I just quickly read through the holy father's exhortation. It covers a lot of ground, and is mostly about a proper theology of the Eucharist and the Mass.
Those who expected a series of prohibitions or very specific mandates will be disappointed.
However, it has a lot to say about the Eucharist, which will be skipped over by some, I suspect. (I am skipping over it for the moment!) It does offer support for several aspects of the "reform of the reform":
* preference for Gregorian chant--all music not created equal (42);
use of Latin--priests should learn and use it, and teach the faithful to do the same (62);
* churches should have perpetual adoration (67)
* encourages locating the tabernacle in the apse of the church (69);
Read it for yourselves (just posted) . . .
One has to wonder at some advanced claims about the contents of this exhortation that have not been borne out--that it would offer a sweeping series of mandates concerning the Mass. Likewise, one wonders why the holy father took so long with this letter.
I have a feeling there is more coming from Pope Benedict on the Mass; he has written far too much about the liturgy. But this should be a cautionary tale about relying too much on rumor and speculation.
