Missouri Synod Lutheran pastors are taught in seminary it preach Law and Gospel as defined by C.FW. Walther. There is very little story telling and none of the “I” type sermons where the pastor puts himself into the sermon.
The basis Walther’s Law and Gospel was his twenty-fivetheses which were a series of lectures:
LAW AND GOSPEL.
The doctrinal contents of the entire Holy Scriptures, both of the Old and the New Testament, are made up of two doctrines differing fundamentally from each other, viz., the Law and the Gospel.
Only he is an orthodox teacher who not only presents all articles of faith in accordance with Scripture, but also rightly distinguishes from each other the Law and the Gospel.
Rightly distinguishing the Law and the Gospel is the most difficult and the highest art of Christians in general and of theologians in particular. It is taught only by the Holy Spirit in the school of experience.
The true knowledge of the distinction between the Law and the Gospel is not only a glorious light, affording the correct understanding of the entire Holy Scriptures, but without this knowledge Scripture is an remains a sealed book.
The first manner of confounding Law and Gospel is the one most easily recognized — and the grossest. It is adopted, for instance, by Papists, Socinians, and Rationalists, and consists in this, that Christ is represented as a new Moses, or Lawgiver, and the Gospel turned into a doctrine of meritorious works, while at the same time those who teach that the Gospel is the message of the free grace of God in Christ are condemned and anathematized, as is done by the papists.
In the second place, the Word of God is not rightly divided when the Law is not preached in its full sternness and the Gospel not in its full sweetness, when, on the contrary, Gospel elements are mingled with the Law and Law elements with the Gospel.
In the third place, the Word of God is not rightly divided when the Gospel is preached first and then the Law; sanctification first and then justification; faith first and then repentance; good works first and then grace.
In the fourth place, the Word of God is not rightly divided when the Law is preached to those who are already in terror on account of their sins, or the Gospel to those who live securely in their sins.
In the fifth place, the Word of God is not rightly divided when sinners who have been struck down and terrified by the Law are directed, not to the Word and the Sacraments, but to their own prayers and wrestlings with God in order that they may win their way into a state of grace; in other words, when thy are told to keep on praying and struggling until they feel that God has received them into grace.
In the sixth place, the Word of God is not rightly divided when the preacher describes faith in a manner as if the mere inert acceptance of truths, even while a person is living in mortal sins, renders that person righteous in the sight of God and saves him; or as if faith makes a person righteous and saves him for the reason that it produces in him love and reformation of his mode of living.
In the seventh place, the Word of God is not rightly divided when there is a disposition to offer the comfort of the Gospel only to those who have been made contrite by the Law, not from fear of the wrath and punishment of God, but from love of God.
In the eighth place, the Word of God is not rightly divided when the preacher represents contrition alongside of faith as a cause of the forgiveness of sin.
In the ninth place, the Word of God is not rightly divided when one makes an appeal to believe in a manner as if a person could make himself believe or at least help towards that end, instead of preaching faith into a person’s heart by laying the Gospel promises before him.
In the tenth place, the Word of God is not rightly divided when faith is required as a condition of justification and salvation, as if a person were righteous in the sight of God and saved, not only by faith, but also on account of his faith, for the sake of his faith, and in view of his faith.
In the eleventh place, the Word of God is not rightly divided when the Gospel is turned into a preaching of repentance.
