The very fine live between veneration and worship is not really something I'd care to debate either. The real point of debate is not that but the source of Marianism. It simply is not from the bible. Therefore what we are debating is the validity of a religion that calls itself Christian yet has doctrines that are not biblical.
Yet another thought just occurred. Paul was given a thorn in his side. Why? So that people wouldn't "venerate" him too much. Paul was an awesome apostle and gave us, obviously through the Holy Spirit, so much of the NT. But God doesn't want man, living or dead, to be "venerated" or any of the other words you can get from a theausaurus(sp)that are equivalent. So not only is Marianism not derived from scripture, it is contrary to yet another piece of scripture.
I was reading in John yesterday and it occurred to me that the Gospel that speaks to the diety of Jesus speaks the very abolute least of Mary. RC's clain that Mary is the key to knowing Him better including his Diety hence her name MOG, and we see the opposite in scripture.
Oh how it frustrates me to see probable Christians led astray down a rabbit trail of Mary "adoration, veneration...etc".
