MDO, lately in your posts, you present made up things as if they are true, and then use them to build further 'truths" on that false foundation.
This attempt to spin straw into gold clearly demonstrates there is no support in Scripture and no support from a single Apostle about what you are trying to defend.
Scripture says nothing that supports Mary's body belonging to God.
Nor does any doctrine of Christ, nor doctrine of salvation depend on Mary remaining a virgin.
If we are to believe all God says about marriage, Mary's body belonged to Joseph alone - for mutual enjoyment with Mary and for sex within their marriage.
Mary’s confusion over the angel’s announcement and message certainly uts into the fantastic claims Catholics make about Mary’s alleged vows.
The way they talk about Mary, everyone knew she was special and set apart for some sacred holy purpose, and yet nothing in any account relating to her in Scripture, especially regarding how she and others i teracted, ever suggests that anyone ever thought she was ore that the carpenter’s wife, herself included.
When the angel greets her with “ Hail, you highly favored one” she wonders what kind of greeting it was and what it meant.
Not a good indicator that she was sinless from birth, consecrated to God, and knew it.
