I recently read Plato’s Apology (that is, Plato’s account of Socrates’ defense against accusations of “impiety” and “corrupting the youth of Athens”), and I was fascinated by the use of swears (e.g. “by Zeus!”) and the way they referred to their gods. If they didn’t name a specific god, it was always “a god” or “the god” or “the gods” or even “the gods of the city”. There was always a sense that they were referring to a specific god or set of gods.
This is in contrast to the way that modern Christians refer to their god. They never use his name. It’s always an indirect reference, like “God” or “the Lord” (often with His pronouns capitalized), where they refer to their god by title and act as if that title is their god’s name.
The language use itself asserts their position that there is exactly one god, and it is their god. This is a social convention that I delight in going against, by always being specific about what god or sort of god I am talking about (e.g. “the Christian god” or “any gods”). I refuse to tacitly let the assumption that there is exactly one god slide by using language which implies this is so.
Besides, one thing I’ve noticed about referring to one’s god as “God” is that it becomes very easy to assume that any conversation about a god concept is about one’s own god. For instance, in any philosophical argument about the existence of some manner of creator god, people often see this as being about their “God”, whether or not any connection is made between the philosophical creator god and their god.
Honestly, it irks me that most Christians don’t refer to their god by a name (unless they’re specifically talking about Jesus). I know it’s taboo for them to say their god’s name, but using the generic god concept word in the place of their god’s name is not the only way to handle this. And yes, I know this isn’t the fault of individual Christians. It’s just the social convention we are all used to and which is seldom questioned. But it sucks. And it wasn’t until I was reading a philosophical work referencing the Christian god (as opposed to the Athenian gods), and started to question why I felt more comfortable mentally replacing “God” with a specific qualifier (e.g. “the Christian god”), that I even started to notice any of this stuff.
