In his introduction to Colin Gunton's, Theology Through Preaching, Christoph Schwobel discusses "four interrelated aspects that make up the task of preaching theologically"
First of all, preaching theologically means preaching biblically, attempting to find the message for today's church in the patient engagement with the biblical texts.
Second, preaching theologically means preaching pastorally, so that preaching becomes part of pastoral care in the community of the church.
Third, preaching theologically also means preaching doctrinally, it means to recover the meaning of doctrine as guidance and aid for today's church.
Fourth, preaching theologically means preaching congregationally, acknowledging the place of the sermon in the life of a concrete congregation so that it can provide orientation for the way in which listening to the word of God, be it as preacher or as listeners, shapes the common lives of believers.
