The New Testament distinguishes between preaching and teaching. Preaching is the proclamation of the Messiahship of Jesus, as revealed in his ministry, death, and resurrection. Preaching, therefore, occurs not in the worship of believers but in the public forum. The worship assembly is the setting for instruction in the faith and exposition of the Word of God. Although the sermon or homily of today may be a presentation of the gospel and an appeal for commitment to Christ, it had its origin as a part of worship in the teaching activity, rather than the public preaching, of the New Testament church.
Biblical Terms for Preaching
Preaching is the proclamation of the Word of God recorded in the Bible and centered in the redemptive work of Jesus Christ. Preaching summons persons to repentance, faith, and obedience. It is God’s appointed means for communicating the gospel of salvation in Christ to the unbelieving world and for strengthening the spiritual life of God’s people.
Of the many New Testament terms for preaching, the most characteristic is the verb kērussō, “to proclaim as a herald,” which occurs about sixty times (Matt. 3:1; Mark 1:14; Acts 10:42; 1 Cor. 1:23; 2 Tim. 4:2). The principal synonym is euangelizomai, “to announce good news, to evangelize,” a common verb used more than fifty times (Luke 3:18; 4:18; Acts 5:42; Rom. 10:15; 1 Cor. 1:17). Whereas kērussō stresses the activity of preaching as an announcement or heralding of the action of God, euangelizomai accents the message that is proclaimed as one of deliverance and hope. The combination “to proclaim the gospel” is also found (Matt. 4:23; Gal. 2:2).
In view of its prominence in the New Testament, it may seem surprising that the Old Testament seldom refers to the proclamation of the prophets as “preaching.” However, allowing the difference between prophetic proclamation (which is generally ascribed to a direct revelation from the Lord) and Christian preaching (which is the apostolic witness to the event of Jesus Christ), the prophets of Israel are properly regarded as the preachers of their day, the predecessors of the New Testament heralds of the gospel. The prophets proclaimed divine judgment because of the broken covenant and announced salvation to the repentant; the preacher of the early church came with a corresponding message, declaring that the covenant has been renewed in the mission, death, and resurrection of Jesus.
The Basic Content of Preaching
The synoptic Gospels summarize Jesus’ public ministry as one of preaching, teaching, and healing (Matt. 4:23; Mark 1:39; Luke 4:44). His message was the good news of the kingdom of God, with its demand that people should repent and believe in the gospel (Matt. 9:35; Mark 1:14–15; Luke 4:43). By this proclamation, Jesus signified that in his ministry the sovereign power of God had invaded history to establish a new reign of righteousness in the salvation of his people. Jesus conceived of his preaching ministry as a divine commission (Mark 1:38), in fulfillment of messianic prophecy (Luke 4:18–21).
The preaching of the apostles, as reported in Acts and gleaned from scattered fragments in the Pauline epistles, seems at first glance to strike a somewhat different note. Although the apostles are still said to preach the kingdom of God (Acts 28:31), the central affirmation of their message is the identification of Jesus as Messiah, the Lord, and Redeemer (Acts 2:22–36; 5:42; 11:20; 17:3; 1 Cor. 1:23–24; 2 Cor. 1:19; 4:5). This difference, however, represents not a contradiction but a progression. The kingdom of God that Jesus proclaimed achieved its triumph over the forces of evil and unleashed its creative power in the world through his own death and resurrection. In Christ, God’s sovereign power acted decisively and continues to act for the salvation of his people, so that beginning with the Resurrection, to preach the kingdom is to preach Christ (cf. Acts 8:12). Jesus himself both anticipated and authorized this shift of emphasis when he commanded his disciples to be his witnesses to the ends of the earth (Acts 1:8).
The apostolic message (kērugma) in its essential substance can be reconstructed according to this general outline: (1) In fulfillment of Old Testament prophecy, the new age of salvation has dawned through the ministry, death, and resurrection of Jesus, now exalted as Lord and Messiah. (2) The presence of the Holy Spirit in the church testifies to Christ’s present power and glory. (3) The messianic age will reach its consummation at the return of Christ in judgment. (4) God’s action in Christ promises forgiveness of sins, the gift of the Holy Spirit, and eternal salvation to all who repent and believe in Jesus.
