Well, in terms of the very definition of logic, it only deals in the realm of correct/incorrect, true/false given a certain premise/statement. So, multiple conclusions can only be reached if the premise allows for multiple conclusions. At the pinpoint of the argument regarding god, I cannot see multiple conclusions at the very basic level other than, either it is or isn't. Now, what 'god' is/can do, be, sing, can very well have premises that are not contingent on dichotomy with one another, hence, leading to multiple conclusions. But, the very basic question of belief, and, using the definition of what logic is....it's either right or wrong given a premise. Hence, my argument that you cannot use classical logic to base it on.
