"
The Codex Sinaiticus has been corrected by so many hands that it affords a most interesting and intricate problem to the palaeographer who wishes to disentangle the various stages by which it has reached its present condition...." (
Codex Sinaiticus - New Testament volume; page xvii of the introduction).
What is the writer talking about? Did you note the phrase "
to disentangle the various stages?" This indicates that there is a scribal problem with this codex and it is a BIG problem. Tischendorf identified four different scribes who were involved writing the original text. However, as many as ten scribes tampered with the codex throughout the centuries. Tischendorf said he "
counted 14,800 alterations and corrections in Sinaiticus." Alterations, more alterations, and more alterations were made, and in fact, most of them are believed to be made in the 6th and 7th centuries. "
On nearly every page of the manuscript there are corrections and revisions, done by 10 different people." Tischendorf goes on to say,
"
...the New Testament...is extremely unreliable...on many occasions 10, 20, 30, 40, words are dropped...letters, words even whole sentences are frequently written twice over, or begun and immediately canceled. That gross blunder, whereby a clause is omitted because it happens to end in the same word as the clause preceding, occurs no less than 115 times in the New Testament."
Vaticanus is the sole property of the Vatican; it has been a part of the Vatican library since at least 1475. It’s history previous is unknown. It was written by three scribes, and has been corrected by at least two more
The New Westminster Dictionary of the Bible concurs, “It should be noted, however, that there is no prominent Biblical MS. in which there occur such gross cases of misspelling, faulty grammar, and omission, as in B [Vaticanus]
Vaticanus omits Mark 16:9-20, yet there is a significant blank space here for these verses.
6 Sinaiticus also lacks these verses, but has a blank space for them.
7 These two manuscripts are the only Greek manuscripts that omit these verses!
