The Bible teaches that Mary was "full of grace" (the literal meaning of the angel's greeting to her) and she herself, under inspiration, said "all generations to come shall call me blessed".
That's a bit more than just a "good woman honored of God". Sarah was a "good woman honored of God," but nobody ever said anything like that about her.
She's not a goddess, she's a redeemed and glorified human being. She's "deified" in the sense that all the glorified are "deified": they are made partakers of the divine nature, see 2 Pt 1:4. Religions which teach more than that are idolatrous; religions which teach less than that contradict Scripture.
Even today we are admonished to honor those who follow God's word. I have the deepest respect for Mary. We are indebted to her for bearing and raising Jesus, but I think her selection to be Jesus mother was the pinicle of her existance. I am certain she would agree.
Let's also consider this. If Jesus received any special treatment above and beyond that of a normal human child, it could be stated that he obtained an unfair advantage making it possible for him to attain pefection. Having a perfect mother would have validated such a claim. Jesus had to deal with human frailties, just as you and I.
In one spot in the Bible I believe Jesus stated that He had no more access to special powers than those available to the common man. The Holy Spirit is there for US. And we have access to Jesus even as He had access to God through prayer. Jesus only had God the Father to pray to, a being that hadn't lived as one of us, or experienced our existance.
This is a very powerful concept that most of us overlook. It also lends itself to the idea that man can and should live near a pefect existance. I do not feel that man will live a perfect existance until Jesus comes to call us up into the clouds with him, but I do believe that our probation will close before Jesus arrives back to collect us unto Himself. Those who are translated without seeing death will have been purjed of sin before that moment. IMO
