Roger Olson has offered a challenge to Calvinists in this post: A Good Analagy to the ULI of TULIP.
In answer to his question: "Which scenario better fits the biblical data, our understanding of God’s character, and our sense of justice?" . . . I'd have to say, "Neither."
The distorted Calvinistic scenario Olson borrows from William Klein reinforces my suspicion that even the most irenic Arminians really don't "get" Calvinism. Which reinforces my suspicion that real, Biblical Calvinism can only be grasped by revelation, not mere human reasoning. Fundamental to Olson's misconception is the fact that mankind did not merely put himself in a position to become spiritually dead through the fall - no, man killed himself through his transgression. Spiritual death is not something that is going to happen to sinful man; it is something that already has happened to Him. "For on the day you eat of it, you shall surely die."
Here is an alternative scenario with a more accurate Calvinism, complete with the "reversified" names:
1. The people now known as Srennis were once infinitely blessed by their Lord and Maker, Rotaerc, and enjoyed splendid fellowship with Him. For reasons no one can fathom, they decided to rebel against Him. As a result, they went insane and committed suicide, one and all alike.
2. Rotaerc loves the Srennis greatly, but He respects their freely made choice to kill themselves out of their sheer irrational hatred for Him.
4. In their peripheral vision, the Srennis can still see the carnage around them, and each one realizes he could have been - and by any just measure should have been - left dead like the others. The Hero looks upon the Srennis with deep compassion and tells them not to fear, for they are His chosen and His beloved. Each one marvels that the Hero has chosen to bring him to life, and is mystified as to why he would be the undeserving recipient of such amazing kindness. And the Hero gives the Srennis a new name: Srennis-Devas!
6. The Srennis-Devas arrive safely in Rotaerc's land and rejoice with Him forever, basking in the glorious glow of their beloved Hero and Lord - His Son Susej - and enjoying blessed fellowship with Tirips the Holy. Although they do not know why Susej left many of their brothers dead, the Srennis-Devas do not accuse Him of injustice. Rather, they fall down breathless before His goodness and enduringly trust in His pure justice and mercy.
As is the case with all analogies, this one is not perfectly accurate and has limits. However, it's a sight better, more Biblical, more fitting to the concept of justice, and more like the character of God than the ones offered in Dr. Olson's blog post. Wouldn't you say so?
