I understand your point Brother… and I understand the rites are different… Mind you that we are helping each other out here and that I’m merely pertaining to the Tradition of the Latin Rite Catholics…

in a way, we are kind-of debating… But it’s all for our own good as well… True enough that the body position does not determine if we will have Salvation…
Since we are humans, and God is human as well (Jesus Christ) and He understands what humans feel and do and act and perform… etc
THEREFORE, we must also treat God like a human, in the way that we treat humans…
God is the King of Kings, King of all universes and all that encapsulate universes. He is the Royalty of Royalties.
To treat the God like royalty, we must base upon what we humans personally do to human royalties…
With that in mind, we have to make our love (feeling,doing,acting,performing,etc) for God personal as well…
THEREFORE, if we bow down to human royalty… WE SHOULD DO MORE for God!
It is kind of personal because, you can lay flat on upon the floor for human-sinning-royalties… BUT you cannot simply single-leggedly-kneel down to God!
They say it’s not personal… HEY! I F YOU WERE GOD… AND YOU SAW THESE PEOPLE KNEELING DOWN TO MERE SINNING-HUMAN-ROYALTY AND THEY COULD NOT KNEEL TO YOU DURING WORSHIP… WHAT WOULD YOU THINK ?.. WE CAN FEEL THAT GOD IS HURT … RIGHT ?

The Old Testament talks a lot about this ! Our God is a human God. He has feelings too!
If I use your observation/opinion, God would say… "Hey it’s ok even if you don’t kneel to me. After all, WHO AM I TO YOU ANYWAY ? "
