Many changes have been made to the Bible over the centuries. The last chapters of Mark wre added later, for example.
It's not the large scale mix-mastering that some seem to believe. In the NT there are only 3 of any significance. The "woman caught in adultery", the few extra verses at the end of Mark, and the "comma johannium".
There is a good bit more than that — starting with the fact that the Bible was written in Greek, but Jesus spoke Aramaic, meaning that his words were already translated when transcribed, and many words in Aramaic have multiple meanings. How are the original scribes (and/or those who were telling the stories orally before they were transcribed) sure they got the right one?
But that’s just the first problem. There are whole sections added and deleted from the early versions that we hve, as well as what appear to be transcription errors that potentially could change the meaning of a passage.
(What if I hand-wrote “change” but you transcribed it as “charge”? A whole different meaning.)
