Altar call
The invitation to come forward in response to a sermon, common in evangelical and Pentecostal services.
An altar call is the moment in an evangelical, Baptist, or Pentecostal service when the pastor invites attendees to come forward as a public response to the sermon. Typically the invitation is to profess faith in Christ for the first time, to rededicate one's life, or to seek prayer at the front of the church. The altar call is a distinctive Protestant practice, with roots in the eighteenth-century American revivalist tradition and the nineteenth-century camp meetings; it remains a prominent feature of much evangelical and Pentecostal worship.
