Calvin said God's will is a perfect unity, or "one", and the distinction between hidden and revealed will is not true, it only falsely "appears" to be true because human beings are afflicted with the limitation intellectual feebleness:
If Calvin was correct that the divine will is "one and undivided", then I'm forced to conclude that the distinction between decretive and preceptive will, that you allege to be true about god, is
not true about god.
The premise to a syllogism must assert
actual truth...not merely truth
as wrongfully perceived by "feeble intellect...". Otherwise, yes, the syllogism is doomed be either invalid or unsound.
Thus the singular descriptive word "will" in P1 did not constitute the ambiguity or imprecision you thought it did. It was in perfect accord with what you and Calvin think is the
actual truth about god's will. A will that is "one and undivided" is truthfully represented with the unqualified expression "will".
That is, when P1 says "The elect should do anything God
wills them to do", you are wrong to complain that "will" doesn't specify which particular aspect, decretive or preceptive. Logic and truth are not served if they are based on what Calvin said were false perspectives arising from "feebleness of intellect..."
But anyway, I'll modify the syllogism to please the Calvinist critics, who seem to be perfectly certain that which particular "will" of God is meant here, makes significant difference:
- Premise 1: An elect sinner should do anything God has secretly willed them to do.
- Premise 2: God secretly wills for the elect sinner to sin.
- Conclusion: The elect should commit sin.
So if we forget the prior lesson which taught that the syllogism is doomed when it proceeds upon any premise that is actually false (like the premise that the difference between God's decretive and preceptive wills is not mere appearance, but actual truth), well, you can't dispute P1 because you believe it "true" that God has a secret will respecting an elect person.
You cannot dispute P2 because you are Calvinists. See WCF sec.3.
NOW tell me why the conclusion is false.
