About this Ordo

The Roman Rite as in force prior to the reforms of Pius X

Ordos are no longer printed for these rubrics. This is one for the Roman Rite as it was kept from 1900 to 1911, under the Tridentine books and rubrics, before St. Pius X’s Divino Afflatu reform took effect on 1 November 1911. Those rubrics are applied here to the present-day calendar.

Pope Leo XIII (1810–1903), elected 20 February 1878, pope for most of the period this ordo covers.

What it is

The Office and Mass of each day are computed from the rubrics themselves: which feast is kept when two fall together, what is transferred and what is omitted, the octaves, the commemorations, and the concurrence of Vespers, with the Mass, colour, Preface, Gloria and Credo, and the hours of the Office that follow from them. It is an ordo for the universal Roman calendar, made for those who keep, or wish to follow, these rubrics.

Local and particular material is not shown: diocesan and religious proprias, the Proprium Cleri Romani, and feasts peculiar to one country. Where a printed directory of the period gave such a feast, it was recognised as local and left out. The reigning pope, Leo XIV, is named only for the anniversary of his coronation.

Sources

The rules are taken from these books and directories of the period:

The printed ordos give the local feasts of their own countries, which are left out here; where no second directory covers a day, the rubrics and the Kalendarium decide it.

The Tridentine rubrics

The rubrics followed are those of the Breviary and Missal of St. Pius V, as revised by Clement VIII and Urban VIII and as applied by the decisions of the Sacred Congregation of Rites down to 1911. In practice this means:

What Pius X changed later, which is not here

The Apostolic Constitution Divino Afflatu (1 November 1911) and the rubrical changes that followed it altered much of this. None of it is applied in this ordo:
