Theological Discernment strips away the accretions of pious personality and religious pomposity to expose the core of a preacher's or a theologian's message. If that core isn't Christ and him crucified... If that core doesn't seek to take everything captive to Christ, then that preacher or theologian is not a "theologian of the cross" but rather practicing theologies of glory.
Theological Discernment is about having the tools to strip away such accretions. Steve Paulson--professor of systematic theology at Luther Seminary in St. Paul--recently delivered such a set of tools into my hands. The tool set consists of three questions that can be posed to a preacher's sermon or a theologian's writings. If the preacher or theologian have answers that differ from the ones given, then it's likely they don't have their Christology right. If their Christology's not right, they're not properly distinguishing Law and Gospel. If they can't distinguish Law and Gospel properly, then they're operating under the "opinio legis" system and not from "fides Christe."
Steve's three questions followed by their appropriate answers are:
1) Who or What killed Jesus?
Answer: The Law killed Jesus because he was forgiving sins.
2) What did God do with a dead Jesus?
Answer: He raised him from the dead so that he would continue to forgive sins.
3) Where do you find Jesus now?
Answer: On the lips of a preacher who's declaring your sins forgiven.
My take:
Simple.
Religion--because it operates under the "opinio legis" always seeks to complicate things and to introduce extraneous matters. There is "complex" religion and "simple" religion. In complex religion there are a multitude of persons all arranged in a hierarchy of authority, all demanding obedience of one kind or another; your religious "duty" is to determine your place in the hierarchy and be appropriately obedient. In simple religion the complexity has been reduced to two persons: Jesus and you; your religious duty is express your loyalty to your "pal" Jesus by not disappointing his or others expectations of your relationship.
Faith--because it is the operation of "fides Christe"--simplifies everything: It is Christ and Christ alone. Jesus Christ lays no burden of religious duty on you--he carries your burden. Jesus Christ requires no piety from you--whatever piety you practice is for your own enjoyment not his. Jesus Christ delivers you into humility--where there's no possibility of religious pomposity. Jesus Christ takes your brand new eternal life and hides it away with himself in God for safekeeping until he is manifest in glory, then your new life will be manifest as well. Until then, Jesus Christ who is now your life, takes your mortal life and hands it over to your neighbors so that you might be of some use to them while you wait for Jesus and his glory.
