Of course. But my Bishop is not changing the GIRM, merely adding something to the Mass that is neither prescribed nor proscribed by the GIRM.
The GIRM and RS are very specific on where such things should be. By not following the perscriptions he is altering the GIRM and RS.
Does the GIRM perscribe break-dancing (I know this sounds silly), but does it? The GIRM and to my knoweldge RS does not forbid it, so can a Bishop add break-dancing.
General Instruction of the Roman Missal 24. The priest must remember that he is the servant of the sacred Liturgy and that he himself is not permitted, on his own initiative, to add, to remove, or to change anything in the celebration of Mass. Cf. Second Vatican Ecumenical Council, Constitution on the Sacred Liturgy, Sacrosanctum Concilium, no. 22.
The GIRM prescribes silence after the homily, nothing else, silence. Then come the Credo and Prayer of the Faithful.
If I can’t follow my Bishop on this matter, why should I follow him on anything else that is not simply repeating something general the Vatican says?
So if a Bishop makes a little mistake, we should lose confidence in him? It’s not as if he is supporting abortion or dithering on child protection.
We are talking specifically about the liturgy here, not the general function of Bishops in the daily running of their diocese. On some things however, the Vatican has norms that must be followed.
Now some things Bishops have power like not having altar girls, but on the specific issue we are talking about the GIRM and RS are clear cut. The GIRM makes sure there is a uniformity at Mass and the ruberics are followed. RS adressed specific abuses in the celebration of the Eucharist.
