In 1889, to promote devotion to the Sacred Heart of Jesus, Leo XIII
granted this remarkable privilege that: “in those churches or oratories
where, on the First Friday of each month, special exercises of piety in
honor of the Sacred Heart are, with the approval of the ordinary of the
place, carried out in the morning, the votive Mass of the Sacred Heart may
be added to these exercises, provided that on that day there occurs no feast
of the Lord. or double of the first class, or privileged feria, vigil, or
octave.” [1]
In this votive Mass of the Sacred
Heart, the Glória is recited or sung. If the the Mass is
sung, it will include the Credo, and the solemn tones for the orations,
preface, and Pater noster will be employed. Whether it is recited
or sung, the Leonine prayers may omitted. [2]
This permission was extended in the
rubrics of the 1960 edition of the Roman Missal to allow two votive
Masses of the Sacred Heart on First Fridays when the occurring feast or feria
ranks below the Second Class, and there is no mention of the Mass being
offered in the morning. [3]
In the Old Roman Catholic Church this
rubric is prescriptive. Unless a feast or feria of the First or Second
Class falls on the First Friday, the Mass of the Sacred Heart is to be
offered. The Office, or course, remains that of the occurring feast or
feria.
The clergy of the Old Roman Catholic
Church are incorporated in a Fraternity of the Sacred Heart. [4]
