It makes them inferior because age doesn't mean they aren't corrupted copies. We know they are corrupted because of the missing verses, the corrections, and the overwrites.
The letter is the spirit. That's where your disconnect is. The bible is literally the word of God. If you are looking elsewhere for answers then you are being led astray. Many bible verses talk about following the original message and testing whatever spirits that try to guide you and rejecting them if they deviate.
You seem to have a misunderstanding. It isn't that I agree with or disagree with something. The facts state the King James is a superior translation. That's why I use that one. I will agree there's probably enough info to get people saved in the other versions, but they will have misunderstandings if they use them.
Abraham used a direct connection to God through the holy spirit, and wrote some of the old books (passed down to Moses who physically wrote them down).
The part you are confused on is a reference from the article that I linked. Not my words.
The vaticanus has the same issues as the Sinaiticus, both are used to make the more recent versions of the bible.
"Dean John William Burgon, personally collated the Sinaiticus and Vaticanus manuscripts. In his book, "The Revision Revised", which he wrote in 1881, he gives his opinion and
lists undeniable facts about what these two manuscripts say.
Mr. Burgon states on page 11; "Singular to relate Vaticanus and Aleph have within the last 20 years established a tyrannical ascendance over the imagination of the Critics, which can only be fitly spoken of as a blind superstition. It matters nothing that they are discovered on careful scrutiny to differ essentially, not only from ninety-nine out of a hundred of the whole body of extant MSS. besides, but even from one another. In the gospels alone B (Vaticanus) is found to omit at least 2877 words: to add 536, to substitute, 935; to transpose, 2098: to modify 1132 (in all 7578): - the corresponding figures for Aleph being 3455 omitted, 839 added, 1114 substitued, 2299 transposed, 1265 modified (in all 8972). And be it remembered that the omissions, additions, substitutions, transpositions, and modifications, are by no means the same in both. It is in fact easier to find two consecutive verses in which these two mss. differ the one from the other, than two consecutive verses in which they entirely agree.""
