a priest is specifically an officiant. I don't think the background should necessarily carry that baggage. An acolyte, by contrast, is merely a temple-worker. I think the latter noun encompasses the meaning of the former without proscribing religious callings other than the pulpit.
I do understand your position, I just don't agree with it, and the rhetorical colouring of "merely" points to your presuppositions. "Priest" carries different baggage than "acolyte", but neither are problem-free. I note that you combine "officiant" with "the pulpit", which is pretty religion-specific.
Priest is definitely a more recognizable word, but it is more recognizable because it carries unintended meaning. Players will see "Priest" and ignore the description, thinking, "I know what a priest is," and picturing a man in a white robe holding a chalice aloft while chanting in an ancient language.
This at least overlaps with the trait that you get when choosing the background, and so this is a good association...
Players are more likely to read the description of an "Acolyte," even if they have a fundamental sense of what an acolyte is, which gives the background more breadth. Breadth is good.
...rather than no association.
I agree that breadth is good. I believe I am arguing for a broader use of backgrounds than you are. The use of "acolyte" (whether as temple functionary (as you present it) or generic religious person (as presented above)) is limiting.
I suggest the societal function of "priest" (which I can take to be any religious functionary, in a term everyone will understand) should be divorced from the character class of Cleric.
I disagree, and think you're underestimating the vocabulary of gamers. In addition, if some don't know the word, there's nothing wrong with giving them a new term that (if they just read the background) is perfectly clear.
I'm not saying that gamers don't know the word. I am saying its a word that (in its normal sense) only makes sense if priests exist somehow. I'm also saying it's a word 95% of gamers would not use in a context independent of their games.
The thing about 'priest' is that it is inclusive of both the village-guy-who-marries-you AND the cleric. It's a bigger term than the more specific ones (members of the cleric class and village-guy-who-marries-you).
And this is exactly the step backward I am talking about. The huge benefit that the backgrounds introduced -- the thing that I am reluctant to lose -- is the separation of these two things: now the guy-who-marries-you doesn't have to be a cleric.
That is the breadth that the backgrounds introduced -- this association was no longer the default. It could still exist (did all of the cleric pregens have priest as their background? they might have), but the system allowed for other possibilities.
