I believe most friars have already received a direct mailing of the new Calendarium Ordinis Praedicatorum, approved by the Congregation for Divine Worship on April 14, 2019, and promulgated by the Master of the Order, Bruno Cadore, on June 24. I have made this document available for download here for those who wish to celebrate Dominican Saints with the new Roman Missal and the Liturgy of the Hours. Note that those who wishing to celebrate the feasts reduced to optional memorials may still do so--they are optional.
The format of this document makes it difficult to identify the changes promulgated, so I will summarize them here. The list of Dominican feasts is not much changed, but a good number of previously obligatory memorials have become optional, and there are some changes in the dates of celebration. Here is a summary:
Change from obligatory to optional memorial:
4 January – St. Zdislava Berkiana (28 November in the U.S.)
18 January – St. Margaret of Hungary
4 February – St. Catherine de’ Ricci
10 May – St. Antoninus of Florence
19 May – St. Francis Coll Guitart
9 July – St. John of Cologne and Companions
18 September – St. Juan Macías
28 September – Ss. Dominic Ibáñez de Erquicia, James Kyushei Tomanaga, Laurence Ruiz, and Companions
9 October – St. Louis Bertrand (obligatory memorial in Western Province as secondary patron)
Change from obligatory to optional memorial with new date:
15 January – Ss. Francis de Capillas, Peter Sans, and Companions, moved to 9 July
6 November – Bb. Alphonsus Navarrete and Companions, moved to 28 September
New optional memorials:
4 July – B. Pier Giorgio Fassati
6 November – Bb. Bonaventure Garcia Paredes, Hyacinth Serrano Lopez and Companions
Removed from the Dominican General Calendar:
12 February – Bl. Reginald of Orleans
28 April – St. Louis de Montfort (still an optional memorial on the Roman Calendar)
21 May – Bl. Hyacinth-Marie Cormier
10 June – Bl. John Domnici
17 July – Bl. Ceslaus of Poland
The Order also published a revision of the list of Dominican Saints and Blesseds that are optional memorials, but only in the provinces where they lived. The four blesseds removed from the general calendar just listed are now approved for local use as below. Note that none of these optional local blesseds (of which there are many others) are celebrated in the United States. Here are those changes:
Add to local calendars:
12 February – Bl. Reginald of Orleans (France)
1 April – Bl. Joseph Girotti (Italy--St. Dominic; Austria-Bavaria)
16 May – Bl. Valdimir Ghika (Vicariate of Eastern Europe)
21 May – Bl. Hyacinth-Marie Cormier (Italy--Roman)
10 June – Bl. John Domnici (Italy--Roman))
17 July – Bl. Ceslaus of Poland (Poland)
7 September – Bl. John-Joseph Lataste (France)
9 December – St. Narcisa of Jesus Martillo y Morán (Peru)
Date changed on local calendar:
25 September – Bl. Mark of Modena (Italy--St. Dominic), moved to 20 September
Note that these changes become effective on the First Sunday of Advent, 2019 and that for those celebrating the Dominican Mass and Office of 1962 under the provisions of Summorum Pontificum and Universae Ecclesiae, the only changes implied by this would be for those who want also to celebrate Dominicans canonized or beatified after 1962. When I publish the Dominican Rite Calendar for 2020, I will include these changes.
