I have read the GIRM and Redemptionis Sacramentum several times so I think I know what the answer to my question is gonna be. But, I may have missed something so I will ask it anyway.
There is a local parish that has institued a “Stewardship Prayer” after Communion and before the final blessing. Is there anything at all in any Church documents that might make this licit?
I am aware of GIRM 24 which states, in part:
“Nevertheless, the priest must remember that he is the servant of the sacred Liturgy and the he himself is not permitted, on his own initiative, to add, to remove, or to change anything in the clebration of Mass.”
That would seem to settle it unless there is something somewhere that allows a priest to insert a prayer at that point in Mass.
