Thomas A. Fudge, Jan Hus: religious reform and social revolution in Bohemia (London: I. B. Tauris, 2010), 143, citing "De decimis, in Historia et monumenta, vol. 1, p. 159." This would be Historia et Monumenta Joannis 2 v. (Nuremberg 1558). Assuming that the pagination is the same, that would be here in the 1715 printing in Google Books (though I have not read and translated anything more than the most obvious paragraph in the Latin):
The Latin of Hus is closely related to that of Wyclif.
Jus Canonicum vocatur Jus a Prælato vel Prælatis institutum & promulgatum, ad rebelles sacris regulis coercendum. Et potest etiam intelligi, ut communicans juri Evangelico, ut sunt articuli fidei, in sanctis Synodis sive consiliis explanati. Sicut enim idem est homo in vestibus aut accidentibus notitiam inducentibus varians, sic eadem est lex vel veritas Evangelica in Evangelio implicita vel detecta, & per Ecclesiam postmodum aliter, sed non contrarie explanata, ut patet de fide, quam credimus.
Canon law is [(vocatur)] law instituted and promulgated by a prelate or prelates for coercing rebels by holy rules. And it can even be understood as participating in the Evangelical law [(communicans juri Evangelico)], as do [(sunt)] the articles of faith articulated clearly by [(in . . . explanati)] holy synods or councils. For just as a man [who] varies in the garments or [other] incidentals [he has] put on [(vestibus aut accidentibus . . . inducentibus)] is known to be the same, so the law or Evangelical truth implicit or uncovered in the Evangelium, and by the Church afterwards otherwise but in no contradictory manner explained, is [known to be] the same, so that it is revealed to be 'of the faith' we believe [(de fide, quam credimus)].
Neander had translated this somewhat more loosely as follows:
Das kanonische Recht wird das von den Prälaten bestimmte Recht genannt, welches dazu dienen sollte, die den heiligen Gesetzen der Kirche Widerstreitenden in Schranken zu halten. Und es kann verglichen werden mit dem evangelischen Recht, wie die Glaubensartikel, die von den heiligen Synoden sind bestimmt worden. So wie der Mensch derselbe ist, wenn er auch in verschiednen Kleidern und under anderen, wechselnden, zufälligen Merkmalen erscheint, so ist es dasselbe Gesetz oder dieselbe evangelische Wahrheit, wenn sie in dem Evangelium implicite enthalten ist oder entfaltet, und nachher durch die Kirche auf andre, aber keine widersprechende Weise erklärt worden.
This Torrey rendered in the following manner:
Law, as determined by the prelates, is styled canonical law; and its purpose is to restrain, within due limits, whatever stands in conflict with the holy laws of the church. It may be compared with the evangelical law, the latter being the articles of faith which have been determined by the holy synods. As the man remains the same, though he may appear in a different dress, and under different, changeable and accidental characters, so it is the same law or the same evangelical truth which is contained implicitly, or unfolded in the gospel, and is afterwards expounded by the church in another but not contradictory manner.
"whatever conflicted with the church and revealed truth", whether "outright doctrinal deviance" or "contumacy": One was as good as the other; either was more than sufficient for a heresy conviction under prevailing canonical legislation and custom" (Fudge, Jan Hus, 144, in summary of the discussion on 140-141).
By "the church and revealed truth" Hus would undoubtedly have meant only something like the church insofar as conformed to revealed truth as impressed (somehow) upon the conscience ("since men like Hus already held the a priori assumption that secular and religious authority might be invalid if these powers existed in conflict with what Hus considered principles of the law of God" (131)). Fudge's response: this was precisely the problem. "After all, few heretics ever imagined they were truly heretical" (137).
Still, the claim of conscience returns with the rest of the sentence: "and it is nearly impossible to impute error to oneself when one is convinced, as Hus clearly was, their focus is truth" (137, italics mine).
Yet if Fudge (who follows Kybal) is to be believed, there remains the curious stand (or "psychological dependence") on St. Augustine. For "In the final rejection of the submission formula Hus declared that he feared accepting it on the grounds that it would be to go against Augustine" (133, citing "De Vooght, p. 445", italics mine).As for "the function of canon law," "Hus did accept force in matters of faith, at least theoretically, but certainly not to the extent of death" (144 and 286n4, where the Contra octo doctores, in Opera omnia, vol. 2, pp. 464-465 is cited; cf. the introduction to Jan Hus at the Council of Constance, ed. and trans. Matthew Spinka (New York: Columbia University Press, 1965), p. 63):
I concede therefore that manifest heretics should be subjected to force by the church, that they may truly confess Christ and his law, for while no one may believe apart from his own free will, one may be forced to physical acts which then may induce one to believe.That as quoted in Thomas A. Fudge, "'Infoelix Hus: the rehabilitation of a medieval heretic," Fides et historia 30:1 (Winter-Spring 1998): 72 (57-73).
