I recorded and posted yesterday Word Magazine # 27: Rejoinder: James White and 2 Peter 3:10.
Jeff Riddle claimed that the NA28 has readings in its text that have zero extant Greek manuscript support. You reply here by saying:
"1) the cj's are never put in the text."
That is simply incorrect. Readings with no Greek manuscript support are adopted by NA28 in Acts 16:12 and in Second Peter 3:10.
