Byzatine Rite stands and even after reception of communion, STAND. Here in Phoenix, an elderly priest died and the next one changed the rubic and posture as you say. Byzatine Rite change missalettes with capital letters and BOLD print stating STAND, DO NOT KNEEL. I never went there again, about 1998? I told my friend, a parishioner of this church, I would not come back. She asked why? I said, I refuse to STAND when it is an honor and a right to kneel and adore Christ truly present. Her reply was, "standing is also a form of mortification". This is a college math teacher and I was shocked. I said, "At the name of Jesus, all knees should bend".
