You are ignoring the fact that Greek manuscripts differ and either none of them are correct or only one of them is correct. If you believe none of them are correct and they all must be compared to arrive at whatever you think it closest to the original, then you are making yourself more authoritative than the written Word of God because you are denying that the Word of God is written and given to us without error.
"The New Testament is constantly under attack, and its reliability and accuracy are often contested by critics. If the critics want to disregard the New Testament, then they must also disregard other ancient writings by Plato, Aristotle, and Homer. This is because the New Testament documents are better-preserved and more numerous than any other ancient writings. Because they are so numerous, they can be cross checked for accuracy . . . and they are very consistent.There are presently 5,686 Greek manuscripts in existence today for the New Testament.1 If we were to compare the number of New Testament manuscripts to other ancient writings, we find that the New Testament manuscripts far outweigh the others in quantity."
"As you can see, there are thousands more New Testament Greek manuscripts than any other ancient writing. The internal consistency of the New Testament documents is about 99.5% textually pure. That is an amazing accuracy. In addition, there are over 19,000 copies in the Syriac, Latin, Coptic, and Aramaic languages. The total supporting New Testament manuscript base is over 24,000.
Almost all biblical scholars agree that the New Testament documents were all written before the close of the First Century. If Jesus was crucified in A.D. 30., then that means the entire New Testament was completed within 70 years. This is important because it means there were plenty of people around when the New Testament documents were penned--people who could have contested the writings. In other words, those who wrote the documents knew that if they were inaccurate, plenty of people would have pointed it out. But, we have absolutely no ancient documents contemporary with the First Century that contest the New Testament texts.
Furthermore, another important aspect of this discussion is the fact that we have a fragment of the gospel of John that dates back to around 29 years from the original writing (John Rylands Papyri A.D. 125). This is extremely close to the original writing date. This is simply unheard of in any other ancient writing, and it demonstrates that the Gospel of John is a First Century document."

Besides, if all the original manuscripts are different, then we are all in BIG trouble. God preserved his Word, in the Greek for the New Testament, and through the Masorites, in Hebrew, and through the Septuagint the Old Testament in Greek.
Not a big believer in inerrancy, but certainly in inspiration. God has inspired the Bible, it teaches us the truth, and points us to Jesus.
