A sermon is an oration, usually given by a member of the clergy, that preaches and teaches Christianity. Sermons are usually, but not always, delivered in a church. Most churches have a pulpit or an ambo, an elevated architectural feature from which sermons are given. Sermons are occasionally known as homilies, especially in Roman Catholicism and similar traditions.
Perhaps the most famous sermon in history was the Sermon on the Mount given by Jesus Christ. Throughout the history of Christianity there have been preachers noted for their sermons. Some of these include:
- St Stephen
- Tertullian

- St Francis of Assisi
- Lancelot Andrewes
