Okay, after some informative discussion with a Ph.D. friend of mine, I have a few points to offer, since, first, it's hard to believe that someone of the caliber and character of Logsdon would openly lie on such an issue, and second, the Lockman Foundation's carefully worded statement in regard to Logsdon is quite strange unless there was something to his claims that they wished to alleviate.
So the most likely scenario is the following:
1. Logsdon was clearly a close friend of Dewey Lockman.
2. When Lockman devoted his fortune to fund the NASV project, he likely asked his minister friend Logsdon for advice on how to get it going.
3. Logsdon helped: (a) with his suggestions on updating the 1901 ASV which eventually became the NASV's preface, parts of which may retain Logsdon's original wording; (b) with recommending Hebrew and Greek experts for the translation team; (c) with initial interviewing of possible translators, particularly those in and around the Chicago/Wheaton/Moody area where Logsdon resided, since Lockman was in California and not an expert anyway.
4. Logsdon only worked with Dewey Lockman at this preliminary stage, and was never part of the actual Lockman Foundation nor NASV translation or editorial team (thus the explanation for the somewhat peculiar wording of the Lockman Foundation's statement on this point).
5. However, Logsdon almost certainly was involved with the beginning stages of the NASV that led to the creation of the Lockman Foundation and the later translational work of that organization.
6. At some point Logsdon was propagandized by KJV Only or Textus Receptus Only advocates, accepted their claims, and then openly renounced his previous support of Lockman's project, the NASV.
So are there any objections to this synthesis of the historical data?
