This question came up among friends recently, and I was surprised at how hard it was for me to answer. For many years, I could come up with a goddess or god, from whatever pantheon that had caught my eye at the time, and rattle-off the many ways that I was "working with" that deity (usually in ritual, and usually for my own purposes).
Now, I worship the eldest tribe: Sun, Moon, Earth, Storm, Sea, the four Winds, Fire, Horn, and Green. They walk their own paths, and to "summon" or "devoke" Them seems odd, to say the least, if not downright delusional. If your patron goddess were Inanna, but she strolled through your town every morning, how would you "work with" her?
We hold sabbat when the Moon is full, we sing the Sun back home at Yule. When worshiping the Eldest gods, you can't answer questions like "Who are you 'working with'?" without first answering the questions "Where?" and "When?" Land and season unraveled from my gods would only leave me with personified ideas who could not move beyond the boundaries of my own belief and imagination.
The other question that I must ask is, "Who else?" The Eldest are a tribe; they are related, one to the other. At spring, the Green stretches from his Mother Earth towards the returning Sun. We live in the midst of (and because of!) these interactions. We cannot attribute our lives to just one of Them.
If the forces of nature are your pantheon, and the seasons are your mythology, then a question like "Who's your patron deity?" becomes a bit more complex.
How would you answer?
