Why, then, is the name absent from the extant manuscripts of the Christian Greek Scriptures or so-called New Testament? Evidently because by the time those extant copies were made (from the third century C.E. onward) the original text of the writings of the apostles and disciples had been altered. Thus later copyists undoubtedly replaced the divine name in Tetragrammaton form with Kyʹri·os and The·osʹ. (PICTURE, Vol. 1, p. 324) This is precisely what the facts show was done in later copies of the Septuagint translation of the Hebrew Scriptures.

The so-called Christians, then, who “replaced the Tetragrammaton by kyrios” in the Septuagint copies, were not the early disciples of Jesus. They were persons of later centuries, when the foretold apostasy was well developed and had corrupted the purity of Christian teachings.​—2Th 2:3; 1Ti 4:1.
