Westcott and Hort, who SBG has lauded on this thread, were Alexandrian Priority, yet he has said nothing negative about them that I recall, though he has attacked Dr. Maurice Robinson for being Byzantine Priority. However, the very fact that W&H called their text, based on Alexandrian mss (Aleph & B, mostly) the "neutral text," meaning it was the one most true to the originals. Does SBG say about them that "such a claim is unworkable, and cannot be taken seriously by anyone engaged in textual criticism" (from his OP)? Nope, that insult is reserved for those taking the BP position, not the Alexandrian Priority position.
Bruce Metzger is Alexandrian Priority. He wrote, "The Alexandrian text, which Westcott and Hort called the Neutral text (a question-begging title), is usually considered to be the best text and the most faithful in preserving the original" (
A Textual Commentary on the Greek NT, 2nd ed.). However, to SBG, "such a claim is unworkable, and cannot be taken seriously by anyone engaged in textual criticism." So even Metzger cannot be taken seriously by textual critics, according to SBG!!
"Reasoned eclecticism" as seen in UBS4 (I have the 4th rev. ed.) is also essentially Alexandrian in basis due to the canons of "shortest is best" and "oldest is best," though they tried not to be. So, SBG would say about their position that "such a claim is unworkable, and cannot be taken seriously by anyone engaged in textual criticism." So sorry, Barbara Aland, Kurt Aland, Johannes Kasravidopoulos, Carlo M. Martine, and again Metzger (editors of this Greek NT), none of you professional textual critics are worthy of being taken seriously!
