Welcome to Gaia! ::

As a race, as a species, we're pretty fickle little blighters. I think the Gods aren't so much understanding but tolerating. I highly doubt They make any investment in us without expecting a return in the short or long run.

I imagine that the best bonds, relationships and rewards come when one has settled with their chosen pantheon permanently. When a bond has been made with the Gods anyone would be a fool to break it. But They know us. They know of our uncertainty, and caution. Our inability to commit without investigation.
I imagine They expect this behaviour of us. I doubt They'd want us to make ties with Them and then spend the rest of our lives thinking "s**t, I wish I'd gone with the other pantheon."

I also think its as much Them trying us on for size as it is for us trying Them on. They need to know we're reliable, honest and committed before They take us on.

It's an open culture so I don't see why you couldn't smile

With the way some places have become nowadays, like America is just one giant melting pot, of different heritages and cultures mixed together. I would think that the gods would at least tolerate it if not expect it.
The Romans and Egyptians mixed together somewhat and some believe the Egyptians and Celts did as well. It just has gone on throughout time. So I would think that it is okay. Especially if you keep them seperate, just be careful of not taking on too much at one time.

Which is why I taken a break between books and topics. Like I'll read something on Norse religions and deities. I'll do other reading then go to another path (like Greek or egyptian) ad I repeate the process. I keep seperate notebooks and journals.

Yeah. I tried to do the same thing once. Now I am working on the Gods that have come to reveal themselves to me through my sabbats practiced.
