Biblical, Systematic, and Historical Theology: A Reflection on their Relationship
Systematic theology is a reflection on and elaboration of the biblical texts (and their interpretations); biblical theology is the root of systematic theology while also being read in light of it. As the early church had it: the rule of faith is derived from the Bible, and the Bible must be properly read through the rule of faith. It’s circular but not vicious, indeed necessary for us who take these texts to be truthful witnesses to the God become flesh in Jesus Christ.
For example, Trinity in the Old Testament: if we really believe that God is triune, and we really believe that our same God was the one who chose and trained Israel, then we believe that Israel’s God was triune–and we should expect to find hints of this in their Scriptures, despite our conviction that God’s trinity didn’t become obvious until Jesus became human. This isn’t eisegesis; it’s an interpretive key rooted in the text itself. Still, collapsing biblical and systematic theology shouldn’t mean that what we’re really doing is systematic theology and co-opting the texts to serve our systematic purposes. Rather, a ‘systematic reading’ of the Bible only reflects our conviction that the God we read about in Romans is the same God that we find in the Exodus is the same God we find in Genesis and Revelation.
Can we really do biblical theology as a ‘simple’ interpretation of the texts? Even a theological reading of one circumscribed text (Scripture) has to make connections between concepts (reason), mediated socio-linguistically (experience), with critical and/or deferential reference to our own ways of thinking (tradition). Remember: doctrine is only a reading of the biblical text that’s been ‘settled’–a point of reference that the church decided was necessary to properly understand the texts. Its origin is not alien to the biblical text but precisely rooted there. So–if we trust the early church’s decisions on such things–we need not feel like we’re restricting our reading to pre-formed ideas; we’re rather using the hard-won wisdom of the church to dig deeper in our interpretations. On the other hand, the church is confident that if you begin without these guides but still with a confidence in the truthfulness of these texts, the same conclusions will win out–it just may take three or four hundred years, like it did in the beginning.
I’m less clear on the role of historical theology. We’re not interpreting normative texts this time, so we aren’t necessarily convinced beforehand that we’re going to find the God of Israel and of Jesus Christ. At the same time, we’re not modern historians who feel the need to bracket all theological and pastoral concerns when reading our older texts. We’re not historians of thought but rather Christian historical theologians, so our task remains concerned with the level of normativity even while we’re persistently concerned with historical accuracy. What’s our primary task: making sure we ‘have it right’ with the text, or allowing these past witnesses to instruct us in the faith and to correct them when necessary? There’s no necessary dichotomy between these two, of course. Getting the text right could be compared to listening closely to a friend in a conversation, not because getting what they’re saying is the end-goal but because the members of the body of Christ think it fruitful to be instructed by one another. And (hopefully) the conversation, to bring it back to where we started, is about how to read the biblical texts faithfully in a way that lets them be ‘useful for teaching, for reproof, for correction, and for training in righteousness.’ In other words, historical and systematic theology as biblical theology: an ongoing conversation and exposition of what we find in Scripture.
