The Ordo is a detailed compilation of the rubrics for assisting the priest in the offering of Mass and the recitation of the Divine Office. It is in Latin, and due to the length of this work, much if not most has been set down in a Latin abbreviated form.
The rubrics followed are that of St. Pius X for the Universal Calendar of the Church. However, feast days proper to the United States have been added. The traditional rubrics for Holy Week (pre 1956) are observed.
