Sorry if this is a silly question but what is it called if you believe in/worship deities from multiple pantheons (I believe all deities exist in some manner or another but mostly worship Greek and Norse ones) thank you !

daughter-of-artemis:

uhhhhhhhhhh. pantheism? multi-polytheism? your guess is as good as mine. 

i’m of the persuasion that other pantheons certainly exist, but i only worship the Greek pantheon so that’s qualified as polytheism. but… i honestly don’t know what to call worshiping more than one pantheon. followers?

The belief that all gods exist is called omnitheism- perhaps that’s closer to what you may be looking for?
