Among other things, it recommends the use of a Mass for Various Needs:
The Roman Missal provides a Mass formulary for a Pope. It can be found in the section, “Masses and Prayers for Various Needs and Occasions: 2. For the Pope.” This Mass is permitted, with white vestments, on weekdays in Lent “at the direction of the Diocesan Bishop or with his permission” (General Instruction of the Roman Missal [GIRM], no. 374), but not on the Sundays of Lent.There are no musical settings for the antiphons given in this Mass. For those who would like to sing these antiphons in simple English chant, please consider the following musical settings (free download):
In addition to the full text of the Entrance Antiphon, a shorter refrain is offered at the end of the Psalm that can be sung by the congregation.
Let us all indeed pray for our Holy Father during this time of transition for him and for the Church.
(Antiphon texts are taken from the 3rd Edition of the Roman Missal, and Psalm verses are taken from the Revised Grail Psalms.)
