The Appendix pro aliquibus locis in the Altar Missal I use daily has a Mass for October 23 ... for our Most Holy Redeemer. Next year, I think, I shall use it, not least because the particular devotion goes back to the Great Plague of Venice in 1576 ... which makes it ... you know what I mean ... topical for us in these fun days. There were terrible numbers of plague victims, and so the Doge and the Senate vowed that ... the rest of the story writes itself, doesn't it?
The main Festival in Venice with this title is, as I suspect many readers will know, celebrated on the Third Sunday of July. I believe that quite a lot still goes on, even though it is, I think, some years since the poor things had a Doge. In 1830, Pope Pius VIII marked his brief pontificate by extending the Feast to Rome itself, where it was to be observed on 23 October. Readers lucky enough to have a copy of the splendiferous Calendar published each year by the Redemptorist Community on Papa Stronsay, up near the North Pole, will have noticed that Santissimo Redentore is observed on the Third Sunday of July with greater solemnity, but also appears on 23 October.
That Mass, like so many of the liturgical innovations of the Counter-Reformation, is full of exuberant joy in the wonders of our Redemption ... rather in the triumphalist spirit which animated Rubens' Triumph of the Eucharist. The Introit with which it begins, Gaudens gaudebo ... is from Isaias 61, and the psalmus of that Introit is the majestic, architectural, opening of Psalm 88: Misericordias Domini in aeternum cantabo: in generationem et generationem annuntiabo Veritatem tuam in ore meo. This psalmus is also used in the Votive of the Passion, and in the Sarum (and Ordinariate) Mass of the Five Wounds. And it's there in the Mass of the Most Precious Blood ... and, I think, in a number of other Masses celebrating our Redeemer. (The Mercies of YHWH shall I sing for ever; unto generation and generation I shall proclaim thy hMT in my mouth.)
And the Offertorium, most suitably, is Salus populi ... I am the salvation/health of the people, from whatsoever tribulation they call upon me I will hear them; and I will be their God for ever: Alleluia! You appreciated the pun!
The best response to Coronavirus would have been for the Nation to vow a great Neo-Palladian Basilica to our Beloved Saviour, to be built on the site of that bizarre monument to utter, crass, pointlessness, the "Millennium Dome". Tchaikovsky wrote something which could have been played in connection with its solemn Consecration by Cardinal Burke.
