Lu 1:28 And the angel came in unto her, and said, Hail, thou that art highly favoured, the Lord is with thee: blessed art thou among women.
Show me the definition of any of the words in that verse that shows as a definition/s for: Immaculate conception.....sinless state... sinless life.
Plus your NABre shows the following as companion verses..
m.[1:28] Jgs 6:12; Ru 2:4;
Jg 6:12 And the angel of the LORD appeared unto him, and said unto him, The LORD is with thee, thou mighty man of valour.
So...if Lu 1:28 teaches Mary was sinless, then Gideon was also sinless!!!!
Ru 2:4 ¶ And, behold, Boaz came from Bethlehem, and said unto the reapers, The LORD be with you. And they answered him, The LORD bless thee.
And....the reapers were also sinless!!!!
