Torah TrueTM

There is an interesting footnote in Haym Soloveitchik's (seemingly) famous article Rupture and Reconstruction: The Transformation of Contemporary Orthodoxy Tradition, Vol. 28, No. 4 (Summer 1994).

...“Torah-true.”...86

86 This was a creative mistranslation of the German "Thoratreu" (faithful to the Torah), used by the neo-Orthodoxy of Germany. It was first used by modern Orthodoxy but subsequently attained far greater currency among, what is called, right-wing (though not haredi) Orthodoxy. See Jenna W. Joselit, New York's Jewish Jews: The Orthodox Community in the Interwar Years (Bloomington: Indiana University Press, 1990), p. 4.

I know the latter point (that it "was first used by modern Orthodoxy," e.g., it is a ubiquitous phrase found in the writings from the 1930s by rabbis like Leo Jung). What I did not know what its origin in German neo-Orthodoxy, "thoratreu." I guess I always assumed it stemmed from the expression תורת אמת. Of course, it might have anyway.
