The teachers I’ve learnt most from have been those who integrated both doctrine and ethics. Indeed, they didn’t see a dualism between the two. Today I was reading an essay by Stanley Hauerwas that summed up this idea of integration nicely. In critiquing the divide he says,
Those trained to do theology ‘proper’, however, seldom stray into ‘ethics’ as part of their job description. Too often theologians spend there time writing prolegomena, that is, essays on theological method meant to show how theology should be done in case anyone got around to doing any. Those who do try to do theology too often assume that their primary task is to construct a systematic presentation of theological loci and their interrelations. Ethics is what is done after one has accomplished these more primary tasks, or ethics becomes the responsibility of those who teach course in ethics.Stanley Hauerwas, “On Doctrine and Ethics” in The Cambridge Companion to Christian Doctrine (ed. Colin E. Gunton).
BTW – There’s a Hauerwas portal of sorts here with links to many online articles.
