Can you cite any sources for this? After all the Greek bishops which came together in the 7 councils were pretty good speakers of Greek. I think they'd know what words meant.
The Hebrew root which is interpreted saint, also meaning holy or sanctified, is chaciyd.
Further meanings attached to the word saint originate from the doctrines and traditions of mortal men: Etymology of Saint
Personally and for cause, I eschew all the doctrines and traditions of mortal men:
Ye shall not add unto the word which I command you, neither shall ye diminish [ought] from it, that ye may keep the commandments of the LORD your God which I command you. Deu 4:2
For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: - Rev 22:18
But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God. Matt 4:4
I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.
The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have [it] more abundantly.
I am the good shepherd: the good shepherd giveth his life for the sheep.
But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth them, and scattereth the sheep.
The hireling fleeth, because he is an hireling, and careth not for the sheep.
I am the good shepherd, and know my [sheep], and am known of mine. As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep.
And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, [and] one shepherd.
Therefore doth my Father love me, because I lay down my life, that I might take it again. No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father. John 10:7-18
Saying it three, count 'em, three times puts the commandment in "flashing neon" importance.
So I ignore the doctrines and traditions of mortal men and feed on every word that proceeds from the mouth of God - including the Living Word of God, Jesus Christ Himself. (John 1, Rev 19, John 6)
Should be easy to google info on this..
Most all greek scholars know this.. at least the older ones..
Maybe older non Roman Catholic ones..
I use Kenneth Wuest's "Golden Nuggets" from the Greek as a source..
Might hard to find that volume these days though..
Very special insights on many greek words.. christian wise..
Actually the Greeks had no word for "Christ/Messiah" in the Hebrew sense either.. one had to be invented.. Interesting display on how that word happened also.. Ancient Greek was and is a very rich language (in meanings) but certain concepts were foreign to the Greeks.. and actually everybody else but the Jews.. No doubt translating to other languages (of the time) had the same problem.. But I learned of this "problem" from Kenneth Wuest..
