That is no longer
natural theology, but is
sacred theology. If you refer to sacred theology alone, you are correct in asserting that human reason unaided can not grasp it (refer to the list of anathemas I posted, which includes this very proposition). But, you become confused, when you believe that
anything relating to God - including natural theology, which is based on human reason alone: it is human philosophy pondering God - is impotent except for divine revelation, which it is not. These truths (about God, not including things like original sin) can be known without one iota of divine revelation.
God exists.
God created everything.
God is necessarily one, and only one, God.
God is eternal.
God is impassable.
God is the first cause.
God is pure act.
God is the unmoved mover (or “unchanging changer”, in modern terminology).
God is omniscient.
God is non-corporeal.
(Which fall under the heading) God is perfect in all ways.
These truths can not be known by human reason alone, but require divine revelation:
God has revealed himself to humans.
God has issued divine revelations. (This assertion requires divine revelation to assert.)
God cares about mankind and is involved in their affairs.
God is three persons in one God, a Trinity, a hyperpersonal being.
One Person of God became incarnate, and pitched his tabernacle amongst us men as one of us.
God, in human flesh, died on the cross.
God, in human flesh, died for our sins. (How? is another question for sacred theology.)
Another Person of God, the Holy Spirit, indwells all believers.
Believers are the mystical body of Christ.
God established an infallible Church to teach his truth and maintain divine revelation.
If God is omnipotent, it seems God can choose to go out of existence since God can do anything. Thus, God can go out of being. If God cannot choose to go out of being, God cannot do anything. Thus, God is not omnipotent.
This is incorrect, and belies your lack of understanding here and now, although I do appreciate that you seem to be willing to learn to understand. Simply: if God could go out of being, he would then have no actuality (or, “the potentiality of no actuality”, both a contradiction, and an unrealized potential: if God could cease to exist, the ceasing to exist would be a potential that is not actualized, so God would not be pure act). If God can choose to go out of being, God is not God, as God can not be anything but pure act.
I may go through the effort to lay it down in a series of syllogisms. Even the tract is lacking proper syllogistic format. It is much harder to write and express in syllogisms, and takes much more time, but terms are much more easily defined and fallacious reasoning is much more easily uncovered, and generally has a name, such as
“denying the antecedent”, “affirming the consequent”, “excluded middle”, etc. If you wish, you should familiarize yourself with the basic form of term logic (as elucidated in Aristotle’s Organon and distilled in many textbooks and across the internet), and logical fallacies (or improper applications of term logic, which nullify the essence of logic, “when starting from correct premises, a correct conclusion follows”).
PS I know it’s confusing, but “act” and “actuality” are synonyms, as are “potential” and “potency”. I use both, incorrectly, some times (the traditional terms are act and potency, which I have found confuse many people).
