I definitely see the differences but on the kneeling thing, I close my eyes and "every knee shall bow" always goes through my head. It is particularly strong during the Consecration and after Holy Communion (receiving Him as well, but if I knelt, I'd probably be thrown out!) as you know what Catholics believe about the Real Presence. Believing as I do, how could I not kneel?
I was just ironing and heard the first few minutes of today's Mass on EWTN (the noontime broadcast) and the priest started out by explaining "Sacrifice of the Mass" and what it is and what it is not. I thought of you, fishtank, and hope you will avail yourself for 5 minutes and listen - and learn what Catholics believe the Mass is and not what you personally believe the Mass is. It will be rebroadcast (streaming and on TV) at 7 PM and Midnight tonight. Just 5 minutes - right after the priest files into the Church and before the Mass even starts. I gave you the link in my last post to you. Here it is again: EWTN streaming.
