Theotokos is "the birthgiver of God". This is a far different meaning than what is being applied here as the "mother of God" which implies far more grandeur.
You're ok with birthgiver of God, but not mother of God. It would seem to wish Mary gave birth, then walked away without mothering the infant Jesus or caring for her son or weeping at His death.
To me, the Incarnation is a major, if not the major, defining moment for Christianity. And the Word became flesh and dwelt among us. Jesus became like us. He underwent torture, pain, ridicule; the Passion of Christ. All this is not diminished by the simple fact that He also had a mother - like us.
So, I honestly don't get it.
Yes, birthgiver indicates precisely what Mary did, she was the chosen vessel to give the physical birth to our Lord. That includes all the responsibilities motherhood implies. Quite frankly it would have been far easier for Joseph to walk away than Mary.
"Mother of God" implies Mary is was so much more than just a birth and care giver. Salvation depended upon Mary for she was the Mother.
Would you say Mary was sinless in contradition to Rom 3:23? I think you do get it.
How would you rank the Resurrection in comparison?
