Ray, I think that some people use the word ‘belief’ to mean ‘belief in supernatural reality or as ‘belief in god or gods’. Generally, I don’t think that this is a normative usage of belief but in a lot of circles it is probably pretty close.
I think that any declarative statement or sentence is a statement of belief. Now such as statement can be objective to me, “There is a huge maple tree in my yard” but it is a statement of belief to all hearers who have not seen it. Truth functional statements are always situated in an I/thou situation.
