100. "Pastors of souls should see to it that the principle hours, especially Vespers, are celebrated in common in church on Sundays and on the more solemn feasts. The laity, too, are encouraged to recite the divine office, either with the priests, or among themselves, or even individually."
101. (1) "In accordance with the age-old tradition of the Latin rite, the Latin language is to be retained by clerics in the divine office..."
It goes on, of course, (by way of exception) to permit the vernacular, but the Latin is the norm.
There are practically no churches in the world (never mind Cathedrals) which are fulfilling Vatican II in this respect, in the Ordinary Form (in Latin!).
If you find a church that has it: e.g. Holy Innocents, NYC, it is in the extraordinary form.
Thanks be to God and to the Traditionalists for faithfully implementing Vatican II, where our bishops and priests are sluggish!
Instead of trashing the tradition Pope Francis and Cardinal Nichols, and company, should get busy implementing Vatican II in the ongoing Reform of the Reform, in accord, not with personal preferences, but with the liturgical norms of the Church.
N.B. In this regard, when will the Graduale be taken off the index of forbidden books of seminary and priestly worship? never mind of Catholic parish celebrations? There are many bishops very much in line with Pope Francis who categorically forbid the use of Latin chant at Mass or otherwise, while the 2005 GIRM is filled with references to this normative liturgical music. That, at this juncture, is simply infidelity to the Catholic liturgy: e.g. Archbishop Cupich Installation Mass, though many languages were used, not one word in Latin! Typical of cathedral liturgies.
