Systematic theology can be a helpful enterprise. A good one can help us frame biblical thought in ways to articulate what we believe with some clarity. Nevertheless it is good to ask if we tend to over emphasize our systematic theology of choice.
It is true the biblical text can feel like a reckless adventure. This is one reason we might feel the need for a systematic theology. Systematic theology makes things more predictable and helps us think we can know what happens next. On the other hand, reading the bible may have us feeling uneasy about what just happened or leave us with questions about why God acted that way. The biblical text brings surprise and leaves us with mystery.
We might feel uneasy about finding such a surprising unpredictable God. Yet this God is such a large part of the story that to tame Him with religious terms or to pretend we have Him figured out is to create an entirely different story. Still we formulate theories to explain biblical themes. While this can be full of good intention, it can come with a dangerous level of certainty. Systematic theology may bring assurance to some of us, but it does not always reflect what life looks like.
I fear our systematic theologies allow for a hermeneutic of dismissal. That is, permission to look past texts that do not support our systematic theory of choice. To gloss over any text or to force it down a particular path will only give us slivers of what the bible is actually trying to tell us. In the name of certainty and assurance we settle for slivers of God and slivers of grace and slivers of other things that matter.
Systematic theology comes with a temptation to be overly cognitive. If we can make it a thinking exercise then perhaps we will not have to behave differently. We sometimes give ourselves permission to make a verbal stand about something without demonstrating the behavior that reflects what we stand for. We can then preach holiness without being holy. We can then preach peace without being particularly interested in it. We can then preach grace as if it is something others should practice. We can then convince ourselves that to believe something and to say it out loud is more important than to change our behavior.
The bible was never intended to be a collection of proof texts to be pulled out on demand to make a case for our theories. The bible is the story of God’s mission in the world. All the text calls for is that the church will take it seriously. To become caught up in the reckless adventure that is the bible.
