A theology of preaching can help one to preach better. During the Protestant Reformation the emphasis moved from the sacraments to the Word preached. If you go into a medieval cathedral the architect placed the alter front and central in order to emphasize the mass. During the Reformation the eye was drawn to the pulpit; (which is the throne of God's Word). The design of a church sanctuary (past and present) reflects our theological convictions (good and bad).
The priority of preaching is not first and foremost a technical issue. We preach because it is the God-ordained way of communicating the gospel and building up the saints (2 Timothy 4:1-5; 1 Cor. 1:18-31; Col. 1:26-28). God is pleased to use the foolishness of preaching in order to accomplish His purposes on earth.
Martin Luther helped establish the centrality of the Word preached. In part, because Luther was committed to "nominalism" (as opposed to realism). This philosophical matter answers the following question, "Do words reflect reality or do they create reality?" Luther came to understand that justification is the declaration of God that a sinner is righteous having received the imputed righteousness of Christ (see 2 Cor. 5:21). The Latin expression of this is, “Simul Justus et Peccator” (simultaneously righteous and sinner).
