Are the senior Archangels punsters? S Gabriel certainly was; he hailed our blessed Lady with the words Khaire kekharitomene (incidentally I consider it highly probable that the Holy Family, and the Twelve, were Greek-speaking).
The second of those two words is a Greek perfect participle passive. Perfect participles in Greek refer to a present state which is the result of a past action (like our English expressions "the married" and "the dead"). So the word means that Mary is a having-been-graced-person; as the result of her Immaculate Conception (in the past) she is (now) crammed full of grace. Christine Mohrmann tells us that "several early translations, the North African Codex Palatinus (e), as well as the European , perhaps Illyrian, translation of Codex q29, render the words of St Luke ... by ave gratificata!
This Latin word looks exactly like a Latin equivalent of that Greek perfect participle passive. Mohrmann points out that words formed like this "were very popular in Early Christian Latin ... [i]n this way, one single word was sufficient to reproduce the full meaning of the Greek ... one cannot dismiss the early Bible translations as clumsy products of semi-literates, as is too often done in Classically minded phililogical circles."
It is, I am sure, no coincidence that the next paper in this Collection, Volume III of Mohrmann's collected papers, is her deservedly celebrated 1947 hatchet job in Vigiliae Christianae on the disgraceful new translation of the Psalms concocted by Cardinal Bea at the instigation of Pius XII. She quotes Bea's words advocating "Una Traduzione latina dei salmi che ... si attenga al vocabulario, alla grammatica e allo stile di quel migliore periodo della latinita", i.e. the Augustan period.
I'm sure they used to say in German seminaries, "Sancte Tulli, ora pro nobis" and "Sancte Horati, ora pro nobis.". I wonder what they say nowadays.
