Both admirers and enemies of codices Vaticanus and Sinaiticus readily admit that these two codices are remarkably similar, so similar as to compel one to believe that they were of common origin. Dr. Gregory, a recent scholar in the field of manuscripts, believes that the Vatican and Sinai manuscripts are 2 of Constantine’s 50 bibles. He states, “This Manuscript (Vaticanus) is supposed, as we have seen, to have come from the same place as the Sinaitic Manuscript. I have said that these two show connections with each other, and that they would suit very well as a pair of the fifty manuscripts written at Caesarea for Constantine the Great” (Dr. Gregory, The Canon and Text of the NT, p. 345). Also, in his Introduction to Textual Criticism of the NT, Dr. A.T. Robertson states, “Constantine himself ordered fifty Greek Bibles from Eusebius, Bishop of Caesarea, for the churches of Constantinople. It is quite possible that Aleph (Sinai) and B (Vatican) are two of these fifty.”
