How is she not?Sheer speculation, and without reference.
Have you borne God lately?
So?
So, God required the Jews to make this wonderous man-made creation in the OT, known as the Ark. He commanded that the Covenant be kept in the purest gold, and those who touched it unworthily were struck down. And this was just the creation of man to house the Old Covenant. But, with the new Covenant, God chose a regular vessal? A woman who supplied the Christ with his Sacred Blood?
Why would God demand near-perfection to house the Old Covenant, but would not do the same with the New Covenant? She is the height of Creation because God's ability to sculpt and create far surpasses that which can ever be done by the hands of men.
