Omnipotence
"With God all things are possible"—Matthew 3:9
Catholic Dogma: God is almighty (De Fide)
If we grant the theists victory of the philosophical question "Does God exist?" we inevitably come to the question, "Does the Christian God exist?" This seems a valid question. For if the ontological proof is truly correct, then it implies that some being "which nothing greater can be conceived of" truly exists. A skeptic will ask what these "great-making" qualities are that make God the being "which nothing greater can be conceived". In answer to this, Catholic Christians posit a handful of divine properties that make God "great". The following list of properties are attributed to God by Catholic dogma:
- Omnipotent
- Omniscient
- Omni-benevolent
- Impassable
- Infinitely Just
- Infinitely Merciful
- Eternal
- Knowable by Nature
- Omni-present
- Absolutely Perfect
- Absolute Immutability
- The First Efficient Cause
If we are to answer the question, "Does the Christian God exist?" we must analyze the properties attributed to God and see if they are at least philosophically sound. In this first essay on God’s qualities I wish to consider God’s omnipotence (God’s power) and some of the difficulties with the idea of God’s omnipotence.
There are two major difficulties with an all-powerful being. The first problem has to do with the extent of God’s power. Does omnipotence allow God to redefine logic or break the laws of logic? Does God’s omnipotence mean that he is capable of sin? The second major difficulty is the apparent conflict between God’s power and his omni-benevolence. Namely, if an all-good, all-powerful God exists, why does evil exist in the world he created? These questions are real problems for Christianity, and I wish to address each of them carefully.
The reader should also be aware, that many of the problems with God’s omnipotence proceed from conflicts with his other "great-making" qualities. One possible solution to some of these conflicts is to abandon one of the properties which conflict. Another possible solution is to abandon Christianity entirely. As a devoted Catholic, I will not consider these "solutions" as valid alternatives. Indeed, I believe that most of these conflicts can be overcome or neutralized with some thought and a careful definition of the qualities of God. The definitions I will expound are Catholic definitions; in essence I will not address ad hominen arguments against non-Catholic doctrines. Instead, the following paper is a defense of the Catholic Faith from skeptics and not a general defense of the myriad of non-Catholic Christian doctrines. With this in mind I will proceed to analyze the first skeptical argument against God’s omnipotence.
Problem 1: The problem of the scope of God’s omnipotence
An Initial Definition of Omnipotence: God can do anything
The following question is often posed by skeptics of Christianity to bring about a conflict with the idea of omnipotence. The question often posed is, "Can God create a rock so heavy he can’t lift it?" This question creates a dilemma in our initial definition of omnipotence. For if God can do anything then that means he must be able to create a rock he can’t lift (even if it’s infinitely heavy). Yet, if this were true then he would not be able to lift the rock; so we must conclude that God is not omnipotent. I think the argument can be broken down in the following manner:
Def. Omnipotence means a person X can do anything.
P1. Person X can make an object heavier and heavier by way of omnipotent power.
P2. Because Person X is omnipotent, X should be able to make a rock so heavy X can’t lift it.
P3. If Person X does not have the power to lift the rock this conflicts with omnipotence
C1. Person X is not omnipotent
I think this is not a valid argument against God’s omnipotence because P2 does not make logical sense. The reason P2 is not logical, is that P2 basically says:
- Suppose a Person X exists and is purportedly omnipotent
- Omnipotent beings must be able to do A (create rocks)
- Omnipotent beings must be able to do B (lift rocks)
- X must be able to do A such that B is not possible otherwise X is not omnipotent.
Do you see the logical conflict here? Our skeptical argument asserts that God must be able to do A and B or he is not omnipotent (which makes logical sense) AND God must be able to do A in such a way that B is not possible or God is not omnipotent. The argument sets God’s omnipotence up to fail by stating that in order to be omnipotent he must be able to do three things:
- X must do A
- X must do B
- X must do A such that B is not possible [/list=1]
There is no logical way God can "do B" and "not do B" at the same time! I suppose we must conclude that there is one limit on God’s power: logic. Yet, is that really a limit? Does the skeptic truly suppose that an illogical God is more powerful than a logical God? I don’t believe so, and if the reader disagrees than re-read the above argument. The implication is that an illogical God either doesn’t exist (by the stone-lifting example) or can’t be discussed at all. For if God transcends logic, then we have absolutely no way of knowing or discussing him. Logic is the only mode by which we can make sense of the world in a rational manner. How can we even conceive of a being whose very nature is based on illogic? I submit that only a logical God is part of Catholic dogma. In fact, I will now give the reader the proper definition of omnipotence as defined by the first Vatican council:
