Like the rest of the comments, I also would have preferred the term "Maou" to stay in Romaji.
But I don't understand the comments about that Archbishop. Maybe the religion isn't all crap, maybe the Pope is actually pretty good, but has some cleaning to do in his ranks.
Showing us the trope-y fat rapist priest is one this, but we still don't know what the Pope is like.
My biggest complaint in this chapter is the tanned Granpa. Why the hell would he be mistaken as a delinquent because of his tan?
I know Japanese people usually try to keep their skin as white as possible, but every name, city, technology and terminology in this manga is based on Medieval Europe... where being tan just means having spent a bit of time outside... or, in the south, being born.
Trying to associate him with the commoners would be OK. But a delinquent, really?
