Jesus Christ, being the second person of the Blessed Trinity, sent His angel to call her full of grace and select her to be the Mother of God.
You left that off of your list.
And it seems to me that is ample honor for anyone - all the justification needed to call her “blessed”!
But when a woman tried to focus attention on Mary as special, Jesus replied, “Rather, blessed are those who hear the word of God and observe it.”
That is the point the Protestants are trying to make. If you wish to believe in the Assumption - well, it neither says yea or nay in Scripture, and I have no personal knowledge, so believe as you wish. I would say the same to the Orthodox - where scripture is silent, believe as you wish and let God teach us on His schedule.
Unfortunately, your church claims I MUST believe in something not mentioned in scripture, nor by anyone during the first 4-500 years, or risk damnation.
Mary was chosen to be the vessel of birth for God - what more honor does anyone need? But OUR focus should be on God, and obeying Him. As we draw close to God, we will draw closer together.
