Holiness churches

Holiness adherents believe that the "second work of grace" (or "second blessing,") refers to a personal experience subsequent to regeneration, in which the believer is cleansed of the tendency to commit sin. This experience of "entire sanctification" enables the believer to live a holy life, and ideally, to live entirely without willful sin, though it is generally accepted that a sanctified individual is still capable of committing sin.

Though it became a multi-denominational movement over time and furthered by the Second Great Awakening which energized churches of all stripes, the Holiness movement has its roots in Wesleyanism.
