The god and gods tags seem to be a little unnecessary. At the very least, they are redundant with respect to each other. Also, as has been discussed here I'm not even sure if these words make any sense to use on our site.
Simply put, the tags are synonyms, and on top of that, they're very ambiguous.
It might also be helpful to have a tag to refer to the supreme deity, but since everyone interprets the identity and name of that diety differently, I'm frankly not sure what we would call it.
