Is the definition of God consistent?
As many of you, I've come across a few paradoxes of all sorts, from logic to math, linguistics and so forth. Some of such involve God or, at least, what Western Philosophy attributes to it.
As an example, assume God is omnipotent, he can do everything he wants to. May he be able to destroy himself? If he is omnipotent he can. However, God cannot be eliminated by definition. Thus, there is a kind of (possibly linguistic?) contradiction.
Furthermore, will is God really capable of doing miracles? Well, suppose he can do things that violate the laws of Nature. I say I can always define a new law of Nature, which is the set of laws we know, plus the fact that God can, occasionally, violate those laws. This is a new law that even God won't escape.
So my question is simply this: are these just linguistic issues? If so, how can we even think of reasoning about such issues, if language itself lacks of such description capabilities?
