Jesus already validated the Septuagint Canon by using it and sayin For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Whether there were Scriptures in Hebrew and Aramaic does not profit you if you cast away the received Hebrew and Greek text we do have. If you exclude the Holy Spirit from preserving the Canon we will see another new sect, cult, heresy, or re-formed religion. Yeshua said this to the Jewish Apostles who discipled others to build Yeshua's ecclesia But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
Regarding many of the debate comments : For, brethren, ye have been called unto liberty; only used not liberty for an occasion to the flesh, but by love serve one another. For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself. But if ye bite and devour one another, take heed that ye be not consumed one of another.
Jesus was even more descriptive here on what we call the OT canon:
Luke 24:
25 Then He said to them, O foolish ones, and slow of heart to believe in all that the prophets have spoken! 26 Ought not the Christ to have suffered these things and to enter into His glory? 27 And beginning at Moses and all the Prophets, He expounded to them in all the Scriptures the things concerning Himself.
Same chapter again:
44 Then He said to them, These are the words which I spoke to you while I was still with you, that all things must be fulfilled which were written in the Law of Moses and the Prophets and the Psalms concerning Me. 45 And He opened their understanding, that they might comprehend the Scriptures. 46 Then He said to them, Thus it is written, and thus it was necessary for the Christ to suffer and to rise from the dead the third day, 47 and that repentance and remission of sins should be preached in His name to all nations, beginning at Jerusalem. 48 And you are witnesses of these things. 49 Behold, I send the Promise of My Father upon you; but tarry in the city of Jerusalem until you are endued with power from on high.
Many thanks,

Who was that written to? Paul starts out by saying my brethren. He was writing to those believers who were following the gospel as he preached it to them. What about those who preached another gospel?
But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed. Galatians 1:8-9
2 John 1:9 Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son. 10 If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed: 11 For he that biddeth him God speed is partaker of his evil deeds.
Not all who claim to be are "brethren".
