If the future is known, without any doubt, then we live in a deterministic universe, and there is no free will.
I have given you ample reasons to demonstrate the defect in this line of thinking.
God's foreknowledge of your choices does not make these choices any less free. The only way your choices are not free is if some external influence coerces you otherwise.
Are you trying to say the future is forseeable, but not determined?
It is foreseeable, not determined. There are also numerous examples of a non-deterministic reality -- the uncertainty principle and the whole of quantum field theory, to be exact.
In which case, there is no omnipotence,
Again, I have already stated the solution for the omnipotence paradox in my argument with lagboltz.
The paradox is based on the vacuous truth of a null proposition (god can create a rock he cannot lift). And what you are forgetting about the properties of a null set is that no set conditions and all set conditions apply. That particular property of the null set is an axiom of set theory hence applicable to first-order predicate logic.
So you see, there is no need to qualify absolute and limited omnipotence. God can create a rock he cannot lift and then proceeds to lift it anyway.
The same argument against the omnipotence paradox applies.
but an option that does allow theorizing a limited, but compassionate God. Which is where Dr Who goes, and an option that is not self-contradictory.
This bears on epistemology, particularly, the nature of fallacy.
Granted that the human mind can conjure a fallacious argument, does fallacy have an objective existence?
Like the null set, a fallacy, at best, has a vacuous truth. Personally, I think it has no objective existence.
