It’s what you’re lexicons are translating as “highly” that signifies “completely.” But thanks for contradicting dart user who is falsely claiming that it’s all simply the present tense of “charitou.”
The obvious difference between Christ and Mary is that Mary has received grace from Christ, where Christ possesses his own grace.
dartuser claimed nothing of the sort ...
No where in Scripture is Mary ever given anything other than a position of being favored, or blessed, as the Mother of the Messiah.
She acknowledged she needed a Savior in Luke 1:47. Either she was born in sin, or she was a liar. Either way she sinned.
The only one ever referred to in the Greek text as 'full of grace', i.e., without sin, was Christ.
