KalebOutWest : If you are referring to the Codex Sinaiticus, this is an answer.
Thank you for your comments. However, while you say a lot about codex Sinaiticus you do not answer the question as to why scribe A (or the scribe of his exemplar) altered Revelation 3:14 if he did not understand it to mean that Jesus was God's first creation.
KalebOutWest : It is also not the standard reading that was being circulated at that time,
It was clearly the standard reading at the time and place that the copying took place. But whether or not it was the standard reading, the question remains as to why a scribe altered the text if he did not understand it to mean that Jesus was God's first creation.
KalebOutWest : By the time the Codex found its way to the Monastery of Saint Catherine, because of the fact that the readings were considered non-canonical and the fact that the collection contained non-canonical books not accepted by Christianity, someone that did not realize what the collection could mean to history tossed it aside to be burned with the rubbish.
The account of part of the manuscript being burned as rubbish comes from Constantin Tischendorf when he discovered the manuscript at the monastery in the nineteenth century. What amazing timing, that after caring for the manuscript for 1400 years Tischendorf should just happen to be there when they were going to burn it. That account is denied by the monastery and not taken seriously by scholars. It just made Tischendorf look like a hero and justified his theft of the manuscripts. Your suggestion that it was related to non-canonical books is without foundation and, frankly, absurd.
