As if the Holy of Holies would allow himself to be borne of a sinner.
OK, so we remove "For all have sinned and have fallen short of the glory of God" (Romans 3:23) because we now have an exception - and an exception based not on fact, but on wishful speculation.
Look how the ark of the covenant was treated. It was very well respected.
Yes, we see how it was dragged out into a field of battle, thinking that the Ark had magical properties in and of itself, then being captured and treated like an object of worship by the Philistines. Because we all know that God really detests worship of Him and prefers that we cast our affections on things of wood and metal.
I know that non-Covenantialists can't understand the prophetic languages and types concerning the temple, yet let me ask you this since you have tried to associate the two: Regarding Solomon's Temple, where the Ark and the Shekinah Glory resided for a time, was that Temple and that innermost room built by sinners or did angels descend from heaven and build it?
Now revisit your argument and explain how sinners and reprobates can build a Temple for God's Glory (which is arguably the most important thing of all) yet Mary had to be sinless. For extra credit, how could Mary be sinless, born of the seed of fallen man and a soiled womb, but the Creator couldn't, and how this doesn't evolve into a impossible regression that ends with a fallen Adam & Eve.
Mary is the living ark who bore the God-Man. She deserves respect
Then we should also worship Mary's parents since Mary would not have been around if not for her parents, and her grandparents, branching the tree wider and wider through the prostitute Rahab who must also be respected. Arguably, if not for Adam & Eve there would not be a Mary, so we should also pray to them (even if they are burning in Hell).
Has the word "respected" now been redefined into "worship"?
