is to begin with the assumption that one must master the text. You know, the pastor, the "expert", equipped with all sorts of dictionaries and grammars has a go at the text. Then he takes the info from the text he's mastered and is given various techniques to knock it into shape and impart it to the "non-experts" - the laity! I don't think I'm being unfair as I reflect back on my own seminary training - that's what they attempted to teach us to do.
And it's all wrong. It goes wrong from the get go. The task of the preacher is not to master the text, not to interpret it, not to exegete it. Rather, the task of the preacher is to hear God addressing him through that text, interpreting him, exegeting him. The text and the God who speaks through it, is the Master. God would shape through that text the mind of Christ in those He addresses. And a big help in that is the whole community of those whom God has addressed - the Church who has heard Him speak through this text through the ages.
That God speaks a shattering word of law to humble pride of heart to save us (the Akathist of Thanksgiving) and that God speaks a sustaining, refreshing word of Gospel to impart and strengthen trust. Both together and neither alone - either by itself is formula for disaster for then God hasn't been heard all the way through.
And the beauty of this is that the preacher doesn't come to the pulpit as the resident expert, but as one among many whom God has addressed, and his whole task is to let others HEAR the address that he has heard: the God who humbles and who imparts trust to save us. The God revealed in the Cross of Christ as so for us that the spiritual attacks that come in their diversity and ferocity cannot shake that anchor that holds firm within the veil.
