I would like to hear Thomas’ answer to the points made by Canto and others. As I understand Thomas’ position, he agrees that GIRM prohibits the laity from giving the homily, but dismisses this as irrelevant because we are talking about a layman giving a talk after the homily. And he is correct that GIRM doesn’t say “no member of the laity shall give a talk after the homily.” But as Canto has pointed out, GIRM does prescribe a sequence of events: homily, reflection, creed,
Why, then, does the interposition of anything between the homily and the creed—except as otherwise specifically provided—violate GIRM’s prescription of a sequence, no less than would doing something explicitly forbidden? As others have pointed out, a five minute interval of liturgical dance is not provided for after the homily, so surely GIRM prohibits it—implicitly rather than explicitly, yes, but no one would suggest that a law must enumerate not only what it prohibits but also what it allows.
Thomas’ position seems to be built upon two convictions (although I may have misunderstood, and apologize if I have). First, that anything that the GIRM does not explicitly direct, either by mandate or prohibition, is confided to the discretion of the bishops. And second, that the sequencing in the rubrics is binding only insofar as the temporal relationships of its components are concerned. That is, Thomas seemingly posits a rubric where the homily-reflection-creed sequence is binding insofar as the homily must come before the creed, but which does not preclude other things happening in between those items. Canto, by contrast, thinks that the sequencing is binding not only as to the sequence of the stated objects vis-à-vis one another, but as to what items take place at all. (For the record, I think Canto is correct.)
Would you mind speaking to those things as a way of moving the conversation forward?
