In the SSPX, the First Friday votive Mass of the Sacred Heart is not said due to the I class feast.
Outside the SSPX, the First Friday votive Masses may be said: “two Masses of the Most Sacred Heart of Jesus, on the first Friday of each month, in churches and oratories in which special devotions are held on that day in honor of the Sacred Heart” (Rubricæ generales, 385b).
In Masses of the season, the psalm Iudica me is omitted, as well as the Gloria Patri at the Introit and after the psalm Lavabo.
In the SSPX
The Mass of the Seven Sorrows of the BVM is used, as given in the Missal after March 28: White, Gloria, commemoration of the feria, Sequence, Credo, preface of the BVM with Et te in transfixione. For the festal Mass, because it is not de Tempore, the prayers at the foot of the altar include the psalm Iudica me, and the Gloria Patri is said as usual at the Introit and Lavabo.
