Advocates of the Byzantine textform position such as Dr. Maurice Robinson do not "count mss" and do not use the majority methods of Hodges and Farstad, or Wilbur Pickering.
Please clarify. In your very long quote I only see four.
And how is Wallace more knowledgeable than "famed textual critic" Metzger, who I quoted as saying four Greek endings?
I have quoted Metzger contra your understanding of Wallace. And while I respect Wallace's worldwide pursuit of new Greek mss, and his Greek expertise (I've taught from his textbook), in textual criticism he is not in the class of Metzger, who (though I disagree with him) is one of the editors of the UBS text, and author of authoritative books on textual criticism.
I'll wait for you to specifically give from your Wallace quote the "more than four" Greek endings, because I don't see it.
