Martin Luther (on St. Thomas Aquinas), ignoramus

In the whole of Thomas [there] is not one word capable of facilitating trust in Christ.

"Im gantzen Thoma ist nicht ein wort, das einem mocht ein zuuersicht zu Christo machen."

     Martin Luther, Tischrede 1721, 12 (?) July 1532, WA-TR 2, 193, ll. 5 ff.  I'm not seeing it in the American edition ed. Pelikan.  Paul M. Bretscher ("Neothomism," Concordia theological monthly 21, no. 4 (April 1950):  258n11) translates this more professionally than I as follows:

In all of Thomas there is not one word which might arouse in one confidence in Christ.

     I was put onto this by the Lutheran (?) theologian Stefan Gradl.  See his "Inspektor Columbo irrt:  kriminalistische Überlegungen zur Frage 'Kannte Luther Thomas?,'" Luther 77, no. 2 (2006):  91 (83-99).  "Inspector Columbo" is, following Otto Pesch, Denis R. Janz, whose Luther on Thomas Aquinas:  the Angelic Doctor in the thought of the reformer (1989) is said to have converted even Pesch himself to the view that Luther knew Thomas well.  Having traced the history of the debate, Gradl goes on to argue 1) that Janz was quite mistaken (that, barring the discovery of sources hitherto unsuspected, Luther very likely did not know Thomas well), and 2) that, anyway, the question is not only unanswerable (???), but entirely beside the point, dogmatically speaking.
