In Holy Tradition of Orthodoxy it is known the life of the saint Mary the Egyptian (+522), which is an example of repentence, overwhelming for the human nature. From very young age she left her parents. Far from home, she spent 17 years into lechery. One day happened a miracle in her life and she realized how sinfull she was. Very ashamed in front of the God, she felt so much guilt. Counting on the help of the Virgin Mother of God, she left the world and she went deep in the desert spending there 47 years in very wild places, without to see any human face, without food and loosing her few clothes in a short while. Her surviving there was a miracle. One year before to die, God sent abba Zosima, a monk, to find this treasure hidden deep in the desert. When he met Saint Mary, he implored her to tell about all her life from early ages until the last day. Abba Zosima was very impressed, crying all the time when he heard her story, but in the same he was amazed about the fact that she cited words of Scripture, knowing in the same time that she never learnt from the books and she never heard anyone who sang or read these words.
Saint Mary told to abba Zosima:
The word of God are alive and active, by itself teaches a man knowledge.
The saint John Chrysostom, in Homilies on Matthew, explains that God gave us His word, not using ink and paper, He writes directly in human hearts with Holy Spirit. God didn't gave writtings to Noah, to Abraham, to his offspring, to Job, to Moses. Instead of writtings, He gave to the apostles, the Holy Spirit saying:
(John 14:26) He will teach you all things, and bring to your remembrance all that I said to you.
(Jeremiah 31:33) I will put My law within them and on their heart I will write it; and I will be their God, and they shall be My people.
(2 Corinthians 3:2-3) You are our letter, written in our hearts, known and read by all men; being manifested that you are a letter of Christ, cared for by us, written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts
And saint John Chrysostom, concludes in Homily 1 on Matthew:
But, since we have utterly put away from us this grace, come, let us at any rate embrace the second best course: the written Scriptures.
In his Homilies, saint John Chrysostom tell that even in his times, 347-407, the Scriptures had many enemies trying to change them, to cut them or to destroy them completely:
Matthew 28:12-15 And when they had assembled with the elders and consulted together, they gave a large sum of money to the soldiers, and said, “You are to say, ‘His disciples came by night and stole Him away while we were asleep.’ “And if this should come to the governor’s ears, we will win him over and keep you out of trouble.” And they took the money and did as they had been instructed; and this story was widely spread among the Jews, and is to this day.
It is known that Orthodoxy is a very "conservative religion" with everything old and everything hard to be understood by our modern minds. But its Holy Tradition, is not tradition made by men, is the way to keep everything revelated from the the God, in its original form as much as possible, unaltered, unreformed, uninfluenced by the temporary teachings of humanity. It is made only by saints, to remain Holy. And the Scriptures are part of this Holy Tradition.
Even if some texts of the Bible were altered by "academic" translations, re-writtings, the good news is the word of God cannot be changed, or losed definitively, because the finger of God will write His word every time in humble hurts looking for Him.
