Hey, thanks for laying this out. If predestination is a “damnable heresy,” then the apostle Paul may want to edit a couple chapters.
Predestination didn’t start with Calvin
The word is straight out of Scripture: “He chose us in him before the foundation of the world… having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will.” (Eph 1:4–5)
“Whom he did predestinate, them he also called… justified… glorified.” (Rom 8:29–30)
So the question isn’t whether predestination is biblical, but how we understand it.
Calvin & the WCF don’t erase faith and repentance
Calvin didn’t teach, “You do nothing, don’t even believe.” He taught that
we contribute no merit - our adherence to God's law is not meritorious, but a reply to God's grace for saving us - but we really must repent and believe:
“Repent ye, and believe the gospel.” (Mark 1:15)
“Believe on the Lord Jesus Christ, and thou shalt be saved.” (Acts 16:31)
The Westminster Confession is explicit that God’s decree includes the means of salvation:
God has “appointed the elect unto glory” and has “fore-ordained all the means thereunto. Wherefore they who are elected… are effectually called unto faith in Christ by his Spirit…” (WCF 3.6)
So just like God foreordained the nail should be hammered into the plank, he also foreordained the means - the hammer would hammer the nail into the plank!
So election doesn’t replace faith; it guarantees that, in history, the elect will actually come to Christ (cf. Acts 13:48; John 6:37).
(By the way, that should be a great comfort - God has created YOU for HIS purpose, just like God created the Seraphim, whose purpose was to Praise God every hour of every day, saying "Holy Holy Holy". We too have a purpose! in fact, one day we will judge angels - so we are higher than even the angels - “Know ye not that we shall judge angels? how much more things that pertain to this life?” 1 Cor. 6:3 ) All that God does is for our Good - without knowing that, we are left with bad decisions that wreck our lives with no good reason or outcome!
Free will and God’s decree – the “how” is mysterious
Here’s the tricky part we both care about: if God foreordains all things, are our choices real? And is God responsible for sin?
The Confession answers like this: God “did… freely and unchangeably ordain whatsoever comes to pass; yet so, as thereby neither is God the author of sin, nor is violence offered to the will of the creatures…” wcf 3.1
So in classic Reformed theology:
Our choices are real, responsible, and voluntary. God’s decree is comprehensive. Yet God is not the author of sin.
How that all fits together is above my pay grade. It’s treated as a mystery- just like creation itself. I don’t know h
ow God created the world ex nihilo; I just know that He did. In the same way, Scripture shows God ordaining even sinful acts without being the sinner:
Jesus was “delivered by the determinate counsel and foreknowledge of God,” yet Peter says, “you crucified and slew” him. (Acts 2:23)
Joseph: “You meant evil against me, but God meant it for good…” Gen 50:20
So the Bible already puts God’s sovereign purpose and human responsibility side by side. Calvin and the Westminster divines are just refusing to cut off either side to make it easier on our brains.
The “twofold” decree in WCF
You quoted this rightly: “By the decree of God… some men and angels are predestinated unto everlasting life, and others fore-ordained to everlasting death.” WCF 3.3
That’s weighty stuff. But the same chapter says this doctrine must be handled very carefully and as comfort, not as a fatalistic club:
“This high mystery of predestination is to be handled with special prudence and care… so shall this doctrine afford… humility, diligence, and abundant consolation to all that sincerely obey the gospel.” WCF 3.8
So I get being wary of bad uses of “Calvinism.” But if I’m going to fight predestination itself, I have to start with Paul in Ephesians 1 and Romans 8–9, because that’s where the language and the logic come from in the first place.
In His Grip!
