John Piper recently addressed how Calvinism and logic relate. His article specifically addresses how he appreciates G.K. Chesterton’s writing in spite of some significant theological differences. One of those is an appreciation of Calvinism. See the excerpts below, but then go on and read the whole article at Desiring God Blog.
What About Logic?
It is a great irony to me that Calvinists are stereotyped as logic-driven. For forty years my experience has been the opposite. The Calvinists I have known (English Puritans, Edwards, Newton, Spurgeon, Packer, Sproul) are not logic driven, but Bible-driven. It’s the challengers who bring their logic to the Bible and nullify text after text. Branches are lopped off by “logic,” not exegesis.
Who are the great enjoyers of paradox today? Who are the pastors and theologians who grab both horns of every biblical dilemma and swear to the God-Man: I will never let go of either.
Not the Calvinism-critics that I meet. They read of divine love, and say that predestination cannot be. They read of human choice and say the divine rule of all our steps cannot be. They read of human resistance, and say that irresistible grace cannot be. Who is logic-driven?
For forty years Calvinism has been, for me, a vision of life that embraces mystery more than any vision I know. It is not logic-driven. It is driven by a vision of the ineffable, galactic vastness of God’s Word.
Let’s be clear: It does not embrace contradiction. Chesterton and I both agree that true logic is the law of “Elfland.” “If the Ugly Sisters are older than Cinderella, it is (in an iron and awful sense) necessary that Cinderella is younger than the Ugly Sisters.” Neither God nor his word is self-contradictory. But paradoxes? Yes.
We happy Calvinists don’t claim to get the heavens into our heads. We try to get our heads into the heavens. We don’t claim comprehensive answers to revealed paradoxes. We believe. We try to understand. And we break out into song and poetry again and again.
From Dilemma to Unicorn
We don’t adjust the brain-baffling categories of Scripture to fit human reason. We take it as one of our jobs to create categories in human minds that never existed in those minds before “” a job only God can do “” though he makes us agents. For example, we labor to create categories of thought like these:
God rules the world of bliss and suffering and sin, right down to the roll of the dice, and the fall of a bird, and the driving of the nail into the hand of his Son; yet, even though he wills that such sin and suffering be, he does not sin, but is perfectly holy.
God governs all the steps of all people, both good and bad, at all times and in all places; yet such that all are accountable before him and will bear the just consequences of his wrath if they do not believe in Christ.
All people are dead in their trespasses and sins, and are not morally able to come to Christ because of their rebellion; yet, they are responsible to come, and will be justly punished if they don’t.
Jesus Christ is one person with two natures, divine and human, such that he upheld the world by the word of his power while living in his mother’s womb.
Sin, though committed by a finite person and in the confines of finite time is nevertheless deserving of an infinitely long punishment because it is a sin against an infinitely worthy God.
The death of the one God-Man, Jesus Christ, so displayed and glorified the righteousness of God that God is not unrighteous to declare righteous ungodly people who simply believe in Christ.
These are some of the intertwining, paradoxical branches in the tree of Calvinism. They do not grow in the soil of fallen human logic. They grow in the Bible-saturated soil of “Elfland.” Those who live there believe that a Dilemma with two horns is probably metamorphosing into a Unicorn.
I just posted this at my other site, 
I’ve been paging through a new book from Concordia Publishing House, Lutheranism 101. It’s a light-hearted yet informative look at all the ins and outs of Lutheranism. I came across a description of “the most recognized symbol for Luthernaism” — Luther’s seal. I guess this is proof positive that I don’t know much about Lutheranism since I never even knew Martin Luther had a seal.
