The mystery of Bob Thiel's Th.D may be solved, and it's a pretty strange tale.
Bob may have acquired a mail order degree from Trinity School of Apologetics & Theology in Kochi.
Following up on an anonymous tip in the previous comments section, a web search revealed that Trinity is a fundamentalist institution in India which has a Calvinist orientation, and offers "Free Apologetics/Theology Graduate Distance Programs." It's listed in places like Conservapedia and Creationwiki, and is sited next to Cochin University, but from what I can tell is definitely not part of that institution (although to read the Trinity website you might assume it was!) T of CU would then mean Trinity of Cochin University, which seems to be a clear misrepresentation.
Here's what Walston's Guide to Christian Distance Learning has to say about this institution (see graphic).
Not exactly positive.
And lo and behold, there is a Bob Thiel listed under "graduation news" on the Trinity site.
Now let's recap.
(1) If this is the source of Bob's Th.D, one can only wonder at his choice of an institution which wears its trinitarianism on its sleeve.
(2) To all intents and purposes, the accreditation that this institution claims is highly dubious.
(3) Bob has misrepresented it by calling it TCU. The correct acronym is TGSAT. The impression that he has graduated from Texas Christian is highly misleading. The impression that TGSAT is part of Cochin University is also misleading.
It appears that Bob's Th.D - if this is its source - isn't worth the paper it's printed on. No wonder Bob has been less than forthcoming about its provenance: it's a huge embarrassment.
However, on the positive side, Bob was being at least partially truthful. He does have a piece of paper with a recently minted Th.D., the quality of which is fully commensurate with the quality of his scholarship.
