We like to say in Hellenic and Roman religions that we're orthopraxic and beliefs don't matter. And certainly, unlike most modern religions, we don't have a long list of rules and beliefs mandated by a religious authority.
Nonetheless, there was a widespread belief in ancient times about how religion worked. There was seemingly a default theology.
We call this _do ut des_ . I give so that you may give. Embedded in this concept are some default assumptions:
*The gods exist on some level
* The gods have the power to intervene in human life on some level
* The gods are essentially benevolent and act as supernatural benefactors when properly propitiated
* The key to propitiating the gods is through proper ritual
* Proper ritual involves a votive gift to the gods
It's a system of exchange whereby we gift the gods through votive offerings. In return, it is thought, they confer their blessings on us.
I therefore take exception to the idea that belief is irrelevant. The above is the central core of Greek and Roman Polytheism. People acting outside that theology are not acting within the scope of historical Greek and Roman Polytheism.
For instance, there are people whose "theology" is essentially politics. There are people on both the right and left who have a carefully crafted version of paganism that reinforces their political agenda. Their religion is ultimately about them, not about the gods.
There are people whose religion is essentially about self help or therapy. The gods are only needed to the extent they supposedly teach life's important lessons or provide emotional comfort and a sense of support. In some ways this seems to be the default assumption of more New Age approaches. This approach to religion seems less about the gods and more about emotional needs.
I can have reasonable disagreements with people and not think they're bad people or that they're doing it wrong. But this assumes we're all operating within the universe of a traditional theology of _do ut des_. People operating outside that theology seem to be in a different religion. And it's hard to have a conversation with them because we're speaking essentially a different language.
And they have every right to act and believe as they want: but the question is can we comfortably share the same space in what is supposed to be a Hellenic or Roman pagan forum? On that, I say no. And that's why I say this "belief doesn't matter because we're Orthopraxic" mantra is overstated and perhaps we should stop saying it.
