First of all, I don’t think the rude comments above are representative for how most players think about this. It’s just people on the internet being people on the internet - which is sad, but that’s how it is.
Maybe Zentais comments pushed the discussion more in the direction of what place religion should or should not have in a video game. Which wasn’t really where the “where is the church?” question was coming from, I think. So there it was him overthinking, probably.
I don’t think any religious person (or anyone else for that matter) could be offended by the lack (or existence) of churches in a game. I mean it’s not like everyone was such a devout christian in the first place! 
(We’re talking about players placing a church building and the faith need meter goes to green - from what I hear that’s not a super accurate representation of christianity anyway lol.)
Like I said, you’re giving us a specific setting that evokes certain expectations (no matter your intentions) - that’s why for many there’s churches simply missing.
Your bridges comment is funny nonetheless, but looking at this like it was a debate about religion probably doesn’t help, because I don’t think that’s what this is. It’s about player expectations and individual associations with the medieval era.
