Jon, here is an interesting refutation of Cheung. Let me know what you think:

Hey Clement,
I started on a full rebuttal of this article, but didn't have time to finish. I thought I would go ahead and post what I had, though.
I will assume the author's terminology and acronyms merely for sake of argument. In order to understand the acronyms used, you will have to read his article. In truth, I think he has oversimplified the matter, but it is not crtically important to show these distinctions as his own criticism is very much inconsistent. I have only refuted the beginning of his article, but since he first attacks Cheung's foundation and I believe I have adequately defended that foundation, none of his other arguments will follow, which means they are irrelevant.
On SS2 being incompatible with SGP.
In fact, SS2 does follow from Scripture because Scripture provides for reason through the existence of God. Christ, in particular, is revealed as the Logos, or Logic (reason, wisdom, etc.). Logic exists, and it exists within our minds through God's image. It is by logic (among other things) that we are able to learn. For instance, knowledge would be impossible if the law of noncontradiction were not true.
As reason is directly taught in Scripture (fulfills SS1) and deduction of true premises (Scriptural premises) always results in a true conclusion, it follows that what is deductively derived from Scripture is true.
This is consistent with the SGP.
On SS2 being incompatible with SGP, part 2
The author correctly observes the use of inference and the assumption of inductive practice by the authors of the Bible, especially the New Testament. What the author fails to realize is that it is only the expression of the underlying concepts that is inductive and not the concepts themselves. For instance, we would never argue that God "might" be love (induction, at best, only gives us a probability). The concepts that Scripture points to are unequivocally true.
The objection then comes, how do we know that we have made the correct deduction? How do we know that when the Scripture says "God is love" that is really doesn't mean "God is powerful"? To this we reply that it is transcendentally true. It is mere wishful thinking and argument from ignorance to say that even though the Bible says one thing it is possible that it means something else.
Another objection is that we do not have proof that Scripture is deducible. To that we reply quite the contrary! This too is transcedentally true. For instance, only Calvinist soteriology fits into a consistent biblical worldview. Arminianism is inconsistent and illogical. So while, on the surface it might appear that we could inductively reason Arminianism from the texts, this is deductively an invalid soteriology. As God is completely logical and rational, we should strive to make our understanding of the text parallel this directly. As our Lord says, "Be perfect as your Father in heaven is perfect." If God is perfect and logical, then it follows that we should strive to be perfectly logical with our evaluation of the texts.

The author argues that Cheung's epsitemology is circular because it assumes that deduction is a valid proof for the principle that something can be validly deduced from Scripture. The author says that it assumes deduction is valid before it proves that deduction can be valid.
Now, this at best is just skepticism. Logic and deduction are necessary truths. When we speak of worldviews and rationalistic systems, we must assume that logic and deduction are valid ways to arrive at truth before we can even begin to establish these systems. The Scripture tells us why logic is necessarily true: because it reflects the thinking of God. Because God is logical he made everything logically, thus the only way to arrive at precise conclusions is to use logic.
If the author wishes to argue against logic, then he is free to do so and appear quite looney at the same time.
His objection here is simply invalid. Everything must first assume logic, which is precisely what the presuppositional worldview explains.
Can SGP be reconciled with SEP?
Here, the author really trips over himself. Little does he know, but he denies God's omniscience with his argument, which is:
"That is, the idea that all propositions not contained in or implied by Scripture cannot constitute knowledge, is itself either contained in or implied by Scripture (where implied by means validly deducible, of course). . . . SEP isnt a proposition of Scripture."
The Scriptural propositions that God is omnipotent and omniscient form the basis for SEP. I think the author has missed this point. Something is a true proposition if God knows it. What God knows he has willed through his omnipotence. God does not know anything that he has not willed. This would be a logical contradiction.
The Scriptural premise of SEP is therefore simply, "Only what God has willed is known by God and therefore knowable." This is the basis for Cheung's Occasionalism, which is attacked later and I will address later. Because the full rebuttal of this point relies on this reference to Occasionalism, I won't be able to complete it here.
Neverthesless, the author does try to refute this point with Scripture, but fails miserably. He cites Mt. 24:32, "Now learn the parable from the fig tree: when its branch has already become tender and puts forth its leaves, you know that summer is near." In the first, this argument is out of context because he is ignoring Cheung's Occasionalism which explains how this knowledge is possible. In the second, this is a parable for the second coming of Christ. It is not a literal saying, but a figurative one.
He then goes onto Acts 2:22, but this is explained by Occasionalism as well, along with any other circumstance in which knowledge is imparted to men by "occasion" of sensation.
The author clearly fails to understand that what is deduced from Scripture is not necessarily all true propositions, but the basis for all true propositions. Scripturalism does not say 2 and 2 are 4. Scripturalism does say
how 2 and 2 are 4, though. Likewise is it so with sensation and other principles.
What Cheung defines is a biblical worldview, not an exhaustive copendium of every true proposition possible.
When I first came across Cheung I was somewhat enamored with his work. My head has since cleared and I now view it on a reasonable plane, but that does not mean that I no longer agree with it. In fact, I still agree with
most of what Cheung presents,
especially his Occasionalism and rejection of empiricism. What I disagree most with Cheung is his harsh and abrasive attitude in dealing with unbelievers.
Yes, they are stupid and irrational in the grand scheme of things, but I reject the notion that bringing up such things is in anyway helpful, except perhaps for encouraging aspiring apologetists to not fear them.
In any case, I agree with much of what he writes, but take issue, in many cases, with how he rights it.
Soli Deo Gloria
