You say that other theologians (such as Geerhardus Vos, whom you quoted) have said essentially the same thing I do. So, if you accept what he says, and presumably, then, what I said in similar terms as they, why do you consider [supralapsarianism]? Is it not humanly ordering God's decrees?
First, you are being inconsistent, which makes it difficult to track your meaning. On the one hand you speak of God's one "decree," but on the other hand you speak of God's "decrees." You switch from singular to plural and back again. Vos said two things that mirror statements you have made and with which I agree: (1) "There are in God not many decrees, but it is one, single, completely present decree." (2) The "differing parts of God's decree" are not temporally ordered, as that would be "incompatible with his eternity."
Second, it is a logical ordering of God's decree, not a human ordering—unless you presuppose that logic is a human invention, a premise that I would strongly oppose (but is beyond the scope of this thread).
That being said, how are these two points made by Vos supposed to complicate my acceptance of a supralapsarian view?
I don't see how God's decrees can be ordered logically.
God's decree is ordered logically by the necessity of the case. For example, the eternal intratrinitarian plan of redemption (x) presupposes something from which to redeem and someone in need of redemption (y). In other words, x is unintelligible apart from y—or, in philosophical terms, y is the necessary precondition of x.
Yet both x and y are simultaneous constituents of God's one eternal decree. When Reformed theology speaks of the logical ordering of God's decree, it does not mean that God deliberated sequentially. Rather, it refers to relations of logical priority within a single, eternal act of divine willing. The decree is one, simple, indivisible act in God. There is no process, no composition, no succession of thoughts in him.
"Indivisible? But are we not dividing it here?"
We do not divide God's decree in itself. We acknowledge that to us, as finite beings bound by discursive reasoning, the decree must be considered in its constituent relations if we are to speak of it at all. This distinction is standard in Reformed theology: The decree
in se (as it is in God) is simple and indivisible, but the decree
quoad nos (as revealed to us and contemplated by us) can be distinguished in its logical relations and dependencies.
So, we speak of a "logical order" not because God’s decree is composed of parts, but because human understanding requires us to contemplate ordered relations of purpose within that singular divine act.
Think of it this way: God wills the end together with the means, and the end is what grounds the means or makes sense of them. Nothing yet has happened sequentially, so there is no temporal priority. This is strictly a logical priority, where x does not make sense without reference to y—that is, y is the ground or reason of x. His decree is not a web of disconnected choices but a unified, purposeful plan that centers on Christ. And Reformed theology affirms this because scripture reveals a God who acts with intentionality, not randomly or arbitrarily (Isa. 46:10; Rom. 9:22–23; Eph. 1:11).
The cross of Christ was not an afterthought or a reaction to sin; Christ is the Lamb slain from the foundation of the world, which shows that sin was ordained for the sake of displaying the glory of the crucified and risen Son—a supralapsarian insight for you, there.
It is almost as though lapsarians are saying that the one THING follows another logically (I have no problem with that), but then they call the THING, "decree".
I don't think they do. Vos certainly did not, for example. He called each of the things "differing parts" of God's one eternal decree.
Let me approach it like this —Are we capable of logically ordering God's thinking?
I don't accept the premise of your question. It is not as if we are inventing and imposing a structure onto God's eternal mind. That would be the height of presumption. But Reformed theology maintains that God himself has revealed his decree in such a way that it reflects purposeful relationships—means (e.g., election) serving ends (e.g., redemption), and all centered on the glory of Christ.
This logical ordering is not a human construct imposed on God from below; it is a divine disclosure accommodated to our finite understanding. Scripture itself gives us categories of purpose, subordination, fulfillment, and so forth. For example, when Paul says in Romans 9:22–23 that God has endured with much patience the objects of wrath prepared for destruction in order to make known the wealth of his glory on the objects of mercy he prepared beforehand for glory (Rom. 9:22-23), that is a revealed ordering of purpose.
So, we are not ordering God's thinking. We are receiving the structure of God's eternal decree as God himself has chosen to make it known. We are not trying to map God's inner life from the outside; we are thinking God's thoughts after him in the way he has revealed them to us.
