Neither philosophies (such as the Green Faith or the Whispering Way) nor pantheons can have clerics in Golarion. See here.
Fair enough; What about other non-traditional deities? Why does a clearly defined divine source of power have to have a name and a face for a cleric to be able to worship and gain spells from it?To clarify a point; When I say 'follows the Green Faith' I meant more than just living by that philosophy. I meant that the cleric would worship, venerate, and pray to nature itself in the same way another cleric might do to, say, Torag.
Also, the other half of my question remains. Why not?
It just makes no sense to me that a cleric could not gain spells from worshiping something another class can worship and gain spells from.
The way I see it, there are two options;
1.) Classes are an abstraction of the game's mechanics, and have no actual bearing on the in-game setting. In which case, which of the rule sets of the various classes I pick to represent a character should be based entirely on which mechanics best reflect that character. If so, then the Golarian setting should allow for people to play clerics that worship non-traditional deities, even if the title they go by in the game isn't 'cleric.'
2.) What a character's class is is actually relevant to the in-game setting, from a narrative stand point. In which case, the rules for clerics in Golarion make no sense at all. A character who calls themselves a druid, and worships the sun, is completely acceptable; worshiping the sun can grant you divine magic. However, if that same character declared that they were a "Cleric" of the sun... well, then there divine magic just stops working. Why? Because James Jacobs doesn't like clerics that worship the sun. Because it's easier to say, "No, clerics can only get magic from it if it has a name and a face," than "clerics can gain divine magic by worshiping anything that qualifies as a source of divine magic. The sources of divine magic in Golarion are..." and then just highlight that Razmir isn't one.
