Can a character take a deities divine fighting style that is not proficient in the weapon that it uses?

[Mysterious Stranger]

Is there any reason a character who is not proficient with a deities favored weapon cannot take their divine fighting style? Specifically, I am looking at taking Sarenrae’s Mercy on a solar bloodline sorcerer. While being able to ignore the penalty for dealing nonlethal damage with a scimitar is useless to a character not using a scimitar, the ability to deal nonlethal damage with any spell with the fire, good o light descriptor is well worth the feat.

RAW, if the weapon is not a requirement for the feat then no.

but i can see a lot of GM who would scorn taking it without knowing how to handle the weapon the style is supposed to work with.

Sarenrae Divine Fighting Technique isn't a "weapon style", it is a "Fighting Technique". It works with both scimitars and spells with the fire, good o light descriptor. Barring someone from taking it "because he doesn't know how to use scimitars" is like barring someone from taking Piranha Strike "because he doesn't know how to use a short sword".

If I would GM like, "What, my party wants to interact with my carefully crafted NPCs in way that maybe dont kill them? YESSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS"

Seriously, I changed non lethal damage to "you dont do crits" rather then "-4 to AB". Houserule I would frankly recommend.
