I concur with your analysis.
I also find it much more complementary of Mary to recognize her as a human sinner with an old sin nature, whom God still found to be appropriate to fully bless as the mother of our Lord and Savior Christ Jesus.
Those who swear she was sinless and the Mother of God, will find themselves trapped into also labeling her as the Whore of God come judgment day if it be revealed she ever had sexual relations with her husband Joseph.
Of course those who do not so worship her, can fully accept her having been fully blessed by God to be the mother of Christ Jesus and still be a woman married to Joseph who later bore him many children.
After Adam, we all fall into a category of sinners. If there are humans who do not, then there are far larger theological issues to consider, namely the possible loss of salvation for all other sinners who rely only upon Christ for salvation, rather than obedience to the Law.
The Marion worship is far more deceptive than it appears to simply be an adoration of innocence.
So true...Where's the miracle of the incarnation if Mary was some rogue, sinless creature who was not one of us???
