From Middle English patriark, patriarche, from Late Latin patriarcha; later reinforced by Old French patriarche, from Byzantine Greek πατριάρχης (patriárkhēs, “the founder of the tribe/family”), from Ancient Greek πατριά (patriá, “generation, ancestry, descent, tribe, family”) + -ᾰ́ρχης (-árkhēs, “-arch”), with some senses likely influenced directly by Latin pāter (“father”) or Ancient Greek πᾰτήρ (patḗr, “father”). Compare matriarch. Surface analysis patri- + -arch.
Tho the similarities between patria and pater are certainly not accidental.
So bottom line, patriarch is less gender specific than pope.
... so there's even more gender-bias than I had noticed !!
Has it actually been ascertained that if the Vatican was to appoint a female Pope in the future that she could not be referred to as "the pope" ?
I'm guessing that the notion of a female Pope is so unthinkable to the Vatican (and its adherents), that her actual title has not yet been considered.
> subsequent popes were subjected to an examination whereby, having sat on a so-called sedia stercoraria or "dung chair" containing a hole, a cardinal had to reach up and establish that the new pope had testicles, before announcing "Duos habet et bene pendentes" ("He has two, and they dangle nicely").
