For instance, I've read this:
This was a reply to my remark that the setting of the adventure (Scourge of the Demon Wolf) seemed essentially atheistic. And this post reinforces that impression quite strongly. First, there's the notion that the bailiff is "the final authority except on matters of religion" - in mediaeval life there is no such distinct category as "matters of religion". One can try and contrast temporal and church government, but that is also contested to say the least (see eg the investiture controversy). Second, the summary includes this: "Meeting the Elder First: One of two likely encounters that could occur when the characters enter the village, involves going to the church first and meeting the Elder (Priest) of Mitra, Goddess of Honor and Justice." In a context in which there are murders taking place, and dead bodies of tinkers lying around, and bandits in their camp, where are the people doing penance, parading around their village bare foot repenting their sins and praying for relief, etc. More generally, where is the sense of a non-material outlook on things?
