I am new to Paganism, so maybe this a very common question with an incredibly simple answer, but from my brief research I found nothing.

The numerous branches of Paganism have different beings who serve identical or very similar functions. Take thunder, for example. Celtic Pagans say that thunder’s god is Taranis. Norse Pagans believe that it’s Thor. Greek Pagans have a hunch that it’s Zeus. Roman Pagans suspect that it’s Jupiter. Slavic Pagans suggest that it’s Perun. And so on.

I am presuming that the various alternatives are never sources for heated arguments (correct me if I am wrong). So my question is, how do you reconcile a multitude of beings who all share the same job?
