diocesan Bishop can neither “exclude nor mandate the use of a legitimate option.”
This letter was sent by the same congregation responsible for drafting the 2000 (2002) Missal and GIRM, which was approved by Pope St. John Paul II. The letter was signed by Cardinal Medina, CDW Prefect, and Archbishop Tamburrino, CDW Secretary. I have no idea why so many people commenting on this issue refuse to make reference to it.
