The preacher, such as a pastor, imam, or rabbi, is a mediator of sacred text and tradition, calling people to faith, repentance, and righteous living. In poetry, the preacher can be a voice of moral authority, a figure of inspiration, or a target for satire. The rhetorical power of preaching—its rhythms, imagery, and urgent tone—heavily influences poetic traditions, particularly in spirituals and prophetic literature. The poet often takes on the preacher's role, bearing witness and speaking difficult truths.

Preachers—from Hebrew prophets to Baptist orators—interpret sacred texts for communal life; their rhetoric blends exhortation, storytelling, and moral urgency; in poetry, the preacher’s voice may appear as prophetic indictment, pastoral comfort, or lyrical invitation, often using repetition, call-and-response, or vivid imagery to move hearts.
