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.
