I have faith God can and does preserve His word throughout many languages and translations.
Of course He does: He is Father to all mankind. God speaks to all men, presumably in the language they understand.
And I also absolutely agree that the knowledge of the Greek language is not a necessary prerequisite for understanding Scripture.
But the Greek language imbeds certain philosophical ideas that survive to our own day that do not easily lend themselves to modern translation. There is a Christian tradition, the elaboration of Christian philosophy, that perhaps originally came from/through Saint Justin Martyr, who initially viewed Christian theology through the lens of classical Greek philosophy. But far more than that, Justin evidently "fell" for Christianity in the same way Augustine would "fall": as not only the perfection of the rational human mind in Our Lord Jesus Christ; but more, the perfection of the individual human life, the human soul, in the present and its beyond in eternity, in and through Him.
So philosophy gives a narrow view of course; but Justin is complemented by Saint Paul's experience and testimony, arising in part from his Hebraic roots, perhaps profoundly affected by the experience of having been blown out of his saddle, left stunned, dumb, and blind for days: thus the Roman Jew Saul of Tarsus' experience of the Rauch of God, on the road to Damascus.
In these two men, Athens and Jerusalem met and, arguably, have never since parted.... IMHO FWIW (figuratively speaking of course)
Christ came to fulfill the Law of the Prophets, then to institute a new dispensation of divine law that relied on their insights, God's direct communication through Moses; yet God resolved the ten several into two final principles, both of which have "love" as the active verb.
Jesus Christ fulfilled the Prophets. By the same token -- divine Justice -- I do not see why he did not also fulfill the great Greek Philosphers....
God is Love. God is Truth. God is Justice.
Good night, dear sister in Christ! May His blessings be ever with you and all of yours.
