The claim that the New Testament was originally written in Hebrew is something that must be substantiated by those who believe it with historical references, textual support, and most of all extant manuscripts in Hebrew. These references must be credible, the textual claims must be supported within a relatively conservative framework of exposition, and the manuscripts must be verified as authentic by organizations such as United Bible Societies or the American Bible Society. Thus far, no one in the Messianic community has been able to prove a written Hebrew origin for the entirety of the New Testament on the basis of these factors.
