Staffan said:Yes. Whether he'd be able to cast any cleric spells afterward is a different issue (and up to the DM).
I assume you mean that while the spell was active you wouldn’t be able to contact / receive spells from your god. If this is the way your DM rules it, it makes the Protection from (X) spell MUCH more powerful.
If you fight an evil cleric, cast Prot Evil on him, boom he’s not a cleric anymore. He can’t even dispel it because he can’t cast anything.
