In Christianity, a sermon is an address delivered to an assembly of Christians, typically containing theological or moral lesson. Although often called a homily, the original distinction between a sermon and a homily was that a sermon was delivered by a clergyman, while a homily was read by a layman. In the 20th century the sermons were likely to be longer, more structured, and hold greater theological content. Sermon types include: Biographical, Evangelistic sermons, Expository preaching, Historical sermons, Hortatory sermons, Liturgical sermons, Narrative sermons, Redemptive-Historical Preaching, and Topical sermons.
