...does not, of course, exist, either in the OF calendar or in the (already heavily and unnecessarily reformed) books of 1962. Except vestigially; the old Octave Day was made the Feast of our Lady's Immaculate Heart in 1944 by Pope Pius XII. One of the changes made in the post-Conciliar Calendar which I find very attractive is the movement of the Feast of our Lady, Queen, originally placed on May 31 by Pius XII in 1955, to this slot. The reasons for associating this observance with the Assumption cycle are too obvious to need spelling out. The great fourteenth bishop of Exeter John de Grandisson (whom old lags in the reading of this blog will remember I have mentioned several times) arranged to have his enthronement on August 22 and (although it was not the anniversary of his death) to have his obit kept on the day following (is such an practice common?). Naturally; he was a devoted client of our Lady, particularly under the title of Mater Misericordiae, and his devotion dseems to have been very much along the lines of that recommended by S Louis Grignion de Montfort. Incidentally, that is why in the Ebbsfleet Calendar August 22 is, in Devon and Cornwall, a Festum and not just a Memoria.
I suppose an unofficial observance of the days within the Octave is contrary to current rules both in OF and EF; votive masses of events in the life of our Lord and his Mother are, with the exception of the Immaculate Conception, not allowed. One could, however, say ordinary votives of our Lady. In the C of E, of course, things are more flexible. Yesterday I said the old Gaudeamus mass of the Assumption, the one superseded in 1950. It makes the point I referred to in my earlier post about the Assumption: that we ought to see that mystery in terms of our Lady's mediatorial role. The Collect: it is Mary's intercession we need to be saved;the Secret: she has migrated so that we may sense her intercession in heavenly glory; the Postcommunion: it is by her intercession that we pray to be delivered from a cunctis malis imminentibus.
