Just to be clear, I'm giving all people who say they believe in God the benefit of the doubt, but a theistic God probably at its most essential point requires that there is no other logical or physical possibility. If I'm wrong about that, then there is a stronger definition of God out there and some might say, per the ontological argument, a God such that no other explanation is possible is a greater God than a God such that it could have been otherwise.
I think that's enough to let me know what you mean.
I have to admit that I find logical necessity a slippery concept. I keep wanting to say that it could just be a fact that God is necessary. I know that this is missing the point of necessary existence but it's a point I find easy to miss.
To me theism means believing in an ultimate being, for a worthwhile value of "ultimate". Given what existence actually is (whatever it actually is), it's a fact that without God nothing at all would exist. But does this have to mean that God is logically necessary, in the sense that no other explanation for any part of reality could even be self-consistent? Maybe I'm just dim on this point, but I simply don't see it.
Anselm's ontological argument is a fun little exercise but I've always felt that Kant killed it. You can't define things into existing, or I'd fill my wallet with the greatest conceivable dollars. I think the problems are with the concept of logical necessity, not with the concept of God.
If you want to identify theism with belief in a logically necessary God, then okay; I can try to cook up some other term for the kind of thing I believe. I don't really think would be a fair or reasonable terminology, though. I think it would be like defining physics to be the concepts of Newton. Logical necessity and the ontological argument are medieval theology. They were cutting-edge ideas in their day, but we've come a ways since, at least in logic if not in theology.
