“Hail, full of grace” This translation, approved by the ancient Fathers, agrees with the ancient Syriac and Arabic versions as well.
St. Jerome also had access to the best manuscripts that no longer exist today.- which were much closer to the original manuscripts in Hebrew, Greek and Aramaic than anything still existing today.
In the words of the Greek grammarian J. Gresham Machen, ‘The Greek perfect tense denotes the present state resultant upon a past action’ (New Testament Greek for Beginners, p. 187). The perfect is used in Matthew 4:4,7,10 (‘it is written’). Literally translated, ‘It has been written in the past and is still in force.’ Hence, Jesus expresses the continuing authority of God’s written law by using the perfect tense.
"…Ephesians 2:8, ‘For by grace are you saved through faith…’ The word ‘saved’ is translated from the Greek word sesosmenoi, which is a perfect passive participle. It means that this salvation took place at some point in the past and is continuing on in the present….
In other words, the perfect tense in Greek is a past tense with a special meaning: it is used to refer to a past action which has effects felt in the present. So, here’s what some modern, English-speaking scholars tell us “Kecharitomene” denotes, based purely on the definition of the word and its grammatical usage:
" ‘Highly favoured’ (kecharitomene). Perfect passive participle of charitoo and means endowed with grace (charis), enriched with grace as in Ephesians 1:6 . . . The Vulgate gratiae plena [full of grace] "is right, if it means ‘full of grace which thou hast received’; wrong, if it means ‘full of grace which thou hast to bestow’ " (A.T. Robertson, Word Pictures in the New Testament, p. 14) - Education::Southern Baptist Theological Seminary
“It is permissible, on Greek grammatical and linguistic grounds, to paraphrase kecharitomene as completely, perfectly, enduringly endowed with grace.” (Blass and DeBrunner, Greek Grammar of the New Testament).
Luke 1:28 uses a special conjugated form of “charitoo.” It uses “kecharitomene,” while Ephesians 1:6 uses “echaritosen,” which is a different form of the verb “charitoo.” Echaritosen means “he graced” (or bestowed grace). Echaritosen signifies a momentary action, an action brought to pass (Blass and DeBrunner, Greek Grammar of the New Testament, p. 166). Whereas, Kecharitomene, the perfect passive participle, shows a completeness with a permanent result.Kecharitomene denotes continuance of a completed action (H. W. Smyth, Greek Grammar [Harvard Univ Press, 1968], p. 108-109, sec 1852:b; also Blass and DeBrunner, p. 175).
And our friend’s citation of what the term denotes:
“…to bestow grace, to show favor to someone…the divine favor for a special vocation…” (Fritz Rienecker/Cleon Rogers in their Linguistic Key to the Greek New Testament)
Ironically, that final definition is essentially coextensive with the Catholic understanding of the why of Mary’s sinlessness.
What about St.Sephen being "full of grace in Acts?
Acts 6:8 does not describe St. Stephen as “full of grace” (past-perfect tense). Rather, in the greek, Stephen is described as "filled with grace - “pleres charitos” --present tense, and literally translated as “filled with grace” (at that moment).
The Greek of Acts 6:8 is dramatically different from the Greek of Luke 1:28, which describes Mary as “full of grace.” . In Luke 1:28. Mary is called “Kecharitomenae” --past-perfect tense, and literally translated as “perfectly graced.” or "completed in grace, literally - hence “full of grace”. And so, from the point of view of the original Greek, there is simply no comparison between Luke 1:28 and Acts 6:3.
“Kecharitomenae” is a term exclusive to Luke 1:28, and so exclusive to Mary. No one else in the Bible is described in this way in regard to grace. And this becomes especially striking when we compare it to verses like Ephesians 1:6 and Ephesians 2:8, where Scripture speaks of Baptized Christians as being “graced” -(“a charie toson” --past tense), but never “perfectly graced” or “completed in grace” (“kecharitomenae” --past perfect tense).
And lastly, the most striking difference between Acts 6:8 and Luke 1:28 is that, in Luke 1:28, Mary is being called “Kecharitomenae” (that is “Full of grace” or “Perfectly graced”) as a proper name or title by the Angel Gabriel.
It is amazing how people always overlook that.
Unlike Stephen in Acts 6:8, who is merely being described as “filled with grace and power” (and merely at a given moment - in other words, it is a simple present tense.), Mary is being called - and not only called - but hailed by an angel as “Full of grace” / “Perfectly graced.” And we all know the importance of names in Scripture, right? So, “Kecharitomenae” describes Mary’s very nature because it is presented as her name: “Chaire, Kecharitomenae” —literally: “Hail, Full of grace.”
Matthew 26:49 “to Jesus, and said, Hail, master;”
Matthew 27:29 “him, saying, Hail, King of the Jews!”
“Mark 15:18” to salute him, Hail, King of the Jews!"
John 19:3 " And said, Hail, King of the Jews!"
All of these verses show that a title is given following the word Hail (kai). Just as it is when the angel greeted Mary. Hail, Full of grace!
Acts 6:8 does not describe St. Stephen as “full of grace” (past-perfect tense). And so, from the point of view of the original Greek, there is simply no comparison between Luke 1:28 and Acts 6:3 at all.
The use of the term “highly favoured” is not inaccurate, but at the same time it does not convey the literal and exact meaning of the the grammatical text. So when St. Jerome translated it in Latin as “graita plena”, it was a more accurate and literal translation of the passage.
