[...], →OCLC, pages 249–250:Is the heresiarch a less pernicious member of society than the murderer? Is not the loss of one soul a greater evil than the extinction of many lives? […] If then, the heresiarch causes infinitely greater evils than the murderer, why is he not as proper an object of penal legislation as the murderer? We can give a reason,—a reason, short, simple, decisive, and consistent. We do not extenuate the evil which the heresiarch produces; but we say that it is not evil of that sort against which it is the end of government to guard.

He was illustrating an old truth, though to me then an undiscovered one, that a heresiarch may be, and often is, a very noble man, whatever may be the result to society of his views.
** 2007, Einar Thomassen (introduction), Marvin Meyer, transl. and editor, “NHC I,3; XII,2”, in The Nag Hammadi Scriptures, international edition, New York, N.Y.: HarperOne, →ISBN, page 34:Although questions remain, it is, on balance, most reasonable to assign the Gospel of Truth to the Valentinian tradition. This is also the judgment of the majority of scholars. Whether the homily was actually composed by Valentinus himself, as some believe, cannot confidently be known. However, the quality of the composition and the authority of the voice that speaks in it do point in the direction of the heresiarch himself, rather than some minor and unknown figure.

Surely the ultimate heresiarch was Peter [John] Olivi himself, and his body ("relics" to his followers, mere bones to the inquisitors) were spirited away from Narbonne at the very beginning of the conflict to be burned like a live heresiarch, with the ashes thrown into the Rhône.
