In one sense I fully agree. Higher criticism assumes a naturalistic approach to Biblical doctrine, and much modern textual criticism also assumes a naturalistic approach. As a matter of interest it is worth listening to the debate on Eph 3:9 between James White [JW] and Jeff Riddle [JR]. When JW tried to argue one uses a scholarly textual criticism to determine the text of ancient writers such as Plato, JR correctly argued that the Bible is not a naturalistic book - it is a supernatural book. That said I think the argument is a bit more nuanced. The KJV has a number of text notes that suggest certain phrases or verses are not part of scripture. See for example the KJV notes at Luke 10:22, 17:36 and Acts 25:6. The KJV also appears to question parts of 1 John 2:23. Modern translations (including the NKJV) do not question this. I have previously mentioned Beza's textual emendation at Rev 16:5. My point is - do the KJV translators engage in some naturalistic textual criticism and doubt some passages of scripture with these changes/ footnotes? Someone like JW is quick to capitalise on these KJV textual issues.
See my comments above.
Coming back to the Eph 3:9 debate between JW and JR. I think JR was right to point out JW naturalistic assumptions. However JW pointed out that the slim textual evidence for the KJV reading of Eph 3:9 ignores the fact that God works through history. JW also pointed out that JR was inconsistent in that he defended the reading of the last few verses of Mark 16 by appealing to the
majority of mss, but defended the KJV reading of Eph 3:9 by appealing to the
minority of mss. It seems to me JW is correct on this point. That said I think JR was right to say that JW defence of the CT has produced a textual criticism that is uncertain and changing, based on the latest fads of modern textual scholars.
This argument certainly has some appeal for me. Perhaps the best Reformed TR scholar who argued for this position is Edward Hills. It is interesting that James Price's book "King James Onlyism" ch 12 summarises Dr Hills argument and accuses him of circular reasoning.
https://www.jamesdprice.com/images/King_James_Onlyism.pdf Maybe he is right. But is it not true that Presuppositional Apologetics has pointed out that all reasoning is circular by its nature. We presuppose the self-attesting nature of scripture based on the infallible authority of God who gave us the scriptures.
In the final analysis I am back to my original argument. It may be good to have a new edition of the TR but in the few places where it is problematic, it would be wise to revise it by the weightier mss of the Byzantine tradition.
It is worth listening to the JW and JR debate.
