Except Saint Jerome, who new Greek better than you Mr Internet self professed ex Catholic theologian and he indeed translated the passage as “Ava Maria plena gratia”. So did Jerome not understand the nuances of the style of Greek that the NT was written in and it took Protestants, and in particular, American protestants 1,600 years to figure it out.
And again, you miss the point, Mary received God’s Grace before the Incarnation, the passage in Eph 1:6 is being written some 25 years after Christ passion and resurrection, which is precisely the point I was making. God did, in a special way, provide Grace to Mary before Christ became incarnate and died and rose from the dead, for all the NT you site, those individuals received God’s Grace after Christ paschal mystery. That is a distinction that you miss and don’t want to deal with.
This simply is another example of the problem. As the RC must support Rome, so he/she uncritically follows men when they do so, and resorts to ad hominems and the unScriptural premise that unlettered men cannot be correct refuting scholars.
Yet i have already exposed Jerome as wresting Scripture to support his denigration of marriage (Gn. 2: "two is not a good number because it destroys unity, and prefigures the marriage compact. Hence it was that all the animals which Noah took into the ark by pairs were unclean. Odd numbers denote cleanness"), while it remains that in the Greek "full of grace" would be "plaras karitos" but i in Luke 1:28 it is "kexaritomena" which means "highly favored one," or graced, which the DRB inconsistently but rightly uses in Eph 1:6.
And evidently the translators of the official Catholic NAB Bible also thought they knew Greek better than Jerome, as they also render Lk. 1:28 as "Hail, favored one!"
,In contrast, the only one (though Stephen in Acts 6:8, in some mss) said to be full of grace is the Lord Jesus, "full ("plērēs) of grace (charis) and truth," (Jn. 1:14) using "plērēs," which denotes "full" 17 other places in the NT
Do not be like the scorning Pharisees, "Are ye also deceived? Have any of the rulers or of the Pharisees believed on him?" (John 7:47-48)
