Yes, I do think that. I guess I don't really know why you would exclusively worship only one or two deities when they're part of a pantheon. By honoring gods in a pantheon at all I think that says you are polytheistic in the first place, so why practice monotheistically.
I don't know, I'm still sort of "feeling things out" in various areas. If you are called by a deity/deities, you would specifically honor them. See, to me polytheism vs. monotheism is more about the
belief than the practice. IE, I believe they all exist, I just worship Q, X, and T, and sometimes F. Or I only worship J but believe in G-M. And so-forth.
Also, what if you are called by deities from different pantheons? And here I will begin to derail my own thread, haha! But I guess then you wouldn't be following a specific pantheon. ... idk, just thinking out loud here.
