Ignoring the effect of other masses, neither body revolves around the other. They both revolve around the center of mass. In cases where one is much more massive (as with the earth and sun), the center of mass can be within the larger body.
Also, there are other bodies in our solar system that affect the motion of both the earth and the sun.
I'm not an astrophysicist or anything, and I understand your point about bodies affecting one another, but doesn't what you're saying actually illustrate that one orbits the other and it isn't a question of coordinates? From what very little I know, orbit is established by mass and so the lower-massed planets orbit the greater-massed sun while bodies of even lower mass sometimes get caught in the gravitational pull of planets and become moons.
