So much for documenting the claim, now ducking out with a haughty "this is afar as I'm willing to go with it".
As far as "rivers in Egypt" go, what of the denial concerning the presumption of singular office of papacy?
There was no such thing from the beginnings of the church.
And just the other day...the bishop of Rome made noises towards re-affirming (within the RCC) acceptance homosexuals as priests -- as long as they did not engage in the act itself.
They could even become bishops & cardinals too? Are there a few there already? There is, isn't there? Does that drive you batty? It would me, if I was the sort to be demanding strict celibacy while at the same time going the extreme as to equate even masturbation with the sin of Sodom.
While you're at it, go back to the chart and push back the Reformation a full century or so.
Hus pointed out the errancy of singular papacy. That really burned them up. They really burned Hus up. Cooked his goose as it were, but were unable to, as Hus prophesied, trap, catch, or roast a singing swan who would come a hundred years later (as documented by Poggius the Papist).
Hus also mentioned how that of seven sacraments, all seven were available to none. Priests not allowed to marry, and those whom were married, not allowed the sacrament of priesthood. Such was not the case for "the church" in it's first centuries.
At one point Hus also asked if "the church" was composed only of the priesthood. In the context in which that arose, it was an honest question.
Who is "the church"?
If Hus and Jerome could have been more carefully listened to, tolerated ---perhaps have been allowed to bring correction to the political/religious entanglements & intrigues (if not out-right den of iniquity>/a>) the RCC had become --- then much of the violence associated with the Reformation could have been avoided.
