How very ruthless of the post-Conciliar 'reforms': Westminster Cathedral, overnight, lost its Patronal Festival when the 'reformers' reduced July 1 from a Double of the First Class to a feria on the almost sacrilegiously flippant grounds that the Precious Blood would get a perfectly adequate 'covering' by being merely added to the title of Corpus Christi. Maestissimi homunculi. Thus a gorgeous piece of B Pius IX liturgy disappeared: the Solemn Festival he had placed on the calendar to commemorate his return to the City after the Roman Revolution of 1848. (There is nothing vulgar, incidentally, about doing that sort of thing to the calendar, or, if there is, it is simply the vulgarity of an incarnational religion. Byzantine calendars are richly and very appropriately peppered with such observances related to events in Christian history.)
Good news, however: the Ordinariate Church South of the River, Precious Blood Southwark, keeps its patronal festival on the proper day, today.
Incidentally, on the same occasion B Pius IX also raised our Lady's Visitation from a Greater Double to a Double of the Second Class. Urban VI had fitted that festivity onto July 2 as a prayer for Unity. It was the first day available after the Octave of S John, and had long been, among Byzantines, the Feast of the Deposition of the Protecting Robe of the Theotokos in the great Basilica of Blachernae in Constantinople. All that, even the Ecumenical relevance of it, was treated in the post-Conciliar 'reforms' as so much extravagance to be shovelled away: and so the Visitation had a more 'logical' date discovered for it.
B Pius IX's original date for the Precious Blood had been the First Sunday in July. It was the reforms of S Pius X that shifted the Festival onto July 1. S Pius X's liturgists felt, in my view rightly, that too many of the old Roman Sunday Masses were unused on their Sundays year after year because so many much newer feasts were permanently anchored on "the xth Sunday of such-a-month". S Pius X's change did not, of course, mean that the Precious Blood never fell upon a Sunday; it meant that it only fell on a Sunday once every six or seven years. And, with a pastoral flexibility which characterised papal liturgical interventions before the fateful, deplorable collaborazione between Pius XII and Hannibal, S Pius X still allowed, for pastoral reasons, all the Masses on the First Sunday of July to be of the Precious Blood even when July 1 fell on a weekday.
For those of us who so wisely use 'the Old Breviary' today has superb Office Hymns (their authors, sadly, unknown). The one provided for Lauds relates particularly well to the old English devotion to the Five Wounds. The English Catholic Hymn Book gives the Vespers hymn Festivis resonent in translation; a great majestic hymn in striding all-conquering Asclepiads, a monument to the triumphant Counter- Reformation and the rediscovery of Catholic self-confidence under B Pius IX. Anyone who's interested in its metre will find an article of mine at 19 March 2019. (Viva viva Gesu, of course, appears in modern hymnals as 'Glory be to Jesus'.)
During the Month of the Precious Blood, perhaps the Litany authorised by S John XXIII could be dusted off and given an airing ... I wonder if any Byzantine poet has ever composed a Paracletic Canon in honour of the Precious and Life-giving Blood of our Most Holy Redeemer.
