For example, what if a priest so desired to say a Mass in private for a personal intention , for example, a votive Mass for his parents.
How would he go about saying the Mass if he did not have servers and lectors? If so, does the priest read the readings and opening prayer,and confession himself at the altar and then proceed into the Liturgy of the Eaucharist?
Does he make the responses himself?
Does he have to say such Mass in a low voice or does he have to read,for example, the Eaucharistic prayer in a loud tone.
In short what are the changes in rubrics if he is doing the Mass without a minister and the GIRM does not have rules for a solitary Mass of the priest?
