Gerhard Forde describes Lutheranism as a sort of materialist religion, not in the Weberian sense but in the actual experience of Christianity. God doesn't add up all your sins and good deeds to calculate if you've gained an entry ticket to heaven. Nor is he merely an example which you should follow as an inspiration and try to emulate, because he was the best guy to ever live. He calls this ladder theology, the idea that if we do enough of the right things, we transcend to heaven.
Forde contrasts ladder theology with Martin Luther's theology of the cross. We are creatures, he says, living beings created by God, rather than a holding tank for the soul. God wants us to embrace our creatureliness, but as creatures, we can't know God beyond what has been revealed to us in our own world: the death and resurrection of Jesus, represented by the sacrament (baptism, Eucharist, and the Word).
We live in God's creation, and we should admire it, but it is nevertheless not the same as the sacrament. He’s not going to show up in a beautiful vista, no matter how hard you squint at it—like one of those Magic Eye pictures.
The logical consequence of Luther's theology is predestination. If you need to experience God directly to be saved, and you don’t convert or have the good fortune to be born into a Lutheran family in northern Minnesota—or wherever else they reside—you won’t receive the sacrament. But how do you know if you're *really* receiving the sacrament? This doctrine, as we all know, fills the believer with the same horror and fear that Luther sought to escape.
It seems to me that the doctrine of predestination turns God into a liar. A Christian would retort that of course I'd make that claim, because I'm not a believer. Fair point.
Finally, Forde speaks of demons but never really clarifies what he means. He argues that—though none of us will know for certain—perhaps evil is God's way of showing good, i.e. Jesus. If this is true, then the sacrament would need to be expanded to include blood and horror.
