I have noticed that you tend to be focused on the "letter" of the scriptures. You focus on mislabelings and contradictions to the letter. I don't believe Satan corrupts the word of God by changing the letter. He is more clever than that. What Satan does is IMO more insidious and clever. He manipulates the Spirit of the scripture.
"He has made us competent as ministers of a new covenant--not of the letter but of the Spirit; for the letter kills, but the Spirit gives life." 2 Corinthians 3:6
I can conlcude with this verse that if Satan's goal was to cause spiritual death, changing the letter of the scriptures will not work. He has to manipulate the meaning or context of the scripture. Much like polititians use sound bites to manipulate the context of an opponents statement to make voters believe something that isnt true.
We have seen two examples where Satan would use the word of God and twist it's context to deceive. The first example is the temptation of eve. Satan quoted God yet he manipulated the context to deceive her. Because she was ignorant, she fell to that temptation. The second example is Jesus being tempted by Satan in the wilderness. Again, Satan used scripture in a twisted context to deceive. However, since Jesus also knew the scriptures, was able to see right through that deception and resist the temptation. Myself and many other Christians have learned from these examples that one of the ways to defend against this deception is to try to understand the scripture in its appropriate context so that it may be understood correctly. This is where the study of hermeneutics comes into play. It is also important to understand OT hebrew and NT Greek.
Not only Satan can twist and distort scripture to deceive, but people do it also. These are false prophets and false teachers. You yourself have used clips of scripture to distort it's context to deceive. I prefer to think you do it unkowingly. Just as eve fell into temptation out due to ignorance of the spirit, you too have been deceived because of your insistence on the letter without understanding the spirit of the Word.
It sounds like you are saying that premise 3 is false, and you use two references to back it up.
But why would Satan prefer to have the truth plainly visible to all humans and then try to distort it rather than simply obscuring the truth entirely so that no one can possibly know? There is no way the father of lies would prefer to have the truth plainly visible to all.
You're making Satan out to be a movie villain, like he puts James Bond in a death trap and then just leaves, or maybe he builds a death star with an extremely vulnerable area fully exposed that, if shot, will trigger a chain reaction to destroy the whole star. Reality does not function like this. When you have an objective, you don't toy with it. You crush it.
So if Satan desires to alter the Bible, but doesn't, then he is not able to. Yet humans are able to, despite being far less powerful or intelligent. I asked for a sensible explanation, and you have not given one.
Furthermore, you are not addressing obvious objections to your own points:
1. When "Satan" (the serpent) was talking to Eve, he actually did alter God's words. Therefore your first example is factually wrong. He did not quote God and then twist the context; he completely misquoted God on purpose.
2. When Satan was talking to Jesus, he couldn't have deceived Jesus since Jesus is omniscient. In addition, this has nothing to do with the written word being corrupted. This is different than the situation with Eve because now there was a physical hard copy of God's word, so orally twisting the words won't do anything. Therefore this point of yours is entirely irrelevant to the discussion.
3. Even if you have established that Satan twists scriptures, that does not establish that he has no desire to alter them outright. If his methods are deception, he will use all tools at his disposal.
Now you may ask, "If Satan had succeeded in altering the scriptures, why does Jesus not remark on this in their conversation?" The Bible seems to claim that it is inerrant (Psalms 12:6-7, Matthew 5:18) and the idea that scriptures could be corrupted does not seem to exist even as a peripheral thought in the Bible. For this reason, the existence of transcriber errors themselves should be sufficient to destroy one's trust in the Bible. Regardless, if these transcriber errors did not exist in Jesus' time, but then propagated later, there's no reason to believe that Satan could not have altered the texts to his liking while the transcriber errors were propagating.
In conclusion, your rejection of premise 3 is unfounded, your first example is completely erroneous, and your second example is irrelevant.
