So i did the quest. I have no idea if this is an endorsement of John Hus or a condemnation of it lol. I even got a "sinner" achievement for it but i think all in all Vavra probably actually thinks Godwin is a good character, instead of being the decadent degenerate he actually is and a living condemantion of everything Hus is said to have taught in this game. The irony of course is that John Hus taught nothing of the like and he would have loathed Father Godwin to the core. And yes, he would also argue that Father Godwin would most likely go to hell, and would deplore the idea of leading people into accepting that kind of degeneracy as Henry does at the end of the sermon.
I'm going to have to say it but i despise this kind of amorality, that its ok to be a degenerate as long as one is "honest" about it. I guess as the argument goes, we are all sinners and degenerates, and there's no such thing as being free of vices and desires, so anybody who pretends otherwise is ipso facto an hypocrite and a liar, and those who openly indulge in their depravity are the "good" people because they are just being honest about what humanity is.
The funny thing is that the portrayal of priests having concubines in the middle ages is done through a modern lens. The characterization of Godwin is done through the view point of someone who thinks a priest having a concubine must invariably imply he is some kind of libertine. In reality concubines were not something akin to "sex slaves" but were surrogate wives. Concubinage can actually be traced back to Roman times, where marriage carried all sorts of heavy social and legal repercussions, and men often resorted to concubines when the committment to marriage was still not possible. St Augustine was heart broken when he had to severe ties to his concubine after his mother arranged a marriage for him with another woman, which shows that his concubine was basically just a wife to him in all but name. It's likely that between the time the celibacy of the clergy was first enrforced and the time the crack down begun to have an effect some priests carried with concubines as if they would when they still had wives, which means their relationship to them was just as discreet as that of any other married couple, or more closely to that of any married Orthodox priest.
Like a lot of things in the Church, the question of the celibacy of the clergy took a long time to establish itself as a universal rule, and along the way there were many debates and disagreements. The Gregorian point of view won with the Second Lateral Council, but even after that there were still disagrements and the rule wasn't followed or enforced everywhere. For that, it had to wait for the Council of Trent. Hence, while it was possible to find a priest with a woman and even children in the middle ages, its a bit absurd to think they just used them as any common prostitute.
