In the comments of the previous post, a reader asked this question: Can someone please explain to me how you can use the TNIV for in-depth study? I love the TNIV, but I am having a hard time using it for deep study because of the dynamic equivalence. I don't know if this is a mindset or an actual problem.
Well, I don't think it's an actual problem (for which I'll make a case below). However, if it's mindset, it may come from using formal equivalent translations for so long. I know because I've been there. Some days I'm still there, but I've made lots of progress!
Really, it may be difficult to answer your question definitively because (1) I don't know what you were using before the TNIV, and (2) I don't exactly have a definition for what you mean by in-depth or deep study. Nevertheless, I'll make some assumptions and answer the best I can.
First, let me make a clarification at the very beginning. In my reading of the TNIV, I don't consider it a pure dynamic equivalent translation at all. I consider it a median translation, sometimes more literal and sometimes more dynamic according to the decisions of the translators (and all translation requires such decisions, even interpretive decisions). On one side of the spectrum, one can find fairly literal translations such as the NASB or the NKJV. On the other end, one can find good examples of dynamic equivalency in translations such as the GNT and the CEV.
In the middle are translations such as the NIV/TNIV and the HCSB. The NRSV is a bit closer to that median range than was the RSV, and the NLT2 is not quite as far down the road of dynamic equivalency as was the NLT1.
You might even want to check out an old post of mine, "TNIV More Literal than the NASB?" where I point out renderings where the TNIV is more literal. It's so not throughout, but the TNIV is more literal in some places meaning these categories are not always hard and fast. And I've also demonstrated a number of times that the TNIV is much more formal/literal in its renderings than the NIV.
As for doing in-depth study, let me point to the example of the NIV. The reality is that there are more commentaries and reference books in the modern period based on the NIV than any other translation, and as I've pointed out, it's more dynamic than the TNIV is!
Granted most of your more "in-depth" commentaries will deal directly with the original languages, sometimes offering the writer's own translation (WBC) and sometimes not (ICC). But a number of mid-level commentaries will use the NIV and still interact with the original languages to a certain extent. The NAC is an example of that. The body of the commentary itself is based on the NIV, but the writers are free to interact with Greek and Hebrew in the footnotes, allowing the reader to go more in-depth as he or she wants to based on knowledge and ability. I might also point to the Cornerstone Biblical Commentary, another mid-level series, and this based on the NLT2 (much further along the dynamic path than the TNIV) which is an attempt to facilitate serious study using a non-formal/literal translation.
Another reason for the success of the original NIV for serious study was the early development of the Goodrick-Kohlenberger numbering system which connected the translation back to the original Greek and Hebrew. If you've ever spent any time with it, you know that the GK system is more than simply the NIV version of Strong's dictionaries. It not only fixed Strong's but improved it since the GK system takes the connections of homonyms and related words into account in its system. The development of the GK numbering system for the NIV allowed access to the underlying Greek and Hebrew of the translation to anyone whether they had studied original languages or not. This gave access to significant technical works such as the NIDOTTE to all, even if the user hadn't studied Hebrew.
So, what about the TNIV? Well, keep in mind that it's a new translation. But I do know that a project is well underway to apply the GK system to the TNIV. Once that is done, the reader can have instant access to numerous reference works tied directly to the TNIV, even taking advantage of those older works written in relation to the NIV. Plus we'll be able to have tagged electronic editions of the TNIV in computer software. Currently, I still use the NASB as my default translation in Accordance because it's tagged, but I'll gladly switch the default to a tagged TNIV when it becomes available. [Note: I don't use an original language text for my default in Accordance because I prefer to have the software open to a text containing both testaments].
Also the forthcoming second edition of the Readers Greek New Testament is going to reflect the Greek text of the TNIV, a welcome update to the current edition.
All of this to say, I believe the TNIV is set quite well for serious study. So, is it a mindset issue, after all? Well, maybe. There's still a popular notion that literal = more accurate, and that
simply is not true. I've tried to demonstrate this a number of times, too. I would especially recommend two blog posts I wrote a while back:
Challenge of Bible Translation edited by Scorgie, Strauss, and Voth.
Finally, while it's good to have a primary translation (I'm working very hard to make the TNIV mine), truly in-depth/deep study is going to require reading multiple translations in parallel. Since I usually pursue any significant study of the Bible in front of Accordance these days, I have a "first tier" of sorts that I have open before me as I study. This includes either the Greek or Hebrew and then my preferred English translations: NASB, TNIV, HCSB, and NLT2. The original languages plus a variety of translation approaches help me to study and understand the passage better. I also have a second tier that I examine if I have time including the ESV, NRSV, JPS (which sometimes moves to the first tier on OT passages), NET, KJV and others.
I hope I've helped to answer the question. Further questions and your comments are welcome and encouraged.
