:::I believe when I had written that, you had not yet written the "well, take the firstone you mention..." bit. If I was mistaken I apologize.  By silent, I certainly did not intend to imply that you were refusing anything, simply that you had chosen not to comment on that bit.  So as for Gremiale: 
 :::* The article mentions particular liturgical books of the Roman rite, but that does not mean that the use of the articles is specific to that rite; simply that the article was copied from the Catholic Encyclopedia and received little attention since.  The question, it seems to me, is whether gremiales are specifically a RCC vestment, and, as it happens, they are not.  Their use is not an example of "following the RC liturgy"; it's an example of some bishops and priests not wanting to get their vestments dirty.
