About this Ordo

The Roman Rite as in force prior to the changes of Leo XIII

Ordos are no longer printed for these rubrics. This one is made to fill that gap: a working ordo for the Roman Rite as it was kept under Pius IX, from 1846 to 1877, under the Tridentine books and rubrics, before the changes of Leo XIII, who came to the throne on 20 February 1878. One liturgical state is applied to every day shown here, and it is worked out for the present calendar.

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

Every rule was read from the printed books of the period, and where sources disagreed the difference was traced before anything was changed.

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 printed in the books of Pius IX’s time. In practice this means:

What Leo XIII changed later, which is not here

The printed rubrics of Leo XIII’s pontificate differ from those of 1846 and 1872, and the changes that came after them altered more. None of it is applied in this ordo:

The ordo is built from the rubrics and the printed sources of the period, and each rule has been checked against them. If you find a day that differs from a book you hold, or have a question, write with the date and the book or page.
