text: I find nothing in Sacrosanctum concilium that contradicts what I've indicated above.  By the way, the dictionary definition certainly comports with my understanding of "participation": "A state of being related to a larger whole", "a sharing, as in benefits or profits".  If the "active" in "active participation" must refer to only some physical manifestation, as you seem to imply, one may only guess that you do not believe in "active listening".  Perhaps you should broaden your definitions before accusing an interlocutor of error.
