"On Preaching" from the Confessions (#7)

"The distinction between law and Gospel is an especially brilliant light which serves the purpose that the Word of God may be rightly divided and the writings of the holy prophets and apostles may be explained and understood correctly. We must therefore observe this distinction with particular diligence lest we confuse the two doctrines and change the Gospel into law. This would darken the merit of Christ and rob disturbed consciences of the comfort which they would otherwise have in the holy Gospel when it is preached purely and without admixture, for by it Christians can support themselves in their greatest temptations against the terrors of the law." (Tappert, The Book of Concord. Fortress Press: Philadelphia, 1959, p.558; FC SD V: 1)

The classic book on this topic is the evening lecture series of C.F.W. Walther collected under the title: Proper Distinction Between Law & Gospel. Recently, Professor John Pless of CTS Fort Wayne authored Handling the Word of Truth: Law and Gospel in the Church Today. Browsing what else is available, I noticed that the professor under whom I studied homiletics has a 4 CD set available through CPH on the Proper Distinction as well as a paperback available through Amazon entitled: Sermon Form and Law-Gospel Preaching. Another volume that I have heard mentioned (though I have not read it) is Herman Stuempfle's Preaching Law and Gospel.
