I followed a link this mp3 file: http://www.trinitylectures.org/MP3/AubAveTheo_Collection13.MP3 , a critique of Auburn Avenue theology and theologians. I found some of what the speaker had to say excellent, and some of speech wanting. His most glaring error is to equate human logic, speech, precision of mind at this point in history with same from before the Fall, or at least pre-Babel-Tower. Failure of that magnitude by one who avows belief in the inerrancy of scripture is a significant lapse and bespeaks an agenda, a rubric elevated above truth claims in support of those truth claims.
The other place the speaker falls short is in his critique of another theologian (both speaker and names of his opponents have now gone from my memory, for the most part) who stated in effect: Extrapolating principles from the writings of the Pauline and other NT epistles, then rearranging those principles in systematic forms – confessions, for instance – tends to alter the meaning the biblical writers intended to convey. C’mon, although reasonable minds can differ on that one, I think that statement, identified by the speaker in this audio file as heresy, is clearly arguable and non-heretical.
Essentially the Trinity Foundation guy argues that post-canaonical, therefore non-inspired, human codification of biblical teaching and principles is unquestionably right, after having argued that human logic, communication, speech inerrantly derives from that of God. I’m not buying it.
