There are four different "text types" for the Greek New Testament. Some refer to them as "families". There are no two Greek texts identical in every detail even within such "families". No matter what Greek text one claims to believe to be the most faithful to the originals, it will have to be an eclectic blend of a number of Greek documents. God has miraculously preserved 5500 copies of these Greek documents (found thus far; their probably are more) for which we should all be thankful.
