John bar Penkaye's black book

I speak of Von Kulten, that great lost work of the mad monk... John bar Penkaye. Baumstark's footnote 4 reads: 'A[bd-Îsho] in third place. If the Kulte book exists on its own, it may carry on to schismatics within the Eastern Church herself: Bar Sauma, Hnana... edgelords like them. Unsure about that schism under Isho'yahb III; if we're lucky, we may get the Heretic of Rewardashir who (I think) was al-Khirrît. Well! such is the hope.

I have a bad feeling we shall not be lucky. I suspect we shall find these contents aussprechliche already. In part, even in English.

We already have this man's Main Points. It tells us what he cared about, and what his sources were . . . and what they weren't, starting with Epiphanius' Ephesus-associated Panarion.

We must prepare ourselves that Memre 5 and 9 of the Resh Melle be those two "volumes". Or maybe just Book 9 attached to some rando's mediaeval epitome of the Panarion.

UPDATE 2/2: The anti-sectarian work did exist. Resh Melle refers to it, so it preceded these memre. But - Mar-Emmanuel reports - it is no longer with us. But exactly because it preceded #5 and #9 (and "On The Trisagion", one assumes) - do we care?
