Among the votive Masses found in the missal are those, as described by Father Fortescue, as "ordered by the pope or the ordinary for certain grave occasions (
pro re gravi)." This includes the Votive Mass for the Election of a Pope.
This Mass may only be offered during the time of
sede vacante. It is said or sung in red vestments. A strict reading of the
rubrics -- #366-368 -- implies the local ordinary must give permission. (Several bishops have already given such permission. In fact, a Solemn High traditional Latin Votive Mass for the Election of a Pope will be offered
tomorrow in Westminster Cathedral.)
Classified a Votive Mass II, a
Gloria is said or sung during a Votive Mass for the Election of a Pope, even in Lent. There is no
Credo on weekdays. Although a Votive Mass II is permitted on Sundays of the second (but not first) class, that opportunity will not come up until 14 April, so the Sunday issue is probably moot. (The Sundays between now and then are each first class Masses.) The Mass may not be offered on Saint Joseph's Day, also a first class feast on 19 March, nor can it be offered between 24 March and 8 April, which are all first class days.
Organ and flowers are permitted, even during Lent, during this
pro re gravi votive Mass. A commemoration of the respective Lenten feria, however, must be made at all such votive Masses (therefore, a second collect, secret and postcommunion using the Lenten propers of the day).
The following are the propers for use in this votive Mass during weekdays in Lent.
