If a druid, cleric, or paladin character can select a god they can join their temple and so I do not list out what are default divine classes that can join a temple. So if your PC of one of those classe can select the god, it can join a temple devoted to the god and ascend into that temple's clergy.

In that player joinable faction thread for the list of temples, I only call out classes or special requirements that faction has other than the default 'divine three' (cleric, druid, paladin). However most gods don't allows paladin or druids in addition to clerics which is why in the quote from me above and in that thread you are encouraged to find out beforehand if they do. As you can probably see it's mostly for which temples allow Blackguards into the clergy (Lawful Evil deities, mostly). But there are other special situations like orc-bloods only being able to join the Orcish temple, or any class being able to ascend to the clergy in the cults of Entropy and Juiblex, and so on.
