That’s also a bit off topic, but interesting, and also worthy of new thread.
I think Roman Catholics have a valid gripe if they question if Tetzel was the originator of the jingle “As soon as the coin in the coffer rings, the soul out of purgatory springs” (Sobald der Pfennig im Kasten klingt, die Selle aus dem Fegfeuer springt). Sometimes Protestants think this phrase was unique to Tetzel, sort of like the way the phrase “your best life now” is attached to Joel Osteen.
A version of this phrase actually can be traced back to a much earlier date. Martin Brecht notes the University of Paris complained about this popular jingle as early as 1482 (Martin Luther, His Road to Reformation, 1483-1521, p. 183).
Heinrich Boehmer notes the idea behind this phrase wasn’t anything new when Tetzel came on the scene:
“Even the much-discussed sentences concerning the automatic effect of the indulgence for the dead- which were later compressed into the famous rhyme, ‘So soon as coin in coffer rings, the soul from purgatory springs’- were not in substance new, but merely an apt practical application of the commonly accepted doctrine, as it had been publically set forth, for example, only a few years before by Luther’s fellow-Augustinian, John Jenser of Paltz in his Coelifodina” (Road to Reformation, p. 180).
But while Tetzel may not have coined the phrase, he certainly taught it’s sentiment. Even Hartmann Grisar reluctantly admits it:
The saying about the money in the coffer cannot, indeed, be traced to Tetzel’s own lips, yet in his sermons he advocated a certain opinion held by some Schoolmen (though in no sense a doctrine of the Church), viz. that an indulgence gained for the departed was at once and infallibly applied to this or that soul for whom it was destined.(Luther 1, p. 343).
While Grisar denies Tetzel used the jingle, There is some proof that he may indeed have uttered something like it. Schaff notes,
Mathesius and Johann Hess, two contemporary witnesses, ascribe this sentence (with slight verbal modifications) to Tetzel himself. Luther mentions it in Theses 27 and 28, and in his book Wider Huns Wurst (Erl. ed. XXVL 51).