On the basis of this reconstruction, the following observations can be made about the Christian message: (1) It consists of a definite body of facts. (2) It is essentially neither a doctrinal nor a philosophical system, still less an ethic, but it is a proclamation of those mighty acts in history whereby God has accomplished the salvation of his people. (3) It is centered in the person and work of Jesus Christ, especially in his cross and resurrection. (4) It is organically related to the Old Testament. (5) It imposes a forceful ethical demand on its hearers. (6) It has an eschatological dimension, looking forward to a realized fulfillment. The sermon that is inconsistent with these themes does not stand in the apostolic tradition of preaching.
Preaching and Teaching
The New Testament distinguishes between “preaching” and “teaching” (Matt. 4:23; 11:1; Eph. 4:11; 1 Tim. 2:7; 2 Tim. 1:11; 4:2–4). The publication of C. H. Dodd’s The Apostolic Preaching and Its Developments (New York: Harper, 1937) called attention to the difference between preaching and teaching in their New Testament senses, and it became fashionable in some circles to restrict the term preaching to evangelistic proclamation to the unconverted. Alan Richardson, for example, wrote, “In the New Testament, preaching has nothing to do with the delivery of sermons to the converted … but always concerns the proclamation of the ‘good tidings of God’ to the non-Christian world” (A Theological Word Book of the Bible [New York: Macmillan, 1950], 171–172). Understood this way, preaching in the New Testament is not a worship activity, comparable to the sermon of today, but the announcement (kērugma) of the Christian message to the unbelieving public. Within the Christian assembly, the speaker’s address might more properly be termed teaching or instruction (didachē), directed to already committed believers “to prepare God’s people for works of service, so that the body of Christ may be built up” (Eph. 4:12). Thus, throughout the history of Christian worship, the sermon or homily has often assumed the form of extended exposition of biblical passages, doctrinal instruction, ethical exhortation, or discussion of various aspects of Christian life and experience directed to largely Christian audiences.
The New Testament contains examples of sermons in the form of instruction in the principles and practice of the life of the new covenant community, such as Jesus’ Sermon on the Mount (Matt. 5–7) and the letter of James. The teaching function was an important role in the early church and one not to be taken lightly, as James himself stresses (James 3:1). Apparently, however, it was not restricted to certain designated officers. Paul indicated that teaching is one of a number of gifts with which certain members of the congregation might be endowed (Rom. 12:7), but also noted that in the Corinthian assembly “each one … has a teaching” (1 Cor. 14:26 nasb). The exposition of the Scriptures during the assembly of Christian worshipers was a continuation of the practice of the synagogue; after the Babylonian exile, biblical exposition emerged as an important and regular feature of synagogue worship.
However, the distinction between preaching and teaching in the New Testament is by no means absolute. Whereas Matthew reports that Jesus went about Galilee “teaching … [and] preaching” (Matt. 4:23), the parallel passages employ only the word preaching to describe this ministry (Mark 1:39; Luke 4:44). Where Matthew and Mark represent Jesus as preaching the gospel of the kingdom (Matt. 4:17; Mark 1:14–15), Luke says, “He taught in their synagogues” (Luke 4:15). More significant still, Mark uses these two terms interchangeably (cf. Mark 1:14–15, 31, 38–39). Elsewhere in the New Testament, the apostolic testimony to Jesus is likewise described in the same reference as both “preaching” and “teaching” (Acts 5:42; 28:31; Col. 1:28).
Teaching and preaching in the New Testament are intimately related and share the same basic content: the gospel of salvation through the death and resurrection of Jesus Christ, the Son of God. Teaching is simply the extension of preaching into the regions of doctrine, apologetics, ethics, and Christian experience. Preaching includes all these elements. The difference lies in emphasis, objective, and setting. Whereas the primary thrust of preaching is evangelistic, looking to the conversion of unbelievers, teaching unfolds and applies the fullness of the gospel to the total sweep of life, challenging and enabling believers to become more mature followers of Christ. The teaching function in the context of Christian worship is the necessary extension of the proclamation of the Christian message to the unconverted; it is the proclamation of “the whole purpose of God” (Acts 20:27 NASB; cf. 2 Tim.). The sermon in the context of a service of worship may be both kērugma and didachē; it may effectively appeal for conversion and commitment while instructing Christians in the teachings of Scripture and the principles of spiritual growth.
