There are absolutely no rubrics whatsoever as to the matter; there is no rule in the GIRM as to what you are to do with your hands - palms together, fingers interlaced; palms together, fingers pointing up; hands at your side; arms crossed, or holding hands with the person next to you. Sorry - Archbishop Chaput, when he was archbishop of Denver, put that one to rest. Or at least, he tried to. And he actually knows the rubrics, the GIRM, and Canon law. This bit about it violating the rubrics is an utter impossibility when there are no rubrics to be violated. It keeps popping up; and the challenge is, please state thr rubric which it violates. There is none.
