Facts not Faith
For (at least) as far back as the 12th century, it has been commonly accepted that there are 'limitations' even with an omnipotent deity (and a bit later; "Nothing which implies contradiction falls under the omnipotence of God." -Aquinas).
Simply put, omnipotence is 'the ability to do anything that is possible to do'. To ask that one 'do something that isn't possible', is to ask that someone 'do something that isn't anything'. For those that wish to redefine it to suit their argument's needs, it simply isn't valid.
The rock 'argument' is no more than a play on words, which when distilled into an equation, shows itself to be illogical on its face. The language used develops a paradox inherent in the words themselves, not in this god's supposed attributes or abilities.
It is a cousin of the 'can god create a square-circle' problem, which suffers from the same type of internal logic problems. With both, you are essentially asking if god can make 'A' = 'not A'. Can (he) actualize a logical contradiction. The answer (no) has nothing to do with this god's 'abilities' or 'power'.
It is worthy of discussion in that it raises the question of whether or not this deity would be 'subject' (subordinate?) to the laws of logic. Most theologians worth their salt seem to think that god does operate within logic, but that this does not somehow lessen (his) abilities. I've no idea how that's supposed to work. But this is a different, more direct, and in my opinion more fruitful question.
(Incidentally, I'm a dyed in the wool atheist. I just happen to have a low tolerance for poor arguments, despite which 'side of the aisle' they come from.)
I think the rock argument disproves the omnipotent in its strictest form (can do all things) but it does disprove the bible's conception of the omnipotent. Maybe a few bible verses can clear this up.
I got the definition of omnipotent from thefreedictionary.com below.
om·nip·o·tent (m-np-tnt)
adj.
Having unlimited or universal power, authority, or force; all-powerful. See Usage Note at infinite.
n.
1. One having unlimited power or authority: the bureaucratic omnipotents.
This definition of omnipotent does not contain the stipulation that you can do everything ...but... the logically impossible.
Here is revelations 19:6.
Then I heard what sounded like a great multitude, like the roar of rushing waters and like loud peals of thunder, shouting: "Hallelujah! For our Lord God Almighty reigns.
This is the new international version. The King James Version uses the word omnipotent rather than almightly. Here is the definition of almightly.
al·might·y (ôl-mt)
adj.
1. Having absolute power; all-powerful: almighty God.
Here is the definition of all-powerful.
all-powerful
adj
possessing supreme power; omnipotent
These definitions do not place a limit on the omnipotent. It seems like the omnipotent can do absolutely anything regardless of whether it is logical or not.
The bible gets more specific about what it means by omnipotent.
Here is Matthew 19:25-26
25 When the disciples heard this, they were greatly astonished and asked, Who then can be saved?
26 Jesus looked at them and said, With man this is impossible, but with God all things are possible.
Here the bible becomes very specific about what it is defining omnipotence to be. According to the bible when you are omnipotent you can do all things. Again this conflicts with your stipulation that the logically impossible is beyond the omnipotent.
These three bible verses below specifically says that God can do everything and that there is nothing impossible.
Job 42:2
I know that thou canst do everything, and that no thought can be withholden from thee.
Jeremiah 32:17,27
Ah Lord God! behold, thou hast made the heaven and the earth by thy great power and stretched out arm, and there is nothing too hard for thee:
Behold, I am the Lord, the God of all flesh: is there any thing too hard for me?
Luke 1:37
For with God nothing shall be impossible.
